An Analytical Review of Multi-objective Optimal Power Flow Techniques

摘要

Power systems are becoming larger and complex with rise in electricity-demand. This increases complexity of a system for finding the optimal solution of power flow problem. Solution of optimal power flow (OPF) problem has now become necessity for electrical utilities because of the objectives of minimum fuel cost, power loss, emission and voltage deviation, which are non-convex, non-linear and non-smooth in nature. Consequently, system can cause severe damage both physically and economically if operated without any power flow analysis. This paper reviews different optimization techniques for solution of OPF problems with one or more objectives subject to balanced and unbalanced constraints.
