摘要
在Alvarado提出的电力市场动态模型的基础上,考虑需求方和供应方需求弹性的不确定性,利用区间动力系统的相关理论,建立电力市场区间模型,给出了各需求弹性区间稳定的判定条件,然后利用矩阵区间稳定性理论,运用线性矩阵不等式的工具,将需求弹性稳定区间扩大.同时给出了具体的定理及求解算法.以电力市场具体数据为例进行分析,结果表明,在模型稳定的基础上,通过本文得到了更大的需求弹性区间,为更好地控制电力市场稳定性提供了理论依据.
On the basis of dynamic model of power market proposed by Alvarado, the uncertainty of demand elasticity is considered. The power market interval model is proposed with the theory of interval dynamical systems. The determination condition for the interval stability of demand elasticity is presented. The stable interval of demand elasticity can be expanded using the linear matrix inequality tools with the stability theory about interval matrices. The details of theorem and algorithm are introduced. Based on power market example, we obtain a wider demand elasticity stable interval. The result provides theory basis for controlling the power market stability.
