摘要：
Reasonable control of multiple energy forms for load power supply can effectively improve economy and reliability of microgrid(MG) operation, however, these two problems of siting hybrid energy systems(HEMS) and scheduling them are separately solved.In order to optimize flexible power supply capacity, an algorithm was put forward to solve the problem of allocation and schedule of multiple hybrid photovoltaic (PV)-diesel distributed generation(DG) in distribution systems optimally.Firstly, an energy control method of HEMS was presented to improve efficiency and flexibility of MG operation; Secondly, an optimization problem was formulated considering not only to reduce the total investment, operation maintenance cost, network loss caused by imported power from the transmission grid, and un-served load in case of emergency, but also to maximize the excess generated power by the HEMS that may be injected into the distribution network; Finally, an improved artificial bee colony (ABC)based on particle swarm optimization(PSO) was put forward to increase convergence speed.Simulation results show that the presented control method improves the economy of MG operation and reliability significantly. © 2017, Harbin University of Science and Technology Publication.
