The power system multi-objective optimization dispatching containing virtual power plant

摘要

Under the background of the rapid development of new energy technology, the concept of virtual power plant (VPP), which is composed of multiple types of DER, is proposed and a power system multi-objective optimization dispatching model of SCUC problem comprehensively considering total power generation costs, pollution treatment costs, unit start-up and stop costs is established and the node power transfer factor is introduced to deal with the static security constraints under DC load flow. The improved particle swarm optimization (IMPSO), a combination of PSO and Binary PSO (BPSO), is employed, and Matlab platform is used to solve the above model. At last, a case is adopted to prove the validity and feasibility of model and algorithm, which confirms that the research of VPP participating in dispatching is of far-reaching significance.
