Contingency analysis has been considered as critical issue in power systems because it initiates failures transmission line and failure equipment. Hence, this paper is presented Red Deer Algorithm (RDA) to manage contingency condition for improving security of the system. The proposed algorithm utilized solve Optimal Power flow (OPF) with multi-objective functions. function consisting six singl...

Together with quality power supply criteria, Composite Power System (CPS) reliability is also one of the important aspects deciding security CPS for a given load demand. In current paper, evaluated. The Newton Raphson (NR) approach implemented in Simulation Engineering (PSSE) software to take into account, flows, then available points, evaluate CPS. NR Method was by considering different contin...

The stability and security improvements of the grid-connected to wind energy conversion system (WECS) can be made by optimizing placement a flexible alternating current transmission (FACTS). This study discusses optimal one type WECS, namely doubly-fed induction generator (DFIG) with series shunt-FACTS control device called unified power flow controller (UPFC). DFIG UPFC connected grid dynamic ...

<p>Flexible alternating current transmission system (FACTS) devices are deployed for improving power system’s stability either singly or as a combination. This research investigates hybrid FACTS and studies their impact on voltage, small-signal transient simultaneously under various disturbances. The simulations were done using five devices-static var compensator (SVC), static synchronous...

Comprehensive unified power flow controller ( UPFC ) technology can calculate voltage control parameters of UPFC, but it increases the nonlinearity Newton calculation. When comprehensive is combined with intelligent algorithm, only be optimized through active and reactive on branch, which makes optimization convergence worse. Therefore, an optimal calculation method for distribution network bas...
