Multi-Objective Optimization of Operational Schedule of DG Units in the Presence of Demand Response

optimal operation of energy resources of distribution system causes to improve the efficiency of power network. So in this study, optimization of operational schedule of multi distributed generation and grid is done with consideration of demand response program. Diesel generator, micro turbine, fuel cell, wind turbine and photovoltaic are considered as DG units. To get the best result, firstly, economic and environmental indices are optimized by multi-objective particle swarm optimization. Then, analytical hierarchy process is used for selecting the best result from the Pareto optimal fronts. The obtained numerical results indicate the impact of proposed method on improving the economic and environmental indices of distribution system.
