Abstract

The invention relates to a system and a method for saving energy and shaving the peak by coordinating a cogeneration set and a wind energy generator set. The system comprises the cogeneration set, the wind energy generator set, a conditioner heat pump, an electric energy meter, a radiator, a heat consumption gauge, and a scheduling control device, wherein the scheduling control device is used for acquiring fuel consumption, generated output and heating output of the cogeneration set, generated output of the wind energy generator set, electric power consumption of heating of the conditioner heat pump, a scheduling control signal of the heating load of the radiator in the electric load trough period according to detected electivity consumption data and heating and heat consumption data, and controlling the cogeneration set, the wind energy generator set, the conditioner heat pump, and the radiator to run according to the scheduling control signal. Through the system and the method, the distribution of the generated output of each of the cogeneration set and the wind energy generator set is optimized so as to reduce the total energy consumption, save energy and solve the problems of the forced shutdown and the waste of abandoning electricity of the wind energy generator set in the electric load trough period of the power grid.

Description

technical field [0001] The invention relates to a combined heat and power energy supply system, in particular to a system and method for energy saving and peak regulation of a combined heat and power unit cooperating with a wind energy generator set. Background technique [0002] The existing power grid includes two power generation modes: one is to provide electric energy solely from the power generated by the combined heat and power unit, and the other is to provide electric energy solely from the power generated by the wind power generator set. These two generator sets operate independently. Among them, the combined heat and power unit supplies electric energy to end users and provides heating energy at the same time. However, wind power generators can only provide electrical energy to end users, and heat energy needs to be supplied by another thermal energy plant. [0003] The physical state of cogeneration unit operation is limited by the operating condition map of "p...
