Social welfare maximization based optimal energy and reactive power dispatch using ant lion optimization algorithm

In this paper an optimal energy and reactive power dispatch problem is solved by using the ant lion optimization (ALO) algorithm considering total cost minimization social welfare maximization (SWM) objectives. Two different market models are proposed in work, i.e., conventional/sequential clearing proposed/simultaneous clearing. each model, two objectives, SWM considered. The conventional (SW) consists benefit function of consumers active generation. paper, SW modified including function. calculation exactly same as that practice. most important difference instead doing post-facto manner practice, simultaneous approach work. scientificity suitability methodology has been examined on standard IEEE 30 bus test system.
