A comprehensive model for stochastic load flow analysis in electric power systems is proposed for the purpose of estimating the statistics of bus voltage magnitudes, circuit currents and transmission line power flows. The proposed method is driven by a realistic nonconforming stochastic electric load model, defined in terms of few independent stochastic processes; it is based on the quadratized...

The ordinary power flow or load flow problem is stated by specifying the loads in megawatts and megavars to be supplied at certain nodes or busbars of a transmission system and by the generated powers and the voltage magnitudes at the remaining nodes of this system together with a complete topological description of the system including its impedances. The objective is to determine the complex ...

The optimization is one of the challenging problems in power system. The optimization sometimes is mainly restricted to the minimization of the operating cost. However, the operation of power plants, mostly thermal units, results into various types of emissions like SOx, NOx and COx etc. The environmental concern dictates the minimization of the emissions by the thermal plant. Individually, if ...

The capacity of renewable distributed generation (DG) connected in distribution networks is increasing. Use power electronic interfaces means DG can inject harmonic currents through the point common coupling into upstream networks. limits stipulated emission standards may create challenges for accommodating DG. To explore impact regulations on ability to host DG, this work incorporates voltage ...

due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...
