Optimal regulation control system for cascade hydropower stations

A complex optimal regulation control system with three-layer structure is developed for cascade hydropower stations, including from top to bottom optimal regulation control layer, automatic water regime measuring and generation supervisor layer, economical dispatching control and automatic generation control layer. After three optimal rules of maximum generation, maximum energy reservation, and minimum level violation are analyzed, three corresponding mathematical models are established. Based on the analysis and application of different optimization algorithms, the advanced dynamic programming is suggested to be used in optimal regulation control of cascade hydropower stations. Applications in the Wu River have demonstrated that optimal regulation control can greatly improve economic benefit and management level. Other cascade hydropower stations that are carrying out or will carry out optimal regulation control can use the experience for reference.
