The load characteristics should be considered in allocation of energy storage for industrial PV microgrid. The purposes of the allocation are ensuring the reliability of power supply and improving the photovoltaic utilization. The paper analyzes the operating characteristics and the impact of starting feature of industry sensitive loads in the PV microgrid for industries. In this paper, energy storage system charging and discharging control strategy based on industry time of use electricity price (TOU) mechanism which is applicable to industrial PV microgrid is proposed. Based on the analysis of main issues of the problem, a multi-objective optimization model is proposed and optimization approach based on NSGA-II algorithm is presented to search the optimal solution. The proposed operating strategy and optimization method are then tested on a Guangdong photovoltaic micro-grid. Results demonstrate that the optimized storage system can meet the requirement of expectation of system uptime under extreme conditions when operate autonomously and improve the PV power consumption rate while interconnect to the grid.
