摘　　要：基于含有储能单元的分布式发电系统,分别设计了单相电流环控制逆变器并网运行方式,以及单相电压电流双环控制的储能逆变器的双向、双模运行方式。在此基础上提出了含储能单元的分布式发电系统运行控制策略,并对系统处于离网状态时的储能系统的三种工作状态做出了具体分析。同时,基于MATLAB/Simulink仿真平台,对系统多种运行方式、状态进行了仿真研究。仿真结果表明,控制策略系统可以准确的执行给定的电压、电流指令,验证了提出理论的正确性;同时,设计的系统在并网、离网状态及并/离网切换时都可以为重要负载提供持续高质量的电能,证明了设计构成的系统具有较强的可行性和稳定性。Based on the distributed power generation system containing energy storage units,this paper proposes a grid-connected operational mode using a single-phase current-loop control inverter,as well as a bi-directional dual-mode operational method adopting an energy storage inverter controlled by a single-phase dual loop of voltage and current. Furthermore,it presents an operational control strategy for the distributed power generation system containing energy storage units,and three operational states of the energy storage system during the off-grid of the system are analyzed. In addition,simulation research is made on various operational modes and states of the system,based on MATLAB / Simulink simulation platform. The simulation results show that the system adopting above mentioned strategy can correctly execute given current and voltage instructions,and verify the correctness of the proposed theory. In the meantime,the signed system,in the connected / off grid status or at the switching moment,can provide continual high-quality electric power to important loads,thus proving the high feasibility and stability of the system construed in the design.
