Study on Operation Optimization Strategy of Ground Source Heat Pump Heating System

“Transform coal heating to electric heating” is an important part of the electric power alternative strategy. The electric heating has an incomparable advantage over other heating systems, which makes it widely recognized. Using ground source heat pump for electric heating brings more social and economic benefits. On the basis of studying the method for calculating the thermal load of users and the principle of chance-constrained programming (CCP), the two-layer operational optimal model of ground source heat pump system is established, which aims to minimize electricity consumption and maximize the thermal comfort. The improved PSO algorithm is used to resolve the model to obtain the optimal control strategy of ground source heat pump system and the load distributive strategy of heat pump units. The analysis of examples-, a campus heating building heating system, shows that the model and the control strategy proposed in this paper can improve the energy efficiency of electric heating system on campus and lower the cost of electricity consumption without reducing the thermal comfort. This approach is instructive and referential for the operation of electric heating system on park buildings.
