摘要： 随着光伏发电在电网中渗透率的不断增加，光伏发电功率的不确定性和间歇性引起的光伏并网和弃电问题已引起关注。而采用"光伏+储能"的模式，却能有效缓解这一问题。在考虑储能电池容量衰退和光伏弃电率下，通过对不同光伏子阵配备的不同类型储能电池系统的运行进行仿真模拟，以消除光伏发电随机波动特性对电网的冲击为目的，研究平滑输出场景下分布式储能系统的电池的操作策略，优化储能系统中各储能电池子阵的运行。最后，采用共和地区20 MW （峰值）储能实证基地项目多电池储能系统实际案例对本模拟方法进行了验证。

Abstract: With the increasing penetration of the photovoltaic (PV) power generation system into the grid, the problems of the power of the PV power generation system into the grid and the PV electricity curtailment, which are caused by the uncertainty and intermittence of the PV power generation system have attracted attention. However, the "PV + energy storage" mode can effectively alleviate these problems. Taking the battery capacity degradation characteristics and the PV electricity curtailment into consideration, this paper simulates the operation of the system composed of the different PV power generation subsystem with the distinct types batteries, aiming to eliminate the impacts of the fluctuation characteristics of PV power generation on the grid. What's more, this work studies the operation strategy of the distributed energy storage system under the output smoothing scenario, and optimizes the operation of each energy storage battery array in the energy storage system. Finally, a practical case study of 20 MW (peak value) multiple types battery energy storage system in Republic area is used to verify the simulation method.

Key words: output smoothing scenario, distributed energy storage system, photovoltaic power generation, operation strategy, capacity degradation characteristics
