Dynamic Transmission Network Expansion Planning

Gopi D. Dhole, M. D. Khardenvis

Abstract: The Transmission Network Expansion Planning (TNEP) problem is a large-scale, complex and nonlinear combinatorial problem of mixed integer nature where the number of candidate solutions to be evaluated increases exponentially with system size. The accurate solution of the TNEP problem is essential in order to plan power systems in both an economic and efficient manner. Therefore, applied optimization methods should be sufficiently efficient when solving such problems. In recent years a number of computational techniques have been proposed to solve this efficiency issue. In this paper genetic algorithm is presented to solve the problem of dynamic transmission network expansion planning. Subsequently, reliability assessment is performed with security constraints to evaluate and reinforce the resultant expansion plan from Genetic Algorithm.
