  Abstract

  In der deutschen Industrie muss ein Großteil des Anlagenparks mit Lebensdauern von bis zu 70 Jahren bis 2030 erneuert werden. Hierbei ist es für die Erreichung von Klimaneutralität zwingend erforderlich, dass neue CO2-arme Technologien zum Einsatz kommen. Insbesondere die Elektrifizierung der Prozesswärmeerzeugung als Haupttreiber der Emissionen in der deutschen Industrie bietet ein hohes Potential für die Dekarbonisierung. Zudem können elektrifizierte Prozesse zum Teil auch Flexibilität bereitstellen, um auf das schwankende Angebot von Wind- und Solarstrom reagieren zu können.

  Understanding Power Market Dynamics by Reflecting Market Interrelations and Flexibility-Oriented Bidding Strategies
  2022 Energies, volume: 15, issue: 2, supplement: 494, pages: 1 - 24
  » show abstract« hide abstract
  Abstract

  Power markets are becoming increasingly complex as they move towards (i) integrating higher amounts of variable renewable energy, (ii) shorter trading intervals and lead times, (iii) stronger interdependencies between related markets, and (iv) increasing energy system integration. For designing them appropriately, an enhanced understanding of the dynamics in interrelated short-term physical power and energy markets is required, which can be supported by market simulations. In this paper, we present an agent-based power market simulation model with rule-based bidding strategies that addresses the above-mentioned challenges, and represents market participants individually with a high level of technical detail. By allowing agents to participate in several interrelated markets, such as the energy-only market, a procurement platform for control reserve and a local heat market representing district heating systems, cross-market opportunity costs are well reflected. With this approach, we were able to reproduce EPEX SPOT market outcomes for the German bidding zone with a high level of accuracy (mean absolute percentage error of 8  /MWh for the years 2016–2019). We were also able to model negative market prices at the energy-only market realistically, and observed that the occurrence of negative prices differs among data inputs used. The simulation model provides a useful tool for investigating different short-term physical power/energy market structures and designs in the future. The modular structure also enables extension to further related markets, such as fuel, CO2, or derivative markets.

  An MILP model for evaluating the optimal operation and flexibility potential of end-users
  2021 Appl Energ, volume: 282, issue: Part B
  » show abstract« hide abstract
  Abstract

  It is expected that end-users from all sectors should participate in providing system flexibility, as variablerenewable energy is increasingly integrated into electricity systems. The ability of end-users to shift theirelectricity profiles has considerable potentials and can serve many purposes, e.g. to curb the peak loador to increase self-consumption. However, evaluation methods designed for flexibility from conventionalpower plants may be inadequate for flexibility from end-users due to the diverse constraints of underlyingprocesses and limitations related to individual needs. This work presents a comprehensive and modularflexibility model developed from common operational characteristics of flexible processes as an alternativemethod.The model is applied to two examples: First, the operation of a combined heat-and-power plant includinginput and output storage is optimized with the objective to increase profits from electricity sales on the spotmarket. Second, a steel rod production line consisting of melting, casting, and milling processes is scheduled sothat operating costs, including peak power costs, are minimized. Moreover, potentials of flexibility as externalservices and related costs are analysed. In this paper, the model is used to calculate the optimal costs (e),time-dependent flexibility potentials (kWh) and costs of flexibility provision (e/kWh). Thus, the adaptabilityand versatility of the model are demonstrated. As a modelling template, the model can ease the efforts ofstakeholders in the characterization and evaluation of various flexible processes, especially those from smalland medium-sized users.

  Abstract

  Since the beginning of energy sector liberalization, the design of energy markets has become a prominent field of research. Markets nowadays facilitate efficient resource allocation in many fields of energy system operation, such as plant dispatch, control reserve provisioning, delimitation of related carbon emissions, grid congestion management and, more recently, smart grid concepts and local energy trading. Therefore, good market designs play an important role in enabling the energy transition towards a more sustainable energy supply for all. In this contribution, we retrace how market engineering shaped the development of energy markets, and how the research focus shifted from national wholesale markets towards more decentralized and location-sensitive concepts.

  Getting more with less? Why repowering onshore wind farms does not always lead to more wind power generation – A German case study
  2021 Renewable Energy, volume: 180, pages: 245 - 257
  » show abstract« hide abstract
  Abstract

  The best wind locations are nowadays often occupied by old, less efficient and relatively small wind turbines. Many of them will soon reach the end of their operating lifetime, or lose financial support. Therefore, repowering comes to the fore. However, social acceptance and land use restrictions have been under constant change since the initial expansions, which makes less area available for new turbines, even on existing sites. For the example of Germany, this study assesses the repowering potential for onshore wind energy in high detail, on the basis of regionally differentiated land eligibility criteria. The results show that under the given regional criteria, repowering will decrease both operating capacity and annual energy yield by roughly 40% compared to the status quo. This is because around half of the wind turbines are currently located in restricted areas, given newly enacted exclusion criteria. Sensitivity analyses on the exclusion criteria show that the minimum distance to discontinuous urban fabric is the most sensitive criterion in determining the number of turbines that can be repowered. As regulations on this can vary substantially across different regions, the location-specific methodology chosen here can assess the repowering potential more realistically than existing approaches.

  Prepared for regional self-supply? On the regional fit of electricity demand and supply in Germany
  2021 Energy Strategy Reviews, volume: 34, pages: 1 - 14
  » show abstract« hide abstract
  Abstract

  Decentralized systems seeking to balance electricity supply and demand regionally are increasingly being discussed. Regional flexibility concepts, however, require spatially and temporally highly resolved knowledge. To provide this, we investigate the 2030 demand, supply, and demand-side flexibility for the German NUTS-3 regions. We (1) model the hourly regional electricity demand and supply, (2) cluster regions with regard to the regional demand and supply fit and (3) evaluate demand response for the identified clusters. While in windy or industrialized regions, the impact of demand response is low, in urban regions on the other hand, the effectiveness of flexible end uses is higher and residual load is flattened. Regions with medium-sized cities or those with smaller energy-intensive industries show a good regional fit. Here, demand response can be used very effectively to increase the regionally consumed share of electricity.

  Analysis of Avoided Transmission Through Decentralized Photovoltaic and Battery Storage Systems
  2020 IEEE T Sustain Energ, volume: 11, issue: 3, pages: 1922 - 1929
  » show abstract« hide abstract
  Abstract

  Decentralized renewable energy systems can be low-carbon power sources, and promoters of local economies. It is often argued that decentralized generation also helps reducing transmission costs, as generation is closer to the load, thus utilizing the transmission system less. The research presented here addresses the question whether or not, or under what circumstances this effect of avoided transmission can actually be seen for a community-operated cluster of photovoltaic (PV) power plants in two sample locations, one in Germany and one in Japan. For the analysis, the newly developed instrument of MPI-MPE diagrams is used, which plot the maximum power import (MPI) and maximum power export (MPE) in relation to the reference case of no local generation. Results reveal that for moderately sized PV systems without battery storage, avoided transmission can be seen in the Japanese model location, but not in Germany. It was also found that an additional battery storage can lead to avoided transmission in both locations, even for large sizes of installed PV capacity.

  How much energy autonomy can decentralised photovoltaic generation provide? A case study for Southern Germany
  2020 Appl Energ, volume: 280
  » show abstract« hide abstract
  Abstract

  Energy autonomy, the desire to become independent from a centralised supply system, is a core motivation for the development of decentralised energy systems, even if it does not have tangible economic or ecological benefits. For the case of electricity, we introduce a regional system model which optimises the capacity expansion and operation of photovoltaics and battery storage. We quantify cost-efficient regional degrees of electricity autonomy for 166 regions in Southern Germany and assess how increasing the degree of autonomy beyond the optimal level affects the economic viability of a decentralised electricity system. We find that the average optimal degree of autonomy reached is 44%. Thus, our results show that a substantial increase of photovoltaic capacity is economically beneficial in all the regions examined. However, achieving a predefined degree of autonomy causes additional costs for the region and results in a large overcapacity, while all regions still rely on the superordinate electricity system to some extent.

  Profitability of Photovoltaic and Battery Systems on Municipal Buildings
  2020 Renew Energ, volume: 153, pages: 1163 - 1173
  » show abstract« hide abstract
  Abstract

  The increasing gap between electricity prices and feed-in tariffs for photovoltaic (PV) electricity in many countries, along with the recent strong cost degression of batteries, led to a rise in installed combined PV and battery systems worldwide. The load profile of a property greatly affects the self-consumption rate and, thus, the profitability of the system. Therefore, insights from analyses of residential applications, which are well studied, cannot simply be transferred to other types of properties. In comparison to residential applications, PV is especially suitable for municipal buildings, due to their better match of demand and supply. In order to analyze the value of additional batteries, municipal PV battery systems of different sizes were simulated, taking load profiles of 101 properties as inputs. It was found that self-consumption differs significantly from households, while different types of municipal buildings are largely similar in terms of the indicators analyzed. The share of electricity consumed during summertime was found to have the most significant impact on the self-consumption rate for most considered system sizes. Due to lower electricity tariffs and lower increases in self-consumption provided through batteries in municipal buildings, the investment into a battery is not economically advantageous in most of the cases considered.

  Reducing Operational Costs of Offshore HVDC Energy Export Systems Through Optimized Maintenance
  2020 Energies, volume: 13, issue: 1146, pages: 1 - 20
  » show abstract« hide abstract
  Abstract

  For the grid connection of offshore wind farms today, in many cases a high-voltage direct current (HVDC) connection to the shore is implemented. The scheduled maintenance of the offshore and onshore HVDC stations makes up a significant part of the operational costs of the connected wind farms. The main factor for the maintenance cost is the lost income from the missing energy yield (indirect maintenance costs). In this study, we show an in-depth analysis of the used components, maintenance cycles, maintenance work for the on- and offshore station, and the risks assigned in prolonging the maintenance cycle of the modular multilevel converter (MMC). In addition, we investigate the potential to shift the start date of the maintenance work, based on a forecast of the energy generation. Our findings indicate that an optimized maintenance design with respect to the maintenance behavior of an HVDC energy export system can decrease the maintenance-related energy losses (indirect maintenance costs) for an offshore wind farm to almost one half. It was also shown that direct maintenance costs for the MMC (staff costs) have small effect on the total maintenance costs. This can be explained by the fact that the additional costs for maintenance staff are two orders of magnitude lower than the revenue losses during maintenance.

  The cost of providing operational flexibility from distributed energy resources
  2020 Appl Energ, volume: 279, pages: 1 - 16
  » show abstract« hide abstract
  Abstract

  Flexible household devices, such as heat pumps combined with thermal energy storage or battery energy storage units, can provide flexibility to the electricity sector. However, to make flexibility available to the market, it has to be correctly quantified, and its cost has to be estimated. In this work, a methodology for generic flexibility quantification is proposed and developed in a Python environment using model predictive control. The chosen methodology allows to quantify the adjustable power, and also to determine the corresponding cost of the flexibility provision. It was observed that the available flexibility and its cost is influenced by many factors such as system components, human behavior, building thermal parameters, and price signals. Also, the inclusion of even a low share of households with batteries or electric vehicles smoothens the aggregated flexibility profile, and a considerable amount of flexibility is available at almost any point in time.

  Abstract

  Consumption-based carbon emission measures aim to account for emissions associated with power transmission from distant regions, as opposed to measures which only consider local power generation. Outlining key differences between two different methodological variants of this approach, we report results on consumption-based emission intensities of power generation for European countries from 2016 to 2019. We find that in particular for well connected smaller countries, the consideration of imports has a significant impact on the attributed emissions. For these countries, implicit methodological choices in the input-output model are reflected in both hourly and average yearly emission measures.

  Operational Flexibility of Small-Scale Electricity-Coupled Heat Generating Units

  Abstract

  Heat generation that is coupled with electricity usage, like combined heat and power generators or heat pumps, can provide operational flexibility to the electricity sector. In order to make use of this in an optimized way, the flexibility that can be provided by such plants needs to be properly quantified. This paper proposes a method for quantifying the flexibility provided through a cluster of such heat generators. It takes into account minimum operational time and minimum down-time of heat generating units. Flexibility is defined here as the time period over which plant operation can be either delayed or forced into operation, thus providing upward or downward regulation to the power system on demand. Results for one case study show that a cluster of several smaller heat generation units does not provide much more delayed operation flexibility than one large unit with the same power, while it more than doubles the forced operation flexibility. Considering minimum operational time and minimum down-time of the units considerably limits the available forced and delayed operation flexibility, especially in the case of one large unit.

  Promoting flexibility from prosumers through a generic characteristic flexibility model
  2019 11. Internationale Energiewirtschaftstagung an der TU Wien
  » show abstract« hide abstract
  Abstract

  Energy systems require flexibility - an ability to respond to changes - to integrate higher shares of variable renewable energy. On the whole, flexibility potential from prosumers is significant and stems from various processes. As each flexibility option is unique, before utilization, its potential first must be assessed. This paper presents a universal flexibility model, so called generic characteristic flexibility model (GCM), as tool to characterize and assess most, if not all, flexibility options from prosumers. GCM establishes a generic flexible process with components representing physical parts, e.g. machine and storage, and various administrative decisions, e.g. changes in output delivery or operating hours. Each component is described with essential characteristics and constraints. As demonstrations, three flexible systems representing various sectors – a district heating system, a household appliance, and a production process - are characterized and modelled using GCM. Flexibility in these systems is utilized to minimize costs under time-varying electricity prices and subject to operational constraints. This in turn proves the concept of a universal flexibility model. GCM eases burdens of actors - flexibility providers and users - to develop assessment tools for each flexibility options. Its pre-defined structure and characteristics also support identification of flexible processes and communication between actors. Thus, it helps promoting the utilization of flexibility from prosumers.

  Abstract

  This paper presents an electricity market simulation model that focuses on the distinction between flexible and inflexible generation, and formulates bidding strategies for capacities of either type. Bid formulation for flexible power plants, storage and demand response units at a balancing power market and an energy exchange market are described, and exemplary results from the simulation model are presented. It is shown that the simulation model can realistically reproduce market outcomes for the example of the German market zone, and that it can also simulate negative market prices. Results reveal that power plants could be deployed in a more flexible manner than they are currently done in actual market operation, where larger variations of output are avoided especially for nuclear and lignite-fired power plants. The model can be used for analyzing future energy scenarios of high shares of variable renewable energy (VRE), and help answering research questions related to the required system flexibility for balancing out VRE fluctuations.

  Control algorithms for electrolyzers - Hydrogen from green electricity
  2018 BKW, volume: 70, issue: 7/8, pages: 36 - 39
  » show abstract« hide abstract
  Abstract

  In 2017, the share of renewables in power generation in Germany was around 33 %. By 2030, according to the will of the federal government, it should be as high as 65 %. A large proportion of electricity from wind and solar energy will in future require electricity storage. Particularly promising is the conversion to hydrogen. Research, industry and the energy sector are currently driving forward the development and use of water electrolysers. The Fraunhofer Institute for Solar Energy Systems ISE and the University of Applied Sciences Offenburg, in cooperation with the energy provider badenova and the gas network operator bnNetz have developed operating management algorithms for electrolyzers and tested them at research facilities. Within the project, the integration of hydrogen into municipal gas and electricity grids and into a local energy grid could be tested taking into account the current regulations and economic constraints. Thereby, the partners have laid important foundations for the use of the energy carrier hydrogen.
