AI Technical Summary

Technical Problem

Among the existing methods for allocating the joint dispatch gain of cascade hydropower stations, the single index method and the coefficient of variation method cannot meet the preconditions for the allocation of joint dispatch gain. The alliance breakdown tendency method and the MDP method have problems such as lack of evaluation indicators and difficulty in determining a reasonable allocation ratio in practical applications, which makes it difficult to allocate the joint dispatch gain fairly and reasonably.

Method used

The power generation is calculated using a cascade hydropower station joint generation and dispatch model. An objective function is constructed and an initial allocation scheme is generated using a stepwise optimization method. The optimal allocation scheme is then determined by iterative optimization of the GND(i) index using the geometrically normalized alliance breakdown tendency method, which satisfies the benefits of members, the consistency of total amount, the guarantee of alliance subset benefits, and the numerical constraints of allocation ratio.

Benefits of technology

It has achieved a fair and reasonable distribution of gains among cascade hydropower stations, ensuring that each station receives fair compensation benefits, optimizing the distribution process of gains in joint dispatch, and improving the economic efficiency of power generation.

Abstract

The invention provides a cascade hydropower station combined dispatching gain quantity optimal distribution method, and relates to the technical field of power system operation and control. The method provided by the invention comprises the following steps: respectively calculating the generating capacity of a power station independent scheduling mode and an alliance cooperation mode by adopting a cascade hydropower station combined power generation scheduling model, and generating a combined scheduling gain amount; constructing an objective function based on constraint conditions of joint optimization scheduling benefit distribution of cascade hydropower stations, and generating an initial distribution scheme meeting the constraint conditions by adopting a step-by-step optimization method; iteratively optimizing the initial allocation scheme based on a GND (i) index of a geometric normalization alliance fracture tendency method to determine an optimal allocation scheme; and calculating the optimized joint scheduling gain amount based on the optimal allocation scheme. According to the method, reasonable allocation of the joint scheduling gain amount is realized by optimizing the allocation proportion through the geometric normalization alliance fracture tendency method.
