中文摘要 | 在本論文中,應用有灰色區間限制條件的線性規劃法在動態發電分配的問題上。 所考慮的調度問題包含在不確定負載下發電機組的最佳發電量,及發電機組發電提昇率的限 制及系統備轉容量的需求。此法的特點是將預測負載的不準確性考慮進來,以灰數表示,此 法優於傳統方法是在於傳統方法並未將負載的預測誤差考慮進來。在不確定的環境下,去得 到最佳發電調度。灰色模型將負載、備轉容量及成本以灰數表示法來表示。此法已成功的應 用於某一系統上,由結果顯示,此法能有效的解在不確定條件下之動態發電分配問題。 |
英文摘要 | An approach using linear programming based on grey constrained interval is applied to solve the dynamic generation allocation problem. This paper considers generation allocation problem that involves the dispatch of system generation optimally among generating units while tracking an uncertain load curve and observing power rate limits of the units, system spinning reserve requirements. A characteristic feature of this approach is that the error in the forecasted loads can be taken into account by using grey number notation, making the approach superior to the conventional linear programming method in which the loads are assumed to be exactly known and there exist no errors in the forecasted loads. To reach an optimal generation allocation under the uncertain environment, a grey linear programming model in which the loads, the spinning reserve requirements are all expressed in grey number notations is developed. The developed grey linear programming approach is applied to dispatch the generation in a sample system. It is found that the presented approach is very effective in obtaining proper generation allocation in uncertain conditions. |
