This paper presents an AC Optimal Power flow (AC-OPF) problem of a powersystem, considering wind energy. Wind energy is an environmental-friendly energy source to produce electrical power and it includes lessoperating costs compared with other sources of electrical power production. Wind generatorsalso affect the operation costof a power system as well as transmission losses,based on generators locations and speedof wind. In addition, wind speed is a parameter with uncertainty and considering this uncertainty is an important issue in operation of wind generators in the AC-OPF problem. The proposed AC-OPF formulation includes the integer variables in addition to continuous variables and studiesthe effects of wind energy, transformer tap settings, and shunt capacitors on fuel cost, transmission lossesas well asup and down spinning reserves. To solve the AC-OPF model, an Improved Particle Swarm Optimization (IPSO) is presented. The IPSO algorithm in this work includes velocity mirror effect that causes improvement in the quality of the results. The proposed method is appliedon modified IEEE 30 bus test system, and obtained results approve the validity and effectiveness of the proposed method.
