Optimal management becomes crucial for the intégration of pumped-storage to distribution Systems. In this paper, a Dynamic Programming (DP)-based approach is provided to optimally manage the opération of pumped-storage hydro-electric System. The DP adaptation to the hourly optimization problem is described, considering the constraints of water flow rate limitations , water consump-tion, minimal and maximal water levels, desired water level, electricity tariff, time period, etc. Two cases are discussed: Pumped-storage hydro-electric System and Hybrid pumped-storage wind-hydro-electric System. DP-based optimization helps make a séquence of décisions to achieve the maximum overall gained profits each day, meanwhile, the System could ensure the water supply for local résidents. Comparative results for différent opération régimes of both the fixed speed and variable speed are provided in the end.
