The configuring energy storage according to technical characteristics usually starts with smoothing photovoltaic power fluctuations [1, 13, 14] and improving power supply reliability [2, 3]. Some literature uses technical indicators as targets or constraints for capacity configuration.
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.
The maximum power of energy storage systems is 0.9156 p.u, which is depicted in Fig. 7. The rated capacity is 0.834 p.u., the MPS wind energy loss is 0, which guarantees full connectivity to the internet, but the resulting energy storage system would cost a great deal. Fig. 7. Energy storage capacity and energy loss.
The actual operating conditions and battery life should be considered in the optimal configuration of energy storage, so that the configuration scheme obtained is more realistic.
Taking the annual comprehensive cost of the HESS as the objective function, a hybrid energy storage capacity optimization configuration model is established, and the dividing point N is used as the optimization variable to solve the model and obtain the optimal configuration results.
