摘要
为解决分布式电源造成的电压扰动问题,提出基于交直流混合供电的微电网技术。由分布式电源的工作原理出发分析其变化特性;利用PSCAD平台搭建分布式电源模型,进行微电网控制策略下的仿真试验。仿真结果表明,微电网技术能够有效改善分布式电源并网后的电压输出,以及在孤网运行时保证内部基本电能供应,增强分布式电源供电的可靠性。
In order to solve the problem of voltage disturbance caused by distributed power generation, a microgrid technology based on AC/DC hybrid power supply is proposed. Based on the working principle of distributed power supply, the change characteristics of distributed power supply are analyzed, and the distributed power supply model is built by using PSCAD platform,and the simulation experiment under microgrid control strategy is carried out. The simulation results show that the microgrid technology can effectively improve the voltage output of the distributed power supply, ensure the internal basic power supply during the isolated grid operation, and enhance the reliability of the distributed power supply.
