However, in order to supply heat in winter, the combined heat and power unit operates in the mode of "heat fixed power generation", and its output power cannot be reduced, resulting in insufficient peak regulation capacity of the system and poor overall regulation capacity of the power grid
[0005] During the heating period in the northern part of the country, the heating units operate "by heat to determine electricity", which leads to a serious shortage of peak-shaving capacity of the system, which cannot meet the requirements of large-scale wind power and photovoltaic power generation consumption, resulting in serious abandonment of wind and light.
[0006] There are many ways to improve the comprehensive utilization efficiency of energy and reduce the phenomenon of curtailment of wind and light, but the input cost is high. The more economical and practical method is to study the use of combined heat and power (CHP) units to improve the comprehensive Ability to accommodate new energy sources such as wind power and photovoltaics

An electric power control method for a combined heat and power unit including a heat storage tank and an electric boiler. This adjustment method aims at the limitation of the electric power adjustment of the operation mode of the cogeneration unit that "uses heat to determine power". By adding a heat storage tank and The electric boiler has changed the working characteristics of the combined heat and power system, largely untied the previous coupling relationship of "heating to determine electricity", greatly improved the load regulation capacity of the power grid, and contributed to the power grid's consumption of new energy such as wind power. capacity. The electric power adjustment method of the present invention solves the contradiction that the peak-shaving capability of the system is insufficient because the input of cogeneration units in the heating season squeezes the grid capacity of wind power and other new energy sources. Therefore, the present invention is significant.
