微电网分层控制及其电能质量改善研究

Research on Stratified Control of Microgrid and Improvement of Power Quality

微电网作为一种新型的能源供应方式,代表着电力供电系统在新时期的发展方向。但由于其发展还不够成熟,供电过程中,电力存在不连续和不稳定的问题,直接影响到用户的使用。微电网在运行中会现电压连续跳动、瞬间停电等情况,严重降低了电能的稳定性。本文通过介绍微电网的电力特性,提出解决微电网运行过程中电能质量问题的一些方法。

As a new type of energy supply,microgrid represents the development direction of electric power supply system in the new century.However,due to its immature development,there are some problems of discontinuity and instability in the power supply process,which directly affects the user’s power usage.During the operation of the microgrid,the voltage continuously jumps and the instantaneous power failure occurs,which seriously reduces the stability of the electrical energy.This paper proposes a method to solve some power quality problems in the operation of microgrid by introducing the power characteristics of the microgrid.
