Study on the decision support system for optimal operation of cascaded hydropower plants in local power network

In order to meet the need of local power optimally allocating its cascade hydropower plants, a decision support system for optimal operation of local cascaded hydropower plants is studied and designed out in this paper. The functions of the system include data management, hydrological forecast, long-time optimal operation alternative, short-term optimal operation alternative 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.
