基于负荷可行域的可靠性约束机组组合模型及其两阶段求解方法
A reliability-constrained unit commitment model based on load feasible region and its two-stage solution method
摘要
Abstract
Power system reliability evaluation is highly complex and time-consuming,making it challenging to apply within short-term operational timescales.To enable power system operation that accounts for reliability,a reliability-constrained unit commitment(RCUC)model and its two-stage solution method are proposed based on load feasible region model.First,a load feasible region model is employed to formulate reliability constraints,enabling the integration and quantitative evaluation of system reliability during the unit commitment process.Then,a two-stage solution method is developed for the RCUC model to achieve efficient computation.Finally,case studies are performed in the IEEE30 and IEEE RTS-96 systems.The results demonstrate that the proposed RCUC model can effectively reduce the total operational costs,and the two-stage solution method can accurately and efficiently obtain the optimal unit commitment scheme.关键词
