Reactive Power Optimization using Particle Swarm Optimization with Time Varying-Acceleration Coefficient
Abstract: This paper presents an approach for the solution of reactive power optimization problem. In deregulated power system operations, reactive power optimization helps the system operator to maintain system security with the economy. The application of the time-varying acceleration constant-particle swarm optimization (TVAC-PSO) method for the solution of this problem is emphasized. The real power losses of the system are minimized satisfying power balance, generator reactive power operating limit and voltage …

A Pragmatic Approach of Managing Maximum Power Demand with Generator Control Mechanism Using PIC Microcontroller
Abstract: Maximum power demand management is an embedded based project which may be enforced in industries wherever quantity of active load on the idea of critical and non-critical have to be monitored and controlled. Industries are required to use a private controller to dominate these individual parameters. The aim of this project is to use one controller for distributing power from multiple feeders in sequence, just in case of load overflow …

Effects of Supply Voltage on 6T CNT Based Schmitt Trigger
Abstract: In this growing and developing age of technology, we are needed to improve our methods in order to get better results. So taking this into account, in electronic field, we want circuits with low propagation delay, leakage current and leakage power. So, we compared the model of Schmitt trigger using C-MOS (Complementary mosfet) and CNT (carbon nanotube) technology. We performed the variation in power supply (varied from 0.1to 1.2 V) …

Optimal Generation Rescheduling for Congestion Mitigation using New Variant of Derivative Free Optimization Method
Abstract: Proposed work describes the process of rescheduling active power generation to alleviate transmission congestion in a most economic manner considering all the system constraints. Most severe line outage has been considered as the congested line using LODF factor. The concept of GSF has been used for selection of generators to be rescheduled for congestion management. Time-Varying Acceleration Constant-Time-Varying Inertia Weight Particle Swarm Optimization (TVAC-TVIW PSO) based optimization algorithm has been …
