| 摘要: |
| 进行考虑输配协同的电网机组组合与技改计划联合优化，对于提高输配整体新能源消纳率、保障系统中短期可靠经济运行具有重要意义。分别构建输电网、配电网的机组组合与技改计划联合优化模型。针对中短期优化中新能源随机性较大的问题，采用机会约束规划进行处理并将约束转化为确定性约束。分析输配分立式优化、集中式协同优化、分布式协同优化求解模型的可行性，综合比较后采用基于目标级联分析法的分布式协同优化算法实现模型的输配解耦与并行求解。算例分析表明，所提模型能够合理安排输配电网的机组启停机状态及技改项目的施工计划，并验证了目标级联分析法对于解决输配协同优化问题的有效性。 |

| Abstract: |
| The joint optimization of power grid unit commitment and technical transformation plan considering transmission and distribution coordination is of great significance to improve the overall renewable energy consumption rate of transmission and distribution and ensure the medium-and short-term reliable and economic operation of the system. The joint optimization models of unit commitment and technical transformation plan of transmission network and distribution network are constructed respectively. Aiming at the problem of large randomness of renewable energy in medium-and short-term optimization, the opportunity constrained programming is adopted to transform the constraints into deterministic ones. The feasibility of discrete optimization, centralized collaborative optimization and distributed collaborative optimization of transmission and distribution is analyzed, and the distributed collaborative optimization algorithm based on objective cascaded analysis method is used to realize the transmission and distribution decoupling and parallel calculation of the model after comprehensive comparison. Case analysis shows that the proposed model can reasonably arrange the unit start-up and shutdown states of transmission and distribution grids and the cons-truction plan of technical transformation project, and the effectiveness of target cascaded analysis method in solving the transmission and distribution collaborative optimization problem is verified. |
