摘要：

This paper constructs an economic dispatch model of an integrated energy system including grid, wind power, photovoltaic and energy storage devices based on combined cooling, heating and power system, and optimizes the dispatch model based on improved krill swarm optimization algorithm with the system integrated cost as the objective function, taking into account the electric power balance constraint, cooling and heating load balance constraint and each micro-source output constraint. The simulation results show that the improved krill swarm algorithm can reduce the daily integrated cost by $124.1 and $50.3 respectively, which can save 9.5% and 3.9% of the daily integrated cost compared with the conventional krill swarm algorithm and the artificial bee colony algorithm. The constructed integrated energy system model can effectively improve the energy utilization and economic efficiency of the system. (C) 2022 The Author(s). Published by Elsevier Ltd.
