A broad review on optimal operation of Virtual power plant

In today's world virtual power plant plays a major role to aggregate distributed energy resources (DERs) to the electricity market. The procedure, objectives and the scheduling problems of DERs is a very important issue in the power system. This problem can be eliminated by VPP concept. Virtual power plant can be employed for different purposes and has its own special significance. So, a thorough literature review is necessary in this field. In this paper the optimization techniques of VPP is studied from various aspects and with different framework. A framework of optimal operation is presented in this review.
