Simultaneous Energy Management of Micro-CHP Units and Storage Systems in Microgrids Considering Responsive Loads

A suitable energy management system (EMS) is an essential tool for optimal operation of a Microgrid with different resources considering uncertainties. In this paper, a day-ahead stochastic EMS is proposed in order to minimize the cost operation and maximize the reliability of Microgrid. The proposed EMS should supply electrical and thermal loads of Microgrid. A stochastic framework based on scenario generation is used to response the uncertainties of electrical load, market price and renewable energy sources (RESs). Also demand response programs (DRPs) are provided based on various load shifting contracts to consumers. In addition, both islanding and grid-connected operations of Microgrid are handled. Capability of the proposed method is proved by simulation results of a 3-feeder Microgrid with 7 generation units.
