Management of uncertainties related to renewable generation participating in electricity markets

Abstract : The operation of Renewable Energy Sources (RES) units, such as wind or solar plants, is intrinsically dependent on the variability of the wind or solar resource. This makes large scale integration of RES into power systems particularly challenging. The research work in the frame of this thesis focuses on the participation of renewable power producers in liberalized electricity markets, and more precisely on the management of the regulation costs incurred by the producer for any imbalance between the contracted and delivered energy. In such context, the main objective of the thesis is to model and evaluate different methods for the management of imbalance penalties related to the participation of renewable power producers in short-term electricity markets. First, the thesis gives a classification of the existing solutions for the management of these imbalance penalties. A distinction is made between physical solutions which are related to the generation portfolio, and financial solutions which are based on market products. The physical solutions are considered in the frame of a Virtual Power Plant. A generic model of the imbalance penalty resulting from the use of physical or financial solutions is formulated, based on a market rule model. Then, the decision-making problem relative to both physical and financial solutions is formulated as an optimization problem under uncertainty. The approach is based on a loss function derived from the generic imbalance penalty model. Finally, the uncertainty related to the RES production is considered in the risk-based decision making process. The methods are illustrated using case studies based on real world data.
