Composite Security Assessment of Uncertain Power System Considering Interaction and Response
摘要
Abstract
Along with the advancement of current smart grid construction,the characteristics of flexibility and interaction of power system have become more obvious.The uncertainties and interaction caused by the access of renewable energy and active load have brought more challenges to power system security assessment.To solve this problem,a novel method of uncertainty security assessment is proposed.Firstly,composite security indices are developed based on the theory of Hyper-box and Hyper-ellipse space.Secondly,according to the indices,the probabilistic load flow solved by Latin hypercube sampling is combined with the security assessment.By means of Latin hypercube sampling,the composite security indices are calculated in the variable operation states of power systems.Finally,the composite security assessment information can be easily obtained by statistical technology and interval numbers ranking method.Simulations show that the algorithm is able to take into account the probability distribution of power system security indices,reflect the security level of power systems suffering uncertainty of renewable energy,as well as interaction and response of the active load,providing an effective index for selection of active load”s benign interaction.关键词
