Abstract

Microgrid plays an important role in the connection of distributed generation (DG) and power grid. Optimized operation of microgrid is an important aspect of in the research and development of microgrid. And an improved gravitational search algorithm (IGSA) is proposed to settle this problem. Gravitational search algorithm (GSA) is a new intelligent optimization algorithm, which has powerful global searching ability, good convergence and strong versatility and is easy to realize compared with other optimization algorithm. But it is easy to fall into local extremum for GSA. In the article, a multi-objective function of the optimized operation of microgrid is established.
