Integrated energy electrothermal joint simulation system considering cost

Inhalt:
In order to realize the complementary and mutually beneficial use of multiple energy sources, establishing a comprehensive energy system has become a topic of wide concern worldwide, so it is necessary to develop a simulation system that can realize the coordinated operation of multiple energy flows. This paper first describes the basic content of the integrated energy simulation,a system planning model is proposed, finally, the transient system simulation program TRNSYS software was used in the case analysis.To build a specific park.Its modules can be simulated for various thermal problems.Through the combined application of various equipment in the park, simulation of the ambient temperature and soil temperature, the resulting thermal network system can be jointly simulated with a microgrid system containing distributed energy sources, joint Simulation of heat grid containing solar collector-air source heat pump-heat storage tank-heat pump and power grid containing photovoltaic array-wind power generatorenergy storage system, thus, the domestic water and electricity consumption of the park are simulated. Finally, the system cost is the lowest optimization goal. The proposed method can provide a reference for electrothermal interconnection operation and planning.
