摘要
作为分布式电源的有效组织形式,微电网通过整合分布式发电和配电网之间的关系,实现了分布式发电可控,解决了分布式发电接入配电网的问题。微电网可视为大电网的可控单元,可并网运行也可孤立运行。讨论了微电网与分布式发电的关系,分析了基于PQ控制的微电网控制运行策略及基于Matlab/Simulink的仿真环境并进行了验证。结合具体案例,由仿真测试结果得出所做设计能使有源网络及其分布式电源得到有效控制的结论。
Microgrid is an effective organization form of the distributed generation(DG).Microgrid technology integrates the relationship between DG and distribution network,which makes the DG controllable,and solves the problem of DG access to distribution network.Microgrid can be regarded as a controllable unit of the power grid,and can run in either grid-access or in isolation.This paper discusses the relationship between microgrid and distributed generation,analyzes the operation strategy of microgrid control strategy based on PQ control,and verifies in the simulation environment based on Matlab/Simulink.Combined with the specific case,the simulation results show that the design can effectively control the active network and its distributed power supply.
