The microgrid (MG) is a distribution system that integrates the increasing number of renewable energy resources, storage systems and controllable loads to support a flexible and reliable renewable energy distribution. Microgrids can be used for a broader range of applications in rural areas and disaster restoration efforts, and enable higher efficiency in managing uncontrollable renewable energy resources such as wind and solar. I will present two optimization problems that need to be resolved for the electrical community to receive benefits of having clean and high-quality power at lower cost. The first problem is to find an optimal amount of electrical power to produce and its price when a microgrid is used to trade (sell/buy) power with distribution system. We propose a decentralized pool strategy for an MG to integrate with a distribution system through a market mechanism to reduce the complexity of the system and improve the efficiency of the electricity market operation. The second part of the talk is about a two-stage microgrid scheduling strategy in which the frequency control reserve (FCR) is considered to ensure economic, reliable and stable microgrid operation.
