OPTIMIZATION METHOD OF POWER GRID WITH HIGH PROPORTION POWER ELECTRONIC EQUIPMENT BASED ON NETWORK PARTITION PLANNING

首先研究电网中不同节点所接入分布式能源设备的距离特征以及电力电子设备的并网运行特性,提出含高比例电力电子设备电网的分区方法;然后针对电网分区后各区域间的协调能力,建立含高比例电力电子设备电网的最优规划模型;最后通过仿真算例验证该文所提方法和模型的准确性与有效性。

The optimization planning method for power grid planning with large-scale power electronic equipment is one of the effective ways to solve the challenges posed by improving the reliability of power gird when the distributed power sources are connected to the power grid.Firstly,the partition optimization method of the power grid with high proportion power electronic equipment was proposed based on the research of the operational characteristics of power electronic equipment and distance characteristics of distributed energy equipment connected to different nodes in the power grid.Then,the planning model of power grid with high proportion power electronic equipment was established based on the coordination ability between various regions after grid partitioning.Finally,based on simulation examples,the correctness and effectiveness of the method were verified.
