Problems solved by technology

[0003] However, there is a strong coupling relationship between the electric energy and heat energy generated by the combined cooling, heating and power unit, and the user's demand for electric energy and heat energy is relatively random, and it is usually difficult to effectively match the two; in order to achieve "energy supply-energy" balance , most combined cooling, heating and power systems have problems such as low unit operation efficiency, low comprehensive energy utilization efficiency, and high energy cost

Abstract

The invention provides a control method for a combined cooling, heating and power supply system including an electrothermal composite energy storage device. Electric system discharge, heat storage system heat storage, heat storage system heat release and other steps. The control method proposed in the present invention is based on the control principle of increasing the operating load rate of the combined cooling, heating and power unit, improving the utilization rate of the energy storage system, and making full use of the low electricity price, combined with the power and capacity limitations of the power storage device and heat storage device, to The energy distribution of the system is optimized and managed, thereby improving the operating efficiency and energy utilization efficiency of the unit, reducing the operating cost of the system, and effectively promoting the application of electric heating composite energy storage technology in the actual combined cooling, heating and power supply system.

Description

technical field [0001] The invention belongs to the field of distributed systems, and in particular relates to a control method for a combined cooling, heating and power supply system including an electrothermal composite energy storage device. Background technique [0002] Combined cooling, heating and power system (CCHP) is the most common application method of distributed systems. The combined cooling, heating and power unit is used as the main energy supply equipment, and combined with the power grid and gas pipeline network, it provides users with three energy sources: electricity, cooling and heating at the same time. . Since the CCHP system is close to the user, while the cogeneration unit generates electric energy, the waste heat can also be recovered by the recovery device to provide the heat energy required by the user. Therefore, cascade utilization of energy can be realized, the energy efficiency of the system can be improved, and environmental pollution can be r...
