Solar thermal generation and wind power generation complementary operation system

Abstract

The invention provides a solar thermal generation and wind power generation complementary operation system. The system comprises a wind power generation subsystem, a wind power heat supply subsystem and a solar thermal generation subsystem, the wind power generation subsystem is used for converting wind energy to electric energy and sending the electric energy to a power grid or the wind power heat supply subsystem, the wind power heat supply subsystem is used for converting electric energy initiated by the wind power generation subsystem to heat energy and sending the heat energy to the solar thermal generation subsystem, and the solar thermal generation subsystem is used for converting the heat energy to electric energy and sending the electric energy to the power grid. Compared with the prior art, according to the solar thermal generation and wind power generation complementary operation system, the electric energy generated by wind power generation is stored by employing the heat storage capability of solar thermal generation, the controllability of the wind power is improved, the wind-power grid connection performance is enhanced, and fluctuation of the wind power can be suppressed.

Description

technical field [0001] The invention relates to a power generation operation system, in particular to a solar thermal power generation and wind power generation complementary operation system. Background technique [0002] In recent years, people's demand for energy is increasing, and the power grid, as an important energy transmission system, has played an inaccessible role. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. [0003] Wind power is different from conventional power sources. Wind power stations are mostly located in remote areas and need to b...

Problems solved by technology

However, the power fluctuation range of wind power generation is large, and it is very random, intermittent and uncontrollable.

The connection of wind farms to the power grid increases the uncertainties of the power operation system and affects the power supply quality of the power grid
