基于区间不确定性的约束潮流
Constrained Power Flow Based on Interval Uncertainty
摘要
Abstract
In view of the uncertainty problem of the input data due to renewable energy injection and load changes,a new constrained power flow model based on the interval algorithm is proposed.First,the input data changes are expressed in an interval form,and then the traditional power flow equations are converted into an optimization model considering voltage and reactive power constraints.In the solving process,the interval comparative concept is introduced,and the uncertain constrained optimization problem is decomposed into two deterministic sub-problems,or the upper bound and lower bound problem. Finally,the two sub-problems are solved by the modern interior point algorithm to obtain the upper and lower bound solutions. Extensive numerical simulations on IEEE 14-bus, 57-bus, 1 18-bus systems and South China 703-bus system, have demonstrated the effectiveness and rapidity of the proposed method as compared to affine arithmetic and Monte Carlo simulation.关键词
