面向电力系统充裕度风险的多类型负荷侧灵活调节资源全场景安全调度方法
All-scenario-feasible Economic Dispatch for Heterogeneous Demand-side Flexible Resources Towards Adequacy Risks of Power Systems
摘要
Abstract
Under the"dual carbon"goals,the growing integration of renewable energy into power systems imposes greater demands on operational flexibility.Demand-side flexibility resources,which are widely distributed,exhibit rapid response capabilities,and offer strong economic feasibility,have the potential to deliver ample regulatory capacity for power systems.However,existing studies primarily focus on single-resource scheduling,lacking in-depth exploration of the coordinated operation of multi-type resources and their role in ensuring system adequacy.To address this issue,an all-scenario secure scheduling method for multi-type demand-side flexible resources was proposed to mitigate power system adequacy risks.First,a generalized model for heterogeneous demand-side flexibility resources is developed based on their operational characteristics.Next,the impact of renewable energy output variability on system adequacy is examined,and a two-stage forward-looking rolling optimization method is proposed,incorporating implicit decision rules and scheduling security domains through critical scenarios and all-scenario feasibility constraints.Numerical validation is performed on an enhanced IEEE 30-bus system.Results show that the proposed method reduces total load shedding from 9.512 0 MW to 1.650 5 MW compared to methods without security domain constraints,significantly enhancing system adequacy and operational flexibility.关键词
