摘要
Abstract
The voltage and frequency of distribution network will be affected as the access of distributed resources. Aiming at a microgrid composed of four different types of distributed sources, when it is connected with the distribution network, there are three operation modes: grid-connected mode, islanded mode and the mode-switch between the two modes. A microgrid control model with more realistic parameters is established. The simulation analysis of smooth transition of three cases is studied: switching microgrid operation modes, changing load during islanded mode, cutting and reconnecting one distributed source during islanded mode. The change of the power output of each distributed source,voltage and frequency of the AC bus in each case before and after the optimization are compared with each other. Simulation results show that the proposed power optimization control strategy is feasible and effective, and at the same time of achieving smooth transition, the rate of utilization of the distributed sources which are optimized can be improved.关键词
