[Abstract]:Due to the influence of many factors, such as the increasing scale of the system, the increasingly fine dispatching requirements and the increasingly complex set of constraints, how to quickly formulate a reasonable power generation dispatching plan is a key scientific problem faced by the joint operation of hydropower stations. It is mainly reflected in three aspects: the quick generation mechanism of initial solution, the scientific identification model of decision space and the effective optimal scheduling method. For this reason, from the point of view of engineering practicality, a uniform stepwise optimization method for solving the problem of joint peak-shaving operation of hydropower stations is proposed. In this method, the potential power generation capacity of hydropower stations is estimated according to the daily operating conditions of hydropower system, and the initial solution is generated quickly by load shedding method from upstream to downstream. Then the multi-stage decision problem is decomposed into several two-stage sub-problems, and the uniform test design is coupled into the set of decision variables to guide the algorithm to select a few representative decision variables. The computational complexity of the method is greatly reduced by reducing the amount of computation and storage, and at the same time, the multi-complex running constraints are integrated into the specified constraints in the optimization process to dynamically identify the feasible search space, thus reducing the computational cost of the algorithm. The engineering application results show that the proposed method can quickly obtain satisfactory dispatching results and can effectively serve the development of hydropower dispatching operation.
