In this implementation consists two single-phase to three-phase conversion systems for a three-phase load application. The load is connected to a single-phase grid through an ac–dc–ac single-phase to three-phase converter. The single-phase rectifier is composed of two parallel single-phase half-bridge rectifiers. The main objective of this design is based on number of switching devices is reduc...

Load flow (LF) study, which is performed to determine the power system static states (voltage magnitudes and voltage angles) at each bus to find the steady state operating condition of a system, is very important and is the most frequently carried out study by power utilities for power system planning, operation and control. In this paper, a radial basis function neural network (RBFN) is propos...

This paper goal to analyze the costs that are associated with the power transfer as well as the designing of new computer techniques and the allocation of these costs based on AC power flow method vs. DC power flow method. IEEE-12 bus system results are analyzed the Method based on AC power flow using distribution factors.

This paper presents a novel probabilistic optimization algorithm for simultaneous active and reactive power dispatch in power systems with significant wind power integration. Two types of load and wind-speed uncertainties have been assumed that follow normal and Weibull distributions, respectively. A PV bus model for wind turbines and the wake effect for correlated wind speed are used to achiev...

Due to the rapid technological progress, the consumption of electric energy increases continuously. But the transmission systems are not extended to the same extent because building of new lines is difficult for environmental as well as political reasons. Hence, the systems are driven closer to their limits resulting in congestions and critical situations endangering the system security. Power ...

A fundamental strategy for utilizing green energy from renewable sources to tackle global warming is the microgrid (MG). Due predominance of AC microgrids in existing power system and substantial increase DC generation load demand, development AC/DC hybrid (HMG) inevitable. Despite increased theoretical efficiency minimized AC/DC/AC conversion losses, uncertain loading, grid outages, intermitte...

Electric power industries throughout the world have been restructured to introduce competition among the market participants and bring several competitive opportunities. Open access to the transmission system places an emphasis on the intensive use of the interconnected network reliably, which requires knowledge of the network capability. Available Transfer Capability (ATC) is a measure of the ...

This paper is concerned with market-based protocols for relieving congestion caused by transactions outside the control area in which the congestion occurred. One approach, proposed by Cadwalader et al. is based on dual decomposition in which out of area congestion is “priced-out” and added to the optimal power flow (OPF) objective function of the control area operator while the prices are dete...

In this paper, a fuzzy logic controller is proposed for an application of HVDC link to stabilize the frequency oscillation in a parallel AC – DC interconnected power systems. When an interconnected AC power system is subjected to a load disturbance, system frequency may be considerably disturbed and becomes oscillatory. By utilizing the system interconnections as the control channels of HVDC li...
