ANALYSIS OF WIND AND SOLAR SYSTEMS GRID INTEGRATION USING NEW TOOL FOR CURTAILMENT AND PENETRATION ASSESSMENT

Abstract

An important component of the variable renewable generation (VRG) integration in Romanian power grid represents the wind and solar curtailment energy due to the impact it can have on economics. This paper performs a quantitative assessment of both VRG penetration and curtailment ratio in Romanian grid using the new tool proposed in specialty literature named “C-P map”. It was only calculated the penetration ratio, for the curtailment ratio only being made interesting scenarios due to the lack of official data. This has allowed obtaining images of principle regarding near future tendency for the national power network, providing help in planning and decision making in order to optimize the VRG curtailment level and secure grid operating.
