The Stability

The small-signal stability problem of complex connected DC DPS was studied. Using mathematical induction method, it is proved that the N subsystems cascaded DPS can be seemed as two equivalent subsystems at arbitrary interface as the stability conclusion is the same. But for complex connected DPS which have M sources, it could be equivalent to M sources and one load system instead of two equivalent subsystems and M minor loop gain at M different interfaces should be satisfied Nyquist criterion simultaneously to ensure the DPS's stability.

First of the practical defiance's in unsystematized electrical networks is Congestion management. Two manners of percussions used in Congestion management are frill manners and cost free manners. In this paper work congestion is released by using cost free manners seeing (Flexible AC Transmission Systems) FACTS controller like SVC (Static Var compensator), STATCOM, TCSC (Thyristor controlled series Compensator), and SSSC (Static Synchronous Series Compensators) devices. Manifold-objective functions are presumed for congestion management. Small signal stability, voltage profile, and Real power loss reduction are considered objective functions in this paper. The optimal placement of FACTS controller are institute by using sensitivity founded Eigen value analysis and Continuation Power Flow (CPF). The suggested algorithm has used to define optimal placement of FACTS controller and deciphering optimal power flow (OPF) to advance voltage profile and minimize the real power losses within real and reactive power generation margin. The recital analysis has been implemented for IEEE 39 bus test system using MATLAB/PSAT (toolbox) software. Results display the suggested technique has a competency to advance the “Voltage profile, small signal stability, Loss minimization”.
