中文摘要：
提出一种应对不确定运行环境的电力系统运行协同的区间有功优化潮流模型,该模型充分发挥频率调节效应的作用以在决策层面上挖掘系统消纳不确定性的运行协同能力,并有效考虑机组备用响应过程,从而明确备用为谁而备,实现调度与控制的友好衔接;模型中不确定量和状态变量均以服从区间分布的随机变量来表示,且以仿射算术形式表达。为简化问题求解规模,给出约束缩减方法,基于强对偶理论采用互补形式表达以提取主导约束,将该模型转化为确定性的非线性规划问题,并基于GAMS平台进行求解。算例分析验证了所提方法消纳不确定性的有效性以及适应大规模系统求解的计算效率。
英文摘要：
A model of synergetic interval optimal active power flow of power system operation is proposed to deal with the uncertain operating conditions,which fully uses the frequency regulation effect to exploit the system capability of operational synergy for accommodating the uncertainties of power system operation at the decision level and effectively considers the process of unit reserve response for determining the reserve demander to realize the friendly interface between dispatch and control. The uncertainty variables and status variables in the model are described as the random variables obeying the interval distribution and treated in the affine form. Based on the strong duality theory,the complementary constraints are applied to extract the dominant constraints for reducing the solution size to convert the model into a deterministic non-linear programming problem and solve it on GAMS platform. Case analysis verifies its effectiveness in uncertainty accommodation and efficiency in solution calculation for large-scale power system.
