Coordinated Energy Trading Model for Cooperative Microgrids Considering Uncertainties

A growing number of microgrids (MGs) with high-penetration photovoltaic generators (PVGs) and different load users is being deployed in the urban smart grid. So those MGs located nearly as stakeholders may form a cooperative alliance to share surplus energy reciprocally in the future retail markets. An effective mechanism is need to coordinate the energy trading of cooperative MGs regarding this trend. In this context, a decentralized coordinated operation framework is constructed to coordinate the energy trading among MGs bound to a cooperative alliance. Furthermore, two-stage robust optimization model is introduced for optimal operation of each MG. The controllable elements in MG include charge-discharge power of energy storage, adjust amounts of demand response, and trading power among MGs. A simulation case on three MGs is used to validate the effectiveness of present framework.
