Problems solved by technology

However, at present, the control methods for combined generation of solar thermal power plants and wind power in China are not perfect, usually only for the optimization of single solar thermal power plant dispatching and wind farm dispatching, resulting in low utilization rate of wind energy and high abandoned wind volume; at the same time, wind farms A large number of connections will also put forward higher requirements for the stable operation of the power system

Abstract

The invention provides a method and a device for controlling the coordinated operation of a wind power and solar power complementary system. A maximum power output predication value of wind power anda maximum power output predication value of solar power are calculated at first; then wind power output dispatch instruction values and solar power output dispatch instruction values at various moments are determined through a multi-target optimization module; and then the actual power of a wind power plant and the actual power of a solar power plant in the wind power and solar power complementarysystem are controlled according to the wind power output dispatch instruction values and the solar power output dispatch instruction values at the various moments. By adopting the method and the device provided by the invention, the grid connection of renewable energy sources is promoted, the abandoned air volume is reduced, and the benefits of the grid connection are increased; the maximizing ofthe benefits of the grid connection of the wind power and solar power complementary system and the variance of the grid-connected output power are coordinated better, and the grid connection of the renewable energy sources and the friendly operation of the relative power grid are facilitated.

Description

technical field [0001] The invention relates to new energy power generation control technology, in particular to a method and device for coordinated operation control of wind power and photothermal power generation complementary systems. Background technique [0002] In order to cope with the huge pressure and new challenges brought by large-scale wind power access to the safe and stable operation of the power system, and to reduce the volatility and uncertainty of wind power generation, the operation of wind turbines needs to be equipped with large-capacity energy storage systems. However, when equipped with a large-capacity energy storage system, additional operating costs are increased. Therefore, the joint operation of wind power and economical and controllable energy has gradually become a research hotspot. [0003] With the rapid development of photothermal technology in recent years, photothermal power generation has gradually attracted people's attention. According ...
