In this article, an efficient moth swarm-based optimal power flow (OPF) methodology is addressed. Three objectives are considered such as minimizations of (i) total fuel cost of production units including effects of valve ripples, (ii) emission rate, and (iii) network real power loss. Set of operating constraints are adapted considering production units’ prohibited zones to emulate real analysis along with security aspects. The moth swarm optimizer (MSO) is employed to generate the best values of the specified design continuous and discrete control variables. Two test cases viz. IEEE 30-bus and 57-bus networks are demonstrated under various scenarios. The simulations are performed under MATLAB environment. Numerical simulations, subsequent discussions and appropriate comparisons to other methods indicate the viability of the proposed MSO-OPF tool. At last, the compulsory performance measures are made to confirm the observed performance of the MSO algorithm in solving OPF problem.
