Economic and Technical Modeling to Optimize the Use of Energy Storages for Energy Planning

One of the most interesting issues for power system operators is the load curve variability and non-uniformity that causes the power system to have higher operation costs. Power systems usually use high capacity and long-lasting storage units for operational storage and high speed response storage for frequency saving. To compar operation storage and frequency and to evaluate their impact on cost-effective power system operation, This paper attempts to analyze the role of pumped storage, compressed air storage and battery storage systems in an IEEE standard 118-bus test system (54 thermal units) by GAMS software. The simulation results show that the pumped storage units are more cost-effective opration performance than other two types of storage equipments. However, battery storage due to their lower start-up cost units are better than compressed air energy storage with higher capacit
