考虑分区需求侧管理的交直流混合微电网能量优化调度

Optimal operation of energy management for AC/DC hybrid microgrid considering partition demand side management

考虑到交直流混合微网特殊的电气特性和网架结构,建立了交直流混合微网能量优化管理模型。针对交流区和直流区不同的负荷特性,分别对交流区负荷采用直接负荷控制和负荷中断方式,对直流区负荷采用负荷平移方法进行需求侧管理。通过算例验证所建模型适用于交直流混合微网,并能够借助需求侧管理技术提升微网的经济性和供电可靠性。

Considering the special electrical characteristics and grid structure of AC/DC hybrid microgrid, the optimal manage- ment model of AC/DC hybrid microgrid is established. According to the different load characteristics of AC/DC hybrid microgrid in AC and DC area, the direct load control and load interruption is used for AC area load, while the load translation is used for DC ar- ea load. A numerical example shows that proposed model is suit- able for AC/DC hybrid microgrid and can fully use demand side management technology to improve the economy of microgrid and the reliability of power supply.
