Technical and Economic analysis of a Regulatory Call for PV Plants with Energy Storage in French Islands

Abstract

European incentive policies led to a faster development of renewable energy sources. This energy transition is bringing new challenges, in particular for grid stability. Photovoltaic energy combined with electrical storage system is one of the most promising technology to enable a massive insertion of green energy into the grid. The task of this paper is to study a call for tender launched by the French government in French insular regions, to develop PV plants equipped with electrical storage systems. The technical sizing will be carried on, using the software PVsyst. Then, the energy flows between the PV panels, the battery and the grid will be optimized thanks to an algorithm. The purpose is also to study the benefits and costs of such a system, and so different scenario will be considered, each one leading to a different economic interest. More broadly, this paper considers the role of batteries today, and how it should be rewarded or compensated for service delivery.
