The power system should ensure safe and consistent to the customer. For secure operation, voltage be within desired limits, or else it will result in collapse losses. more competent, economic, reliable, reduce losses if stability is enhanced. Since determined by reactive of network, a source provided safeguard system. This paper presents enhancement using Genetic Algorithm (GA). GA approach use...

This paper proposes an efficient approach for the computation of voltage stability margin (VSM) in a large-scale power grid. The objective is to accurately and rapidly determine the load power margin which corresponds to voltage collapse phenomena. The proposed approach is based on the impedance match-based technique and the model-based technique. It combines the Thevenin equivalent (TE) networ...

A huge power is dissipated in distribution systems as power losses. The loss reduction and bus voltage improvement are the critical parameters of effective distribution feeder power flow.

Abstract With power grid heavy-load operation, and remote transmission distance which leads to voltage collapse, the method that combines continuous power flow (CPF) and improved differential evolution (IDE) algorithm is put forward to calculate a static voltage stability margin. First, we introduce mathematical model and CPF for solving the static voltage stability margin. And then, simulated ...

Bias Temperature Instability (BTI) causes significant threshold voltage shift in MOSFET using Hafnium-dioxide (HfO2) High-k dielectric material. Negative BTI and Positive BTI are two types of BTI effects observed in p-channel and n-channel MOSFET. BTI affects the stability and reliability of conventional six transistor (6T) SRAM design in nano-scale CMOS technology. Eight transistor (8T) and Te...
