Abstract: The Security of Electricity Supply (SoES) is under threat in many regions. We develop a comprehensive but flexible framework to assess the SoES of a region, with two aims: (i) provide a snapshot of the situation to understand current weaknesses and determine what actions are required; (ii) capture the evolution over time to identify progress and discover new problem areas, thus providing an indicator of the effectiveness of current actions and of the need to adapt.

Abstract: An integrated bottom-up optimisation model of the German electricity generation and storage system performs capacity planning and unit commitment. A timely decomposition with myopic and rolling-horizon approaches enables both a long time horizon and high temporal resolution. This paper analyses the effects of varied model parameters on the solution time and robustness. A foresight of 24 hours and a combination of load change costs and part load efficiency offer the most practical compromise.

Abstract: Increasing feed-in of electricity produced by renewables and rising demand of electric vehicles challenge today’s electricity systems. Local coordination mechanisms to balance generation and demand in the distribution grid provide an opportunity to avoid grid congestion and to exploit load shifting potentials. In this paper we analyze the effects of introducing local markets by using agent based simulation and linear programming. Two case studies complement the analysis.
