A Comparative Study Of Preventive Security-Constrained Optimal Power Flow

Security-constrained optimal power flow (SCOPF) is a vital analysis tool in power system operations and electricity markets. This paper presents a comparative study for OPF and SCOPF between two packages: a nonlinear programming algorithm in MATLAB and a successive linear programming in PowerWorld Simulator. Different OPF/SCOPF cases are implemented in the two packages and the results are compared. The reasons for the different results between the two packages are identified and PowerWorld's application in OPF is also discussed.
