Optimal Operation of Energy Storage Systems for Peak Load Shaving Application

In this paper, an optimal power flow (OPF) model is developed to incorporate energy storage systems (ESSs) and renewables into power systems. ESSs are utilized for peak shaving application. The model aims at minimizing system generation cost while taking into account system limits and ESS constraints. Tests are carried out on modified IEEE 14-bus system. Simulation results show that the ESS can effectively improve system performance.
