摘要: |
为快速有效地求解考虑间歇性可再生能源接入的SCUC问题,在现有约束序优化的基础上,提出了一种适用于不确定性SCUC问题求解的改进约束序优化算法。该方法针对序优化的粗糙模型和精确模型分别融入了离散变量识别策略和无效安全约束削减策略。相比于传统求解方法,提出的改进约束序优化算法在充分发挥传统序优化计算效率方面优势的同时,进一步增强了算法的紧凑性,降低了计算冗余度,有效提升了算法的求解效率。基于IEEE-118节点标准算例的仿真验证了所提算法的正确性和有效性。 |

Abstract: |
For the sake of solving the Security Constrained Unit Commitment (SCUC) problem of intermittent renewable energy access quickly and effectively, an improved ordinal optimization algorithm which can be applied to solve the uncertain SCUC problem is proposed on the basis of existing constrained ordinal optimization. In order to solve the crude model and precise model, discrete variable identification strategy and effective security constraint reduction strategy are respectively adopted. Compared to the traditional method, this modified ordinal optimization algorithm gives full play to the traditional ordinal optimization in computational efficiency while further enhances the compactness and reduces the computation redundancy. The correctness and effectiveness of the proposed algorithm are verified by the IEEE-118 simulation results. This work is supported by National Natural Science Foundation of China (No. 51607104). |
