Abstract: The study carried out in this master thesis comes from a larger project from the ENTSO-E(gathering of the European Transmission System Operators (TSO)) focusing on introductionof a European platform for the exchange of balancing energy from frequency restorationreserves. The frequency restoration reserves are the power reserves that allow the TSO tobalance the consumption and the production. The management of these reserves istherefore strategic for the TSO. RTE (the French TSO) takes part to this European project andthis has led RTE to challenge its secondary sources sizing method. The sizing method goal isto do a level of reserve prescription for the next day. The objective of the thesis is toevaluate a new secondary sources sizing method. To achieve the objective, two main tasksare identified. The first is the adaptation of a sizing method suggested by the ENTSO-E. Thisnew sizing method should be applicable to the French power system and its specificities.This requires some modifications from the original suggested method. We will decline themethod into different scenarios with different parameters. The second task focuses on theevaluation of the different scenarios and the comparison with the current sizing method.The evaluation will investigate three aspects for each scenario: • The static aspect, which investigates the statistical characteristics of the scenario’sprescription. • The dynamic aspect, which evaluates the impact of the scenario’s prescription on thepower grid. • The economic, which investigates the scenario’s cost. At the end of the study, RTE will dispose of a set of scenarios that are applicable to theFrench system with satisfying performances in order to select the best scenario consideringits cost/efficiency balance.
