Optimal Configuration of Energy Storage System via MPC considering High Density Photovoltaics

In order to suppress the fluctuation of high density photovoltaic (PV) system, enhance the acceptance capability of the distribution network for PV power generation, and improve the utilization of solar energy, a side energy storage system with high density PV power distribution network will be built to coordinate and optimize the control, which can obtain better economic benefits and system stability. Also, an optimal allocation method based on model predictive control (MPC) is proposed. The method is aimed at energy storage system in distribution network with high density photovoltaics (HDPV). Considering the uncertainty of PV power generation and load demand, energy storage systems can obtain the lowest cost in the whole life cycle. The validity and superiority of the optimal allocation model are verified by the analysis of typical daily dispatch optimization in different seasons and the comparison with energy-storage-free system.
