Research And Application On Short-term Optimal Dispatching Of Cascaded Hydropower Plants Of QinJiang

With a real world example of the optimal dispatching of qinjiang cascaded hydropower plants, in theories and practices this dissertation, which focuses on the management and control problems of short-term cascaded hydropower plants optimal generation dispatching in power systems in details, points out a series of ameliorated methods and approaches about traditional progressive optimality algorithm. After that, some optimized results and analyses are showed at large. The main works are outlined as the following: 1.The actuality and method of short-term cascaded hydropower plants optimal generation dispatching.2.Three kinds of optimality algorithms with the characteristic of successive approximation methods in order to resolve mathematic model,such as DDDP, DPSA and POA is introduced.3.Combining concrete datas and restriction condition of qinjiang river, the maximam benefit model of short-term optimal dispatching is built.steps to solve this model is given. 4.Combining concrete datas and restriction condition of qinjiang river, this dissertation uses POA to resolve the objective to maximize the benefit production on short-term optimal dispatching about cascaded hydroplants, giving concret account step and flow chart, adopt object-oriented method to program and then analysis and sums up these computing results.5.In the end, it summarises the work and the problems for further are discussed.
