Abstract

The invention discloses a solar-coal contribution degree evaluation method and an electric power distribution system of a solar-coal complementary power station in the technical field of electrical power system new energy power generation and electric power distribution. The system comprises a solar side device and a thermal power side device, wherein the solar side device and the thermal power side device are connected with a decentralized control sub-system respectively. The system further comprises a solar-coal contribution degree evaluation sub-system, a cloud resource center, a grid company distribution sub-system and a power plant centralized control room, wherein the decentralized control sub-system, the solar-coal contribution degree evaluation sub-system, the cloud resource center and the grid company distribution sub-system are connected with the power plant centralized control room in sequence. The method includes the steps of obtaining basis data, computing solar power generation quantity in different methods, and determining final solar power generation quantity according to computation results and schemes. The solar-coal contribution degree evaluation method and the electric power distribution system provide full and accurate reference for making grid purchase price subsidy policies of the solar-coal complementary power station.

Description

technical field [0001] The invention belongs to the technical field of power system new energy power generation and power deployment, and in particular relates to a light-coal contribution degree evaluation method and a power deployment system of a light-coal complementary power station. Background technique [0002] For a long time, the use of fossil fuels by humans has caused problems such as environmental pollution and climate warming, which makes the status and role of renewable energy such as solar energy in the existing energy structure increasingly obvious. If solar energy is combined with coal-fired power stations, the advantages of high parameters, large capacity, and wide adjustment range of coal-fired power stations can be used to save steam turbines and other systems in solar thermal power stations, so that the power station has good economy and achieves energy saving and reduction. row purpose. The solar-coal complementary power station can better weaken the im...
