Review and Prospects of Robust Transmission Expansion Planning

With integration of high proportion of renewable energy and rapid development of smart grid,uncertainties of power systems are further enhanced.The uncertainties present new challenges to transmission expansion planning.As an optimization method dealing with uncertainties,robust optimization is applied to transmission expansion planning problem,becoming an active research topic.In this paper,research on robust transmission expansion planning(RTEP)is reviewed.Firstly,recent development in RTEP area is summarized.Next,based on robust optimization theory,a RETP model of general form is proposed,and approaches of modeling uncertainties including load,renewable energy,equipment failure and generation investment and retirement are demonstrated.Finally,in order to provide guidance and suggestions for future RTEP research,prospects and challenges of RTEP are illustrated,pointing out the problems to be addressed and direction of development in future RTEP research.
