Transmission Expansion Planning with variation in Load under Deregulated Environment: An Analytical Approach

In a new environment of power system, planning of transmission corridor is a major decision making issue for power engineers and transmission planning is done separately that has to be capable and robust enough to respond to uncertainties in the generation and load patterns. Hence, the accurate solution of the transmission expansion problem is essential in order to plan power system in an economic and efficient manner. There are a number of techniques that have been proposed for transmission expansion planning. These approaches and algorithms are used successfully on a very wide variety of electrical power system problems. In this paper an analytical approach is proposed which gives an optimal solution for transmission expansion planning in terms of number of line needed while expanding the corridor for transmission lines. Proposed approach is used with a thought of MW mile method in mind which works under deregulated power system.
