The research of united optimal operation aid decision system for cascade hydropower plants in local power network

The decision-making support system for optimal operation of cascaded hydropower plants in local electric power network, which includes system structure build up, and module design methods, is studied and designed in order to satisfy the demands of cascade hydropower plants optimal management in local electric power network. The system function include data management, hydrological forecast, long-time optimal operation planning, short-term optimal operation planning, and daily operation scheming. The system can provide decision support for optimal operation of small cascade hydropower plants in local power network. The system is applied in one local power network, and the results show that it is efficient.
