Dispatch Function And Future Electricity Decomposition Research In Cascade Hydropower Station

This paper established cascade dispatch function step-regression algorithm.Through time,space and energy factors screened,the dispatch function is brief and with well explanation.Comparison with certainty optimized result showed its efficiency and feasibility; when applied in Jinshajiang -Changjiang River system it reflects high simulate precision, which provided a feasible path for optimized operation.In order to meet the demand of participating in power market,this paper proposed cascade power division and decomposition model while participating in annual future market based on cascade operation feature,and acquired the division and decomposition result.The decomposition results can assure each station accomplish future contract in a high guarantee rate,as well as set aside relatively even bidding space which is benefit for the market operation,thus achieved fine production and practical efficiency.
