摘　　要：在离网型光伏发电系统中,由于光伏发电的不稳定性以及随机性,常常会配备一定容量的混合储能装置,这是整个系统不可或缺的组成部分。本文在分析了光伏发电系统以及混合储能装置的工作特性的基础上,制定了系统控制策略,大建立系统仿真试验模型,并在该模型上进行了带不可变负载扰动及带可变负载扰动下系统动态试验,仿真结果表明该系统的系统配置及控制策略的可行性。In off-grid photovoltaic power generation system, due to the instability of photovoltaic power generation and randomness, often equipped with a certain capacity of hybrid energy storage device, which is an integral part of the whole system.Based on the a-nalysis of the photovoltaic power generation system and the work characteristics of the hybrid energy storage device, on the basis of this paper introduces the simulation model used in the simulation theory, and combining with actual simulation model and simulation results, this paper expounds the feasibility of this method.Experimental results prove the theoretical analysis is established, the test method is feasible.
