摘要
为深入研究分布式电源的并网运行特性,需要建立多个不同电压等级和并网容量的分布式电源仿真模型来满足配电网的并网要求。针对含有分布式电源的配电网的仿真,提出了一种分布式电源仿真模型的功率变换方法。对具有标准输出电压和功率的分布式电源进行电压电流变换后再接入电网,以适应配电网对不同电压等级和容量的分布式电源的要求。建立了功率变换器的仿真模型,并将其应用于光伏发电系统并网仿真算例中。仿真结果表明,该功率变换方法是有效的和可行的,能提高分布式电源仿真模型的通用性和实用性。
For the further study about the operation characteristics of distributed resource （DR） connected to the grid, several DR simulation models with different voltage and capacity should be set up to meet the requirements of the distribution network. According to the simulation of the distribution network with DR, a method of power conversion for simulation model of DR is presented. In order to meet the requirements of distribution network for the DR with different voltage grade and capacity, the voltage and current of the DR which has standard output voltage and power will be converted to connect to the grid. The simulation model of power conversion is established and applied in the simulation examples of photovoltaic power generation system connected to the grid. Simulation results show that the power conversion method is feasible and effective, and can improve the universality and practicality of the DR simulation model.
