Dynamic Equivalence Analysis of Distribution Network Integrated with High Penetration of Distributed Photovoltaic Generation System
摘要
Abstract
The penetration level of distributed photovoltaic (PV) generation in the power distribution network has been increasing quickly, and sometimes the penetration level can exceed 100%.The power distribution network even feeds power into the transmission network when sunshine is strong.In this case, the dynamic characteristics of power distribution networks are determined by both the electrical loads and PVs.A dynamic equivalent model for power distribution networks with high penetration of PV is proposed.The proposed equivalent model contains a complex load model and a photovoltaic power station.Moreover, the dynamic trajectory sensitivity method is employed to select key equivalent parameters.Then, on the combined simulation platform of DIgSILENT and MATLAB, genetic algorithm is employed to identify the key parameters of the dynamic equivalent model.Finally, an integrated transmission and distribution network is simulated on DIgSILENT platform, and the simulation results demonstrate that the proposed dynamic equivalent model for distribution networks can ensure the accuracy of the transmission network transient simulation.关键词
