Research ArticleOpen accessIn the author namesApplication of the Ant Colony Search Algorithm to Reactive Power Pricing in an Open Electricity MarketA. Ketabi, A. Ali BabaeeDeveloping an accurate and feasible method for reactive power pricing is important in the electricity market. In conventional optimal power flow models the production cost of reactive power was ignored. In this study, the production cost of reactive power was comprised into the objective function of the OPF problem. Then, using ant colony search algorithm, the optimal problem was solved. … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,265 accessesView PDF Cite

Research ArticleOpen accessIn the author namesA New Method for Optimal Harmonic Meter PlacementA. Ketabi, S.A. HosseiniIn this research, a new method based on Singular Value Decomposition (SVD) is proposed to solve the problem of optimal placement of meters for static estimation of harmonic sources in a power system. Also, the Binary Genetic Algorithm (BGA) is used to solve the problem of optimization. IEEE 14-bus test system is provided to validate the measurement placement algorithm. It … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,185 accessesView PDF Cite
