# 不同类型水电站群优化调度模型的大系统分解协调法研究Research on Large-Scale System Decomposition and Coordination Method for Optimal Dispatching Model of Different Types of Hydropower Stations

Abstract: According to the characteristics of different types of hydropower stations such as cascade and parallel hydropower stations, and mixed hydropower stations, the optimal dispatching model with the largest generating capacity was established. The model considers the influencing factors such as hydraulic connection and power connection between hydropower stations. A large system decomposition and coordination algorithm was used for the optimal scheduling model of different types of hydropower stations. The problem decomposition, coordination algorithm and convergence conditions were described and deduced respectively. A large-scale system decomposition and coordination model of three-stage cascade hydropower station considering the influence of the flow rate between the steps and the power connection was established, taking the Shuibuya, Geheyan and Gaobazhou hydropower stations in the Qingjiang River basin as an example. The proposed method is more efficient than the traditional algorithm, which can provide reference for the complex parallelization of the inter-provincial provinces in the large watershed, the construction of the multi-objective optimal dispatching model of the hybrid hydropower station group, the problem decomposition, and the algorithm.
