Research on Integrated Energy System Based on Thermal Power Plants Integration and Performance Evaluation
In this paper,a set of energy system with thermal power plant as the core,which absorbs renewable energy and provides integrated energy service of cold,hot,electric and steam is established.Through the analysis of the thermal performance of the whole system and key subsystems,the effectiveness of the proposed model and method is verified.The influence of some key operating parameters on the comprehensive performance is studied to demonstrate the proposed model's validity and superiority.The results show that by changing the parameters on the source side of the thermal power plant,the output on the load side of the integrated energy system can be improved.The influence of biomass gasification on the power generation of steam turbines is the greatest.The heat pump load increases with the feed water flow into the system.Part of the extraction steam in the steam turbine is used to drive the heat pump system.Although the power generation decreases by 10.88%,it provides users with heat load of 16.8 MW,the cooling load of 16.2 MW and the steam volume of 27.78 t/h.
