Economic and Technical Comparison of Energy Storage Technologies for Renewable Accommodation

Energy storage system (ESS) is the most promising flexible resource for renewable accommodation for the power systems with high penetration of renewable generation. There are a variety of ESS technologies with quite different technical and economic characteristics. Technology decisions of system planner and police-maker should be drawn based on rigorous quantitative analysis. A method of economic and technical comparison of energy storage technologies for renewable accommodation is proposed and a chronological production simulation with optimal scheduling of ESS is modeled for quantifying amount of renewable curtailment. In the case study, 4 types of ESS technologies with their typical parameters are applied in the power system. The results shows that PHS has the best comprehensive performance for renewable accommodation.
