One kind of cascade hydropower stations jointly Orthogonal DDDP method of scheduling
2014
The present invention belongs to the field of Hydro Power Optimization scheduling discloses orthogonal DDDP method for joint optimization cascade hydropower stations scheduling, by the method of combining the orthogonal design method and DDDP to frame basis DDDP the combination between the different discrete states of each stage of each test plant were considered a problem multifactor preferred level: N N power stations are considered trials factors were taken of each plant Q discrete states corresponding neighborhood, plant different discrete state i i factors are considered different levels, a combination of the state constituting the plant considered as a discrete state protocol, the use of orthogonal composition selected from all the states have a "uniformly dispersed neat comparable" in nature portion state combination is calculated. The present invention avoids DDDP comprehensive combination algorithms between different discrete states each time all power plants, reduce computational complexity, significantly improved operation efficiency and the plant size is calculated, scheduling problem of joint optimization of the large scale hydropower systems and applications has good reference value.
