松弛约束发电计划优化模型和算法

Application of Relaxed Constraints Model on Generation Schedule Optimization

安全约束机组组合和安全约束经济调度是发电计划优化的核心,算法鲁棒性是影响其工程应用的关键因素。在对通用安全约束机组组合优化模型分析基础上,提出安全约束发电计划的松弛约束模型。通过松弛机组发电量约束、环保约束、网络约束、机组速率约束和机组调节范围约束等,提高算法收敛性能。文中所提出的模型和算法已成功应用于某省级电网。

Security constrained unit commitment （SCUC） and of generation schedule optimization, while robustness is the analysis of a general security constrained unit commitment constrained generation schedule optimization is proposed security constrained economical dispatch are the core component critical issue for its application in grid operation. Based on an optimization model, a relaxed constraints model for security Through the relaxation of energy constraints, environmental constraints, network constraints and generation capacity constraints, the convergence performance of the algorithm is rapidly improved. A day-ahead and real-time generation schedule optimization application based on the model and algorithm is presented, which proved a success in a provincial power grid.
