To solve maximum loadability limits problem, various techniques are available in the literature In earlier years conventional methods based on continuation power flow [1] and Interior Point method for non-linear and sequential problem were developed [2,4-7]. Few authors modified the interior point algorithm to solve the problem when zone-based constraints are imposed on the loads [8]. While few authors calculated the nearest bifurcation point from an interior or an exterior point of the feasible region [12-13]. Some authors solved the problem by optimal adjustment of generation and load under constraints and treated the problem as an optimal power flow problem [14-15].
