Optimal power flow analysis using Lévy flight spider monkey optimisation algorithm

Optimal power flow OPF is the most requisite tool in the power system analysis. The OPF is relatively a difficult constrained optimisation problem and broadly solved by conventional as well as modern intelligent methods. In this paper the authors proposed a Levy flight spider monkey optimisation LFSMO algorithm to solve the standard OPF problem for IEEE 30-bus system, which is proposed to improve the exploitation capability of spider monkey optimisation SMO algorithm. The performance of LFSMO is evaluated by testing it over 25 benchmark functions.
