Document Type and Number:
WIPO Patent Application WO/2021/164496
Kind Code:
A1
Abstract:
Disclosed is an optimal control method for photoelectric conversion efficiency of a solar/coal complementary system under variable working conditions. The method comprises: by reading relevant information of a solar heat collection system, coal-fired power generation system and the environment, and by reading operating conditions of a solar/coal complementary system, determining the heating water flow range of the solar heat collection unit and the solar/coal flow distribution ratio range that the solar/coal complementary system can operate in; and by establishing the relationship between the photoelectric conversion efficiency and solar/coal flow distribution ratio of the solar/coal complementary system under variable working conditions, adjusting the solar/coal flow distribution ratio, thereby controlling the flow of heating water into the solar heat collection system, achieving the control objective of maximizing the photoelectric conversion efficiency, and improving the economics of the solar/coal complementary system under variable working conditions. The present invention can provide clear teaching for optimizing the control of the solar/coal complementary system under variable working conditions, giving full play to the role of solar energy in the solar/coal complementary system, improving the utilization rate of solar energy, promoting the consumption of renewable energy, and greatly improving the unit economy.
