  Kurzfassung

  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.

  Kurzfassung

  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.

  Prepared for regional self-supply? On the regional fit of electricity demand and supply in Germany³⁰
  2021 Energy Strategy Reviews, Band: 34, Seiten: 1 - 14
  » Kurzfassung anzeigen« Kurzfassung verbergen
  Kurzfassung

  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.

  How much energy autonomy can decentralised photovoltaic generation provide? A case study for Southern Germany ³³
  2020 Appl Energ, Band: 280
  » Kurzfassung anzeigen« Kurzfassung verbergen
  Kurzfassung

  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 Buildings³⁵

  Kurzfassung

  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.

  Bidding Strategies for Flexible and Inflexible Generation in a Power Market Simulation Model³⁹

  Kurzfassung

  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, Band: 70, Nummer: 7/8, Seiten: 36 - 39

  Kurzfassung

  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.
