Non-deterministic approaches to deal with Uncertainties in Transmission Expansion Planning under Deregulated Environment Manoj Nair * and Yogendra Kumar**

ABSTRACT: The global trend for the deregulation of the power sector has led to significant changes in system planning, management and operation. The optimum approach to transmission expansion planning (TEP) in this environment is an open problem. The objectives, constraints and the approaches should be carefully designed to ensure system reliability as well as to cater the market environment. The paper presents the non-deterministic approaches, adopted in most relevant literature available, to deal with uncertainties in TEP under deregulated environment
