Clearing method, system and device for guaranteeing hydroelectric energy consumption and medium

Abstract

The invention discloses a clearing method, system and device for guaranteeing hydroelectric energy consumption and a storage medium. According to the method, based on related basic data of a power system and the power abandoning cost of hydroelectric energy in the system, a safety constraint unit combination model is established by taking minimization of the sum of the power purchasing cost and the power abandoning cost of the hydroelectric energy as a constraint target, and units in the power system are cleared according to the safety constraint unit combination model. The system comprises afirst collection module, a first processing module, a second collection module, a second processing module and a clearing module. By using the method provided by the invention, the consumption of hydroelectric energy can be increased, the utilization rate of hydroelectric resources is improved, and the environmental benefit is considered while the economic benefit of power generation is ensured; and the actual water abandoning electric quantity of the hydroelectric generating set can be effectively determined, and the accurate reliability of constraint target clearing is ensured. The method can be widely applied to the technical field of power energy dispatching.

Description

technical field [0001] The invention relates to the technical field of power energy dispatching, in particular to a clearing method, system, device and medium for ensuring the consumption of hydropower energy. Background technique [0002] In recent years, my country's clean energy industry has been developing and growing, and the industrial scale and technical level have been rising rapidly. In particular, a large number of installed and operated hydropower units have made outstanding contributions to alleviating the constraints of energy resources and the pressure on the ecological environment. [0003] The current clearing mechanism of the electricity spot market is based on the declaration information of market members and the boundary conditions of power grid operation, and uses the Safety Constrained Unit Combination (SCUC) program to optimize calculations, and the clearing results in market transactions. In short, under the premise of ensuring the safety of the power ...

AI Technical Summary

Problems solved by technology

However, this implementation method cannot guarantee the full consumption of hydropower energy, and does not take into account the energy-saving and low-carbon advantages of hydropower resources. Especially in certain flood seasons, a large amount of hydropower energy is wasted

At present, there is still a lack of a good clearing mechanism in the prior art to solve the above problems
