Research Of Daily Generation Scheduling Based On Dynamic Programming Method And Different Bid Curve

The development and execution of generation scheduling is the key in electricity market.After comprehensive understanding of the optimal theory of daily generation scheduling.Thispaper carries out the research based on the improvement of dynamic programming and thepractical meaning of different bid curve. The details are as follows: (1)After finishing analyzing the disadvantages of average-bid-price in the form of periodof time or the whole day to solve unit commitment problem, the paper raises the method ofsynthesis-bid-price to reduce the state of unit. it has been proved through the simulation. (2)This paper analyzes the problem of local refined dynamic programming, and gives outthe range of load-optimizing and the method to choose pace. If the minimum power sect islarger than the step--length in certain speed, then the last step-length is the former. In theopposite, the last step-length is the latter. (3)Calculation and academic analysis indicate that, it can not be impartial, and can notrealize the destination of minimizing the cost for power at the same time, when electric powercompanies take decrease-model bid curve and V-model bid curve which belongs tofluctuant-model bid curve.
