—A new evolutionary algorithm known as the shuffled frog leaping algorithm is presented in this paper, to solve the unit commitment (UC) problem. This integer-coded algorithm has been developed to minimize the total energy dispatch cost over the scheduling horizon while all of the constraints should be satisfied. In addition, minimum up/down-time(More)
—Most current regulations allow small-scale electric generation facilities to participate in distributed generation (DG) with few requirements on power-purchase agreements. However, in this paper, it is shown that distribution companies can alternatively encourage DG investors into DG contracts that can significantly benefit the utility network. In this(More)

These loads bring about power quality phenomena such as voltage and current harmonics, current unbalance and flicker in(More)
In this paper we present a combinatorial scheme based on hidden Markov models (HMM) and wavelet transform (WT) to discriminate between magnetizing inrush currents and internal faults in power transformers. HMMs are powerful tools for transient classification which compute the maximum likelihood probability between training and testing data signals for(More)
The paper reports on a study in which the power loss, energy loss, and loss factor were measured in an actual distribution network in Iran (Qazvin Power Distribution Company) by using an innovative method of load estimation before evaluating five ways of approaching the problem from the point of view of operating costs. The objective function was to(More)
