Electric boiler energy storage control method suitable for frequency modulation and deep peak regulation

Abstract

The invention discloses an electric boiler energy storage control method adaptive to frequency modulation and deep peak regulation, which comprises the following steps of: selecting frequency modulation and peak regulation modes, selecting manual and automatic control modes, accurately processing and distributing unit load instructions, distributing and controlling loads of energy storage units, and performing interlocking start-stop and switching on the energy storage units. The unit peak regulation auxiliary service energy storage unit is interlocked to start, stop and switch, flexible start and stop control over the electric boiler energy storage and heat storage system is achieved, electric boiler energy storage participates in frequency modulation and deep peak regulation of the thermal generator set, and the automation level and regulation control performance of the energy storage and heat storage system are improved. According to the electric boiler energy storage control method adapting to frequency modulation and peak regulation, the automation level and the regulation control performance of an electric boiler energy storage and heat storage system are improved, and the working intensity of operators is reduced; the requirements of the power grid frequency and load are effectively met, the stability of the power grid frequency is ensured, and the safe operation of the power grid is ensured.

Description

technical field [0001] The invention relates to a control method, in particular to an electric boiler energy storage control method adapted to frequency regulation and deep peak regulation, and belongs to the technical field of automatic control of power generation systems. Background technique [0002] In order to effectively solve the overcapacity of electricity, promote the consumption of clean energy such as wind power and photovoltaics, and realize the improvement of the flexibility of coal-fired power plants, some thermal power plants in China are equipped with electric energy storage boilers, which use the power that cannot be accepted by the grid during the heating period of coal-fired heating units Heating energy storage, and realize external heating, improve the external heating capacity of coal-fired heating units. Make full use of energy storage, change the traditional operation mode of coal-fired heating units through electrothermal conversion, and at the same t...
