Dynamic Environmental Economic Dispatch Model of Combined Cooling Heating and Power Microgrid

Considering the uncertainties of wind and photovoltaic power output and cooling, heating and power load forecasting values in micro-grid, the cooling, heating and power balance and power rotation reserve constraints with uncertain variables are expressed as chance constraints in this paper. And they are solved by transforming them into corresponding clear equivalence classes. Besides, under the electricity market time-sharing tariff policy, a scheduling model of grid-connected microgrid combined cooling, heating and power system is established, which considers both the economy and environmental protection of dispatching and the benefits of cooling and heating. The multi-objective processing method based on satisfaction index takes into account economic and environmental goals. Finally, an example is given to illustrate the validity of the model by analyzing the micro-power output plan and the corresponding dispatching scheme of cooling, heating and power loads.
