Impact of Renewable Power Plant Collector System on Stability of Grid-connected Multi-converters
摘要
Abstract
The distributed parameters of collector feeders on the photovoltaic and wind farm have an important influence on the resonance of converters based on LCL filters , presenting a challenge to converter control system design . In order to investigate the impact of the renewable power plant collector system on the stability of grid‐connected multi‐converters , a mathematical model for the multi‐converter system is developed using the network admittance matrix in the complex frequency domain , and frequency characteristics are analyzed . It is shown that the influence on the stability of converters varies with topological form and feeder length of different feeder types in the collector system . The validity of the relevant conclusions is verified by simulation results based on MATLAB/Simulink .关键词
