摘要
针对大规模风电反调峰特性和空调负荷等因素造成的系统负荷高峰谷差给电网安全、经济运行带来的挑战,在分析商业、工业负荷移峰潜力的基础上,设计了用户侧自愿申报用电意愿和移峰成本的新型用户侧互动模式。基于该互动模式,建立了能够充分反映用户意愿的用户侧互动负荷模型,并将其嵌入传统的安全约束机组组合模型中,提出了发用电一体化调度计划模型。实现了用户侧互动负荷作为可调度资源参与电网运行,减少了高成本机组启停,降低了系统运行成本。新英格兰39节点系统验证了所提出的模式和模型的有效性。
In view of the challenge by the system peak-valley difference due to the large-scale wind power anti-peak-regulation characteristic and air-conditioning load to both the economy and security of power system operation,a new interactive mode of voluntarily declaring power consumption willingness and peak-load shifting cost is designed.The interactive mode is based on an analysis of load shifting potential of commercial and industrial customers.Based on this mode,a load model of interactive customer fully reflecting customer willingness on the customer side is developed.A generation and load integrated scheduling model is built by embedding the load model of interactive customer into the traditional security constrained unit combined model.The load model of interactive customer can participate in power network operation as scheduling resources,reducing the cost of expensive generator start and stop as well as the operation cost of the power system.New England 39-bus system validates the effectiveness of the proposed mode and model.
