Nghiên cứu áp dụng thuật toán PSO tối ưu vận hành hệ thống đa hồ chứa thủy điện trên lưu vực sông Đà

Abstract

The multi-reservoir hydroelectric system within the same river basin has a hydrological, hydraulic, and irrigation relationship. The operation of any reservoir affects other reservoirs, so optimal operation requires considering the simultaneous operation of all reservoirs. The problem of operating a multi-reservoir system is very complex because it involves many variables and non-linear relationships. Purely mathematical methods cannot solve it because of the large number of combinations and computing resources. The PSO algorithm is an intelligent search algorithm that can find the overall optimal solution to the problem of a multi-reservoir system. This paper presents an application of the PSO algorithm to compute the operation of a four-reservoir system for regulating flow in the Da river basin, including the Lai Chau, Ban Chat, Son La, and Hoa Binh reservoirs
