AMIRIS - Agent based model for the integration of renewables into the electricity markets

The model AMIRIS allows the evaluation of political instruments and promotion mechanisms regarding their impact on actors‘ behaviours and development of the energy system. Actually the focus is set to energy economic changes due to the revised EGG 2012 and new possibilities of direct marketing of renewable electricity by § 33g (Marketpremium - MP), § 39 (Green electricity privilege) and local and regional direct marketing. Agents representing political framework, plant operators, intermediaries energy exchange market and distribution service operator are implemented in the model. Characteristics of the agents are based on beforehand performed analysis of actors. The poster shows the setup, simulation process and outcome of the AMIRIS model

Self-Reinforcing Electricity Price Dynamics under the Variable Market Premium Scheme

We report a potential self-reinforcing design flaw in the variable market premium scheme that occurs if variable renewable energy power plants receiving a premium become price-setting in the market. A high share of renewable energy is a goal of many countries on their transformation path to a sustainable future. Accordingly, policies like feed-in tariffs have been in place for many years in many countries to support investment. To foster market alignment, variable market premia have been introduced in at least 12 European countries and a further dozen additional countries world-wide. We demonstrate both with a mathematical model and different scenarios of an agent-based simulation that the combination of variable premia and a high share of hours in which renewables are price-setting may lead to a self-reinforcing downward spiral of prices if unchecked. This is caused by the market premium opening up the bidding space towards negative prices. We discuss possible objections and countermeasures and evaluate the severity of this market design flaw

New forecast tools to enhance the value of VRE on the electricity market: Deliverable D4.9

Project TradeRES - New Markets Design & Models for 100% Renewable Power Systems: https://traderes.eu/about/ABSTRACT: The present deliverable was developed as part of the research activities of the TradeRES project Task 4.4 - Enhancing the value of VRE on the electricity markets with advanced forecasting and ramping tools. This report presents the first version of deliverable 4.9, which consists on the description and implementation of the forecasting techniques aiming to identify and explore the time synergies of meteorological effects and electricity market designs in order to maximize the value of variable renewable energy systems and minimize market imbalances. An overview of key aspects that characterize a power forecast system is presented in this deliverable through a literature review. This overview addresses the: i) forecast time horizon; ii) type of approach (physical, statistical or hybrid); iii) data pre-processing procedures; iv) type of forecast output; and v) the most common metrics used to evaluate the performance of the forecast systems.N/

Der Beitrag der Marktprämie zur Marktintegration erneuerbarer Energien - Erfahrungen aus dem EEG 2012 und Perspektiven der verpflichtenden Direktvermarktung

Mit dem EEG 2012 wurde die gleitende Marktprämie in das Förderregime der erneuerbaren Energien zunächst als Option eingeführt. Das EEG 2014 baut diesen Ansatz durch verpflichtende Direktvermarktung weiter aus, ohne die Grundstruktur der Prämie anzutasten. Mit dem Instrument verbinden sich hohe Erwartungen an Kostensenkungen, die durch eine Steigerung der Vermarktungseffizienz und eine verstärkte Bedarfsorientierung von erneuerbaren Energien erzielt werden sollen. Der Beitrag wertet die bisherigen Erfahrungen mit der Marktprämie aus und geht der Frage nach, welche Effizienzgewinne durch die Weiterentwicklung im EEG 2014 realistisch sind

Self-reinforcing deflationary price dynamics under the variable market premium scheme

We report a potential self-reinforcing design flaw in the variable market premium scheme that occurs if variable renewable energy (VRE) power plants receiving a premium become price-setting in the market. A high share (>60%) of renewable energies is a goal of many countries on their transformation path to a sustainable future. Accordingly, policies like feed-in tariffs have been in place for many years in many countries to support investment. To further market alignment, variable market premia have been introduced. We demonstrate with an agent-based simulation model (AMIRIS) that the combination of variable premia and a high share of renewables in the market may lead to a downward spiral of prices if unchecked. Given current policy schemes, these results apply to at least 12 European countries and a dozen additional countries world-wide. Hence, we evaluate the severity of this market design flaw and discuss countermeasures
