Abstract

This paper presents a hybrid algorithm using a hybrid firefly and particle swarm optimization (HFPSO) algorithm to determine the optimal placement of STATCOM devices. A multi-objective function is used to increase voltage stability, voltage profile and minimize overall power losses of the transmission system. At first, PSO algorithm is used to find the optimal STATCOM location and further more to reduce the power losses and voltage profile enhancement to overcome the sub-optimal operation of existing algorithms, the HFPSO algorithm is used to determine the optimal placement of STATCOM FACTS device and verification of the proposed algorithm was achieved on standard IEEE 14-bus and 30-bus transmission systems in the MATLAB environment. Comprehensive simulation results of two different cases show that the proposed HFPSO demonstrates significant improvements over other existing algorithms to enhance voltage stability and reducing active and reactive power losses in an electrical power transmission systems.

Abstract

This work proposes the possible implementation of a water cycle algorithm (WCA) optimized controller of tilt-integral derivative plus filter (TIDF) for the load frequency control (LFC) of a multi-area multi-fuel (MAMF) interconnected power system network (IPSN). The MAMF network has two areas, and the dynamic analysis of the IPSN is assessed pertaining to the step load perturbation (SLP) of 10% in area 1. However, the performance efficacy of the TIDF is demonstrated and validated with other recent control techniques reported in the literature. The IPSN is considered with the communication time delays (CTDs) as the realistic constraint, and their subsequent impact on the LFC performance is demonstrated and vindicated. Further, the IPSN model of the MAMF system is enacted with the battery energy storage (BES) in areas 1 and 2, and the thyristor-controlled series compensator (TCSC) with the tie-line as the territory regulator. Simulation results showcased that there will be an improvement in the LFC of MAMF system performance with the employment of a territory control scheme.

Abstract

This paper presents performance analysis of power distribution system using distribution test bench. Distribution system is the part of power system in which significant portion of the power is utilized in it. The losses occur in distribution system mainly due to inherent characteristics of the number of components in the system. In this wok, we analyse the performance of distribution system having 4 feeders having different lengths supplying resistive and combination of resistive and inductive loads. The analysis includes the voltage regulation, power loss, efficiency for different loading conditions. Also shown are the improvement of terminal voltage of the feeders and receiving end power with compensation. Finally the inferences are drawn and suggestions are proposed to improve the performance.

Abstract

This paper works on the modelling of solar PV with series parallel connection of the strings for the composite climate location and the detailed study has been done on the gate signal of the chopper used for boosting with three different conditions. As the climate conditions are very important factor for the installation of the project to fulfill the captive requirements, a study has also been done with the help of climate consultant software so that the radiations capacity and potential to develop the energy is with in its maximum output capacity. In the next phase an inverter has also been connected for the conversion into single phase AC output for the testing of the model for the usage in the load or grid. Various methods for the control of the booster has been analyzed and considered. Simulation is done on a Matlab software and the result is analyzed.

Abstract

The scheduling techniques have been investigated by the job execution process in a system to maximize multiprocessor utilization. Dynamic Power Management (DPM) and Dynamic Voltage and Frequency Scaling (DVFS) represent two general strategies for lowering energy use. Performance enhanced Scheduling (PeSche) is a proposed scheduling algorithm designed for an optimal solution. CodeBlocks were utilized to run extensive simulations. In terms of computing performance (average waiting time and average turnaround time), the PeSche scheduling algorithm outperformed recently reported scheduling algorithms such as SJF, RR, FCFS, Priority, and SJF-LJF. The PeSche scheduling algorithm yielded better results by assigning priority in terms of energy-time ratio, programming running time, total energy, and total time than existing algorithms. In comparison to Minimum Energy Schedule (MES) and Slack Utilization for Reduced Energy (SURE), PeSche consumed less energy.
