This study has been undertaken to investigate the determinants of stock returns in Karachi Stock Exchange (KSE) using two assets pricing models the classical Capital Asset Pricing Model and Arbitrage Pricing Theory model. Voltage Stability is the ability of a Power system to maintain an acceptable power throughout all the buses in the power system under normal condition and after experiencing a perturbation in the power network. A power system undergoes voltage collapse if the post disturbance equilibrium voltages near loads are below acceptable limits. Voltage collapse may be total or partial. The jacobian matrix becomes singular at the voltage stability limit. As a result conventional load flow algorithms may have convergence problems at the operating conditions near the stability limit. The continuation power flow analysis overcomes the problem by reformulating the load flow equations so that they remain well conditioned at all possible loading conditions. A salient feature of the so-called continuation power flow is that it remains well-conditioned at and around the critical point. The continuation method of power flow analysis is robust and flexible and suited for solving load flow problems with convergence difficulties. The static voltage stability analysis using continuation power flow method has been carried out on IEEE 6-Bus Test System using MATLAB and PSAT software’s and results are presented.
