Abstract

The power management in micro grid (MG) is related to the planning of dispatchable sources such as diesel generator or storage devices due to the fluctuation of output power of renewable sources like wind and solar. In the island mode, to balance the power in the case of output changing from wind and solar sources, the control trategy such as regulating the power of dispatchable generators and load shedding is necessary. This paper introduced the way to determine the load amount be shed for N ahead moment, based on conflict multi objectives, applying the Particle Swarm optimization algorithm and Belman-Zadeh principle to find out the strategy of generating the power in MG. The application for one medium voltage MG is also presented.
