Virtual power plant(VPP)has been considered to be one of the most effective ways to achieve the secure
reliable and economic operation of power system with distributed energy resources accessed. The dispatch optimization strategies of the commercial VPP(CVPP)are reviewed. The general concept
control framework
and available energy markets for VPP are introduced at first. Then optimization strategies of the CVPP participating various markets are analyzed containing the designing and solution of dispatch optimization model. The dispatch measures coping to the unbalanced power and the bidding strategy are introduced and reviewed in detail. Finally
the existing problems and future development involved in the dispatch optimization of CVPP are pointed out. This work is supported by State Grid Corporation of China(No. PD71-14-003).
