Abstract：

The integrated planning of energy storage and photovoltaic power generation system can improve the PV self-dissipation capability, enhance coordination and flexibility, and improve economic benefits. It has broad development prospects and the importance of configuration of photovoltaic and energy storage equipment is also growing. A linear planning model of battery energy storage capacity and power configuration was established for collective optimum calculation on battery capacity, power, annual battery charge and discharge power and power purchase and sales power to conclude a battery charge and discharge strategy and capacity configuration with maximum economic benefits. The paper takes a real case study of an industrial park to determine the planning scheme of batteries that can achieve the best economic benefits; at the same time, based on the resulting internal rate of return and the photovoltaic self-distribution rate, the paper studies the change rules of feed-in tariff of photovoltaic power, energy storage battery cost, battery life and discount rate that go with battery energy storage capacity configuration and economic benefits as well as the role of the battery in this system.

Key Words： photovoltaic power generation;battery energy storage;capacity configuration and operation;internal rate of return;PV self-consumption ratio
