中文摘要 | 一般來說,傳統最佳電力潮流都是利用一些最佳化技巧來求解單一運轉狀態。在這 些最佳電力潮流方法中,所有可能的變數都用來求解此問題。在實際的運轉上,如此的解將 不實用,因為考慮的控制動作太多太複雜。在本文中,靈敏度因子結合動態規畫法被用來求 解短期最佳電力潮流。首先,考慮當各匯流排負載變化不一致時的兩階段實功調度法用來求 解實功調度問題。然後,靈敏度因子法用來求解無效功率的調度問題。最後,動態規畫法技 巧用來求解控制動作最小化問題。此方法的優點為簡單及容易實行,而能有效幫助運轉規畫。 |
英文摘要 | In general, conventional Optimal Power Flow(OPF) solutions utilize some optimization techniques at a single case- In the OPF solution method, all the available variables are used to solve the problem In practical operation, such a solution is not a practical consideration because the control actions would be too many to be implemented. In this paper, sensitivity factors combined with dynamic programming technique are used to solve short term (one day) dynamic optimal power flow. A two-step real time real power dispatch method considering inconforming load change is used to solve real power dispatch, and then, the sensitivity factors are used to solve reactive power dispatch with some constraints. Finally, the dynamic programming technique is used to minimize the control actions to as little as possible. The advantages of this method are simple and easy to implement. and it would greatly enhance the operators' planning. |
