This paper focuses on the DC noise margin analysis and read/write failure analysis of the proposed 8T low power SRAM cell. In the proposed structure two voltage sources, one connected with the Bit line and the other connected with the Bit bar line for reducing the voltage swing during the switching activity. These two extra voltage sources will control the voltage swing on the output node and i...

The traditional control method has a low margin of indoor voltage stability, which can easily lead to collapse, and the effect is not ideal. An automatic distributed for low-voltage electricity system based on modal symmetry algorithm proposed. In order improve stability margin, decoupling between characteristics regions was analyzed. Based analysis results, robustness faults zone scheme were c...

Many power engineering systems have dynamic state variables which can encounter constraints or limits affecting system stability. Voltage collapse is an instability associated with the occurrence of a saddle node bifurcation in the equations which model the electric power system. We investigate the effect of constraints on voltage collapse by studying the effect of constraining state variables ...

This study presents a procedure for placing static var compensators (SVC) in an EPS using the fuzzy c-means clustering technique. For this purpose, optimal power flow (OPF) is initially quantified to obtain sensitivity array of system based on Jacobian system. Then, attenuation and electrical distance matrices are estimated. Subsequently, algorithm used with estimated cluster identification cri...

This paper presents an algorithm for solving the multi-objective reactive power dispatch problem in a power system. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal voltages, reactive power generation of the capacitor banks and tap changing transformer sett...

The purpose of this paper is to study the reactive power sensitivity as an index for finding out the weakest bus. Voltage Collapse point is also determined from the P-V and Q-V curves of the weakest and next weakest bus. The way of finding out Voltage Stability Margin is also proposed. Finally, a method to compensate the reactive power of the weakest bus to improve its stability is also propose...
