Study on optimization of multi-energy coupling system based on natural gas,geothermal energy and solar energy
Based on the combined cooling,heating and power system,ground-source heat pump,photovol-taic and photo-thermal coupled multi-energy coupling system,this paper constructs a full-condition optimi-zation model of the multi-energy coupling system,taking the comprehensive indicators of energy,economy and environment as the optimization objectives,and taking the rated capacity of the gas turbine,the key value to determine whether to operate the gas turbine,the ratio of ground-source heat pump energy supply to building load,photovoltaic area and photo-thermal area as the optimization variables,Based on the opera-tion strategy of preferentially meeting the building heat demand,the optimization model is optimized by particle swarm optimization with the constraints of the system cooling,heating and power balance and e-quipment capacity.The optimization model proposed in this paper is applied to a hotel building in Beijing,and the optimal equipment capacity and operation strategy of the optimized system are obtained,which pro-vides a reference for the optimization of the multi-energy coupling system.
