Comparative Analysis of Dispatching Algorithms for Distributed Energy Resources in Virtual Power Plant

The widely-used distributed energy resources (DER) puts forward new request of distributed generators to dispatch in grids with traditional generators. With analysis of distributed generators such as micro combined heat and power (CHP) units, the generic virtual power plant (VPP) technology is introduced, and the optimal scheduling algorithm of resources in VPP is analyzed. Then three kinds of improved scheduling algorithms are proposed based on traditional scheduling program, and an example is taken to compare the optimization results and operation time of these algorithms. Conclusions is got that the linear programming heuristic (LPH) algorithm based on mixed integer linear programming algorithm and heuristic algorithm is the most economic and environmental scheduling algorithm for VPP owners with a faster computing time.
