To optimize the operation of combined heat and power supply integrated energy system

this paper introduces a new type of phase change heat storage electric heater

and establishes an optimization model including photovoltaic

fan

micro gas turbine

heat storage electric heater and energy storage battery. The model aims to increase the consumption of new energy and reduce the operating cost of the system

which uses the mixed linear integer programming method to solve the problem with YAMLIP toolbox and CPLEX. By comparing the operation modes of the combined heat and power supply integrated energy system in two different scenarios

the feasibility and economy of the proposed model is verified

and the feasibility of the new equipment in enhancing thermal and electrical coupling is explored. The results show that

the combined heat and power supply integrated energy system with heat storage electric heater can effectively reduce the cost

and the thermal inertia of the heat storage heater can play a good role in shifting peaks and increasing the consumption of renewable energy.
