AbstractRecent technological and regulatory developments allow non-controllable renewable power plants such as photovoltaic, wind and hydroelectric plants to provide ancillary services to grid operators. This may represent a new source of revenue for renewable power plant operators and an improvement in the integration of power stations into the electricity grid. The income obtained by ancillary services provision is added to the revenue generated by the participation in the various electricity markets (daily, intraday). To maximize this revenue it is necessary to apply a strategy that optimizes the participation of renewables (or their aggregation in the form of a virtual power plant) to each market according to the opportunities. One of the barriers identified in this context is the need to reliably predict the value of the different quantities of the electricity market and system services (daily, intraday, adjustment, primary and secondary reserve prices and activation likelihood and direction) at different horizons (from 5 minutes to 48 hours). This research is part of the European project 'REgions' which aims to manage a set of renewable virtual plants able to provide ancillary services. This project, coordinated by AIT, sees the participation of partners in France, Austria and Germany, including MINES ParisTech, Fraunhofer IEE, Engie Green and ENERCON.

Scientific Objectives: The objectives of this research are: 1) to improve the quality of forecasts of different market quantities related to system services and 2) to develop a strategy of participation in several markets of a virtual plant composed of non-controllable renewable plants. This highlights several challenges. Little attention has been given in the past to the prediction of the prices of the system services because of their reduced volume, of their variance and especially of the volatility related to their activations. The impact of activation frequency and direction, the interdependence with day-ahead and intra-day electricity prices and the impact of congestion represent sources of complexity that need to be addressed. It is also necessary to quantify the uncertainty of these forecasts. Regarding the participation in the virtual power plant market, the challenge is to develop one or more strategies for simultaneous participation in several markets that take into account: price and renewable production forecasts with their uncertainty, risk aversion of the operator, the penalties and the reliability of the control and dispatch systems of renewable plants.
