| 摘要: |
| 安全约束经济调度是提高电网运行可靠率，实现节能减排，提高调度计划精细化管理水平的有效技术手段。现有安全约束经济调度研究多集中在常见目标与约束建模以及优化算法等方面，较少考虑实际生产因素，因此计划结果执行率偏低，安全约束经济调度在实际生产中实用化困难。针对上述问题，针对计划编制的优化目标，“三公”调度、计划出力曲线形状以及基础数据区间处理等实际需求，提出了基于实用化的安全约束经济调度扩展模型。将所提的建模策略应用于多个生产实例，证明了所提模型在增强“三公”调度准确率、改善计划出力曲线形状以及提高计划结果执行率上有着较好的工程实用性。 |

| Abstract: |
| Security constrained economic dispatch is an effective technical means to improve the power grid reliability rate, achieve energy-saving and emission reduction, and improve lean management of dispatching plan. Existing security constrained economic dispatch studies focuse on common goals and constraints modeling and optimization algorithm, with less consideration of actual production factors, so the planned result is of low implementation rate and security constrained economic dispatch has practical difficulties in the actual production. In response to these issues, for planning optimization goals, impartial and open power dispatching, shape of the planning output curve and basic data interval processing, this paper presents an extended model of security constrained economic dispatch based on utility. Proposed modeling method is applied to multiple production instances, which proves that the proposed model has engineering practicality in strengthening impartial and open power dispatching accuracy and improving plan output curve shape and the implementation rate of the planned results. |
