Abstract

The invention discloses a method and a system for optimizing scheduling for short-term combined generation of a cascade reservoir group. The method comprises the following steps: S1) establishing and storing two short-term optimizing scheduling models, namely, a maximum cascade generating capacity model and a maximum cascade energy storage model, by a scheduling server; S2) selecting a short-term optimizing scheduling model according to a generating optimizing target by the scheduling server; S3) collecting model solving materials by a data collecting device, and selecting an algorithm for solving the short-term optimizing scheduling model by the scheduling server; and S4) generating and outputting a short-term generating scheduling optimizing scheme by the scheduling server. According to the method provided by the invention, the benefit and the speed are both considered while an optimizing scheduling model for a cascade hydropower station and a solving algorithm are searched, and the optimal optimizing scheduling scheme for the short-term combined generation of the cascade reservoir group is achieved.

Description

technical field [0001] The invention relates to a cascade reservoir group short-term combined power generation optimization dispatching method and system, belonging to the cascade reservoir group power generation optimization dispatching field. Background technique [0002] The short-term power generation optimization dispatch of cascade hydropower stations is a very complex system engineering problem. Its core is to establish an optimal dispatch model that can fully reflect the physical characteristics and operating mechanism of the system on the basis of fully considering the constraints of short-term dispatch hydraulic power and electric power. Find a model solving algorithm that meets the requirements of scheduling timeliness and rationality. The short-term dispatch cycle is shorter and closer to the actual operating conditions of the reservoir hydropower station. Its task is to determine the operating status of each hydropower station or the power grid in the next sche...

Problems solved by technology

Since the short-term power generation optimization dispatch of cascade hydropower stations involves many constraints such as the power station itself and unit output distribution, load vibration area, grid load transmission and PSS, and even requires 15 minutes as the long dispatch period, this greatly affects the calculation efficiency of the model and algorithm and the plausibility of the results
