In order to deal with the microgrid with cold,heat and power demand,an environmental and economic dispatch model considering electricity storage, heat storage device,and cold storage device was proposed．With the real-time supply and demand balance of cold,heat and power and micro sources and energy storage device output limits as constraints in the model,the total cost consisting of economy and environment cost of the microgrid operation was the objective function．A microgrid concluding gas turbine,fuel cell,waste heat boiler,absorption refrigerating machine,energy storage devices,was selected,which was solved by the algorithm of chaotic partial swarm．The example prove the validity of the proposed model and algorithm,and dfferent effects that different kinds of energy storage devices have on the target are discussed．The results show that the battery has caused loss increase,but can improve the economic operation,and cooling and heat storage device can help gas turbine to determine the output,and reduce loss and cost．
