基于一种综合控制策略的微电网控制与优化

Micro-grid Control and Optimization Based on a Comprehensive Control Strategy

微电网运行的主要难题是系统电压稳定性的控制,尤其是联网运行模式、孤岛运行模式以及联网和孤岛两种模式切换时的电压稳定性控制。针对传统控制算法控制效果不理想,存在忽略某些重要参数的现象,深入分析相关控制算法并提出一种综合控制策略用于提升微电网运行稳定性。对上述3种模式进行了MATLAB/Simulink仿真,仿真结果表明所提控制策略可以保证微电网安全稳定运行。

The main problem of micro-grid operation is the control of system voltage stability,in particular, the voltage stability control over switching between networked mode, of both isolated island modes, networking and isolated island mode. Aiming at the problem that the effect of traditional control algorithm is not ideal, some important parameters are ignored, the related control algorithm was deeply analyzed and a comprehensive control strategy was put forward to improve the stability of micro-grid operation. The three modes were simulated by MATLAB / Simulink. The simulation results show that the control strategy can ensure the safe and stable operation of micro-grid.
