Abstract: The proposal of double carbon goal has prompted the transformation of our energy structure, and the energy revolution continues to deepen. In order to improve the economic operation level of power supply and adapt to the new transformation of the development of energy system, the low-carbon economic operation strategy of cogeneration power supply including photovoltaic access is put forward. The low-carbon economic operation strategy model of the power supply including photovoltaic, heat pump, electric energy storage device and flexible load is constructed. Aiming at the lowest daily operating cost and daily carbon emission control cost of power supply, Yalmip toolbox and Cplex solver are used to solve the established model in Matlab environment. Taking a power supply station in Beijing as an example to analyze the operation conditions under different scenarios, the results show that the proposed strategy reduces the daily operation cost and carbon emission of the power supply station, and helps to promote the peak cutting and valley filling and photovoltaic consumption of the power supply station.
