AB - In order to establish a new optimal load distribution between CHP units and  wind turbines and realize a new type of energy-saving dispatching, the  authors proposed a dispatching system based on smart grid. The author  proposed that the heat pump with electric drive air conditioning should  share part of the heating load of the hot water radiator, accordingly, the  supply of heating water is reduced, increase heating power load. This  directly leads to the increase of the total power load in the grid and the  decrease of the total heating and hot water load, changing the proportion of  thermal power load. Based on the new heating water and power load  constraints, a mathematical model of optimal scheduling is established, the  energy-saving dispatching of cogeneration units and wind turbines is  realized. The simulation results show that using the new energy-saving  scheduling method, 342.4 MWh of fuel can be saved per hour, and the energy  saving benefit is about 8.83%. If the calorific value of standard coal is  29271 kJ/kg, this means that the fuel consumption savings per hour is about  42.14 ton standard coal. The calculation results show that the higher the  value is, the more economically feasible the feed-in price of wind power is.  In conclusion based on the current electricity price and heating heat price,  in order to ensure that the economic benefits of each participant are not  changed, the feed-in price of wind power is discussed, and the economic  feasibility of the method is proved.
