Nowadays, power distribution networks are focus mainly on power quality issues. Among the power disturbances, sag, swell and voltage harmonics are studied and deliberated in this research paper. These problems have negative impacts especially on the sensitive load, which have to be protected and secured against these problems. Therefore, to solve such disturbances, the series active power filter (SAPF) can be an efficient solution, which is used to compensate the voltage difference and to reduce the problem’s effects on the power system. In this paper, the SAPF is simulated and experimentally validated, where two control methods are used to control the applied disturbances; which are classical proportional integral PI and nonlinear backstepping controllers. The control structure of the SAPF aims to reduce the error of the injection voltage closed loop, in addition to reduce the total harmonic distortion (THD) values below 5% and within the specified ranges of the international IEEE-519 standard. From simulation results, the backstepping nonlinear controller has reacted more robustly and efficiently than the conventional PI controller.

A New Advanced Topology for Photo Voltaic Applications Sreedhar M; C. K. Panigrahi; Abhijit Dasgupta; J. Pati
International Journal of Applied Power Engineering (IJAPE) Vol 4, No 1: April 2015
Publisher : Institute of Advanced Engineering and Science

This article proposes a high efficient DC-DC step-up converter with a single switch. This is particularly suited for Photo Voltaic (PV) applications, automotive applications, battery operated vehicles etc., in which voltage is step up from 10V to 500V. This converter operates at 100 kHz due to which switching losses are comparatively high. This topology proposes a scheme to mitigate power losses across the switch and to achieve high efficiency by Zero Current Switching (ZCS) at “Turn ON and Turn OFF” states. Proposed converter uses a single switch to reduce the losses in the converter and observed 98% of overall efficiency in the converter. The proposed converter is verified by its experimental results.

International Journal of Applied Power Engineering (IJAPE) Vol 9, No 3: December 2020
Publisher : Institute of Advanced Engineering and Science

This paper presents an enhanced bacterial foraging optimization (EBFO)algorithm for solving the optimal reactive power problem. Bacterial foraging optimization is based on foraging behaviour of Escherichia coli bacteria which present in the human intestine. Bacteria have inclination to congregate the nutrient-rich areas by an action called as Chemo taxis. The bacterial foraging process consists of four chronological methods i.e. chemo taxis, swarming and reproduction and elimination-dispersal. In this work rotation angle adaptively and incessantly modernized, which augment the diversity of the population and progress the global search capability. The quantum rotation gate is utilized for chemo taxis to modernize the state of chromosome projected EBFO algorithm has been tested in standard IEEE 14,300 bus test system and simulation results show the projected algorithm reduced the real power loss extensively.

Publisher : Institute of Advanced Engineering and Science

Polymer properties can be experimentally tailored by adding small amounts of different nanoparticles to enhance its mechanical, thermal and electrical properties; thus, it has been widely anticipated that the combination of nanoparticles with traditional resin systems. This paper has been studied the enhancement and controlling electric and dielectric properties of low density polyethylene (LDPE), and high density polyethylene (HDPE) polymer materials by cost-fewer nanoparticles. Certain percentages of clay and fumed silica nanoparticles have been enhanced electric and dielectric properties of polyethylene nanocomposite films. Dielectric spectroscopy has been measured the electric and dielectric properties of each polyethylene nanocomposite with and without nanoparticles at various frequencies up to1kHz under different thermal conditions (20oC and 60oC). Also, it has been investigated the optimum types and percentages of cost-fewer nanoparticles for enhancing electric and dielectric characterization at low and high temperatures.

International Journal of Applied Power Engineering (IJAPE) Vol 4, No 3: December 2015
Publisher : Institute of Advanced Engineering and Science

This paper presents an efficient methodology to detect the fault occurrence and its tolerance of four switch voltage source inverter in a single Xilinx Spartan 3E Field Pro-grammable Gate Array (FPGA). The merit of this proposed system reduces the time period between fault existence and its isolation with four switches in two legs instead of six switches in three legs so as to minimize the switching losses, accuracy, and better recovery time. The FPGA platform supports the run-time reconfiguration of control functions and algorithms directly in hardware and meets hard real-time performance criteria in terms of timings for SVPWM generation, fault detection time and fault tolerance time. Simulation and Experimental results of this proposed system is demonstrated and verified.

Photovoltaic Array Modeling under Uniform Irradiation and Partial Shading Condition Lunde Ardhenta; Wijono Wijono
International Journal of Applied Power Engineering (IJAPE) Vol 6, No 3: December 2017
Publisher : Institute of Advanced Engineering and Science

Wind energy and solar energy are the prime energy sources which are being utilized for renewal energy. The performance of a photovoltaic (PV) array for solar energy is affected by temperature, irradiation, shading, and array configuration. Often, the PV arrays are shadowed, completely or partially, by the passing clouds, neighboring buildings and towers, trees, and utility and telephone poles. Under partially shaded conditions, the PV characteristics are more complex with multiple peaks, hence, it is very important to understand and predict the MPP under PSC in order to extract the maximum possible power. This paper presents the development of PV array simulator for studying the I–V and P–V characteristics of a PV array under a partial shading condition. It can also be used for developing and evaluating new maximum power point tracking techniques, for PV array with partially shaded conditions. It is observed that, for a given number of PV modules, the array configuration significantly affects the maximum available power under partially shaded conditions. This is another aspect to which the developed tool can be applied. The model has been experimentally validated and the usefulness of this research is highlighted with the help of several illustrations.

Solar Energy System Based Impedance-Source Inverter for Grid Connected System S Kamalakkannan; D. Kirubakaran
International Journal of Applied Power Engineering (IJAPE) Vol 7, No 2: August 2018
Publisher : Institute of Advanced Engineering and Science

In this work, the fickleness of solar energy can be overcome by using Maximum Power Point Tracking algorithm (MPPT). Perturb and Observation (P&O) MPPT algorithm accomplish fast the maximum power point for rapid change of environmental conditions such as irradiance intensity and temperature. The MPPT algorithm applied to solar system keep the boost converter output constant. Output from boost converter is taken to three phase impedance-source inverter with RL load and grid system. Impedance-source inverter performs the transformation of variable DC output of the solar system in to near sinusoidal AC output. This near sinusoidal AC output consecutively is served to the RL load first and then to grid system. The simulation is carried out in matlab/simulink platform both for RL load and grid system and the simulation results are experimentally validated for RL load arrangement only.

Security Constraint Unit Commitment Considering Line and Unit Contingencies-particle Swarm Optimization Mohammad Sadegh Javadi
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 1: April 2012
Publisher : Institute of Advanced Engineering and Science

This paper presents a new approach for considering all possible contingencies in short-term power system operation. Based on this new approach, both generator and transmission line outages would be modeled in network-based power system analysis. Multi generator and also parallel transmission lines is modeled in this methodology. We also investigate this claim that feasibility and applicability of this approach is much more than the previous analytical methodologies. Security Constrained Unit commitment (SCUC) program which is carried out by Independent System Operator (ISO), is one of the complex problems which would be handled by this approach. In this paper, a DC-Optimal Power Flow (DCOPF) methodology has been implemented by particle swarm optimization technique. The Lagrangian Relaxation technique is based on the derivatives and the PSO is a non- derivative technique. These approaches are effective tools which can be implemented for short-term and long-term power system analysis, especially for economic analysis of restructured power systems. The DCOPF methodology has been considered for LMP calculation in LR, which is not available in PSO techniques. In the other hand, PSO technique may be able to provide the optimal solution, where LR usually getting stuck at a local optimum in a large scale power system. The simulation results show that the presented methods are both satisfactory and consistent with expectation.

International Journal of Applied Power Engineering (IJAPE) Vol 8, No 1: April 2019
Publisher : Institute of Advanced Engineering and Science

This paper is an attempt to use the vehicle-to-grid (V2G) connected system to play an effective job in the regulation of the voltage and power of the power system besides its positive effect for the system frequency. A two area power system is used to measure the effectiveness of the proposed V2G scheme. The proposed system is tested under the step load change condition and three phase short system case. A comparison between the system with proposed V2G schemes and that system without V2Gs is carried out showing the importance of the presence of the V2G schemes on system frequency, terminal voltage and total power. MATLAB /SIMULINK software package is used as a test environment.

Automatic Generation Control of Multi-Area Power System with Generating Rate Constraints Using Computational Intelligence Techniques P. Subbaraj; K. Manickavasagam
International Journal of Applied Power Engineering (IJAPE) Vol 2, No 1: April 2013
Publisher : Institute of Advanced Engineering and Science

In a large inter-connected system, large and small generating stations are synchronously connected and hence all stations must have the same frequency. The system frequency deviation is the sensitive indicator of real power imbalance. The main objectives of AGC are to maintain constant frequency and tie-line errors with in prescribed limit. This paper presents two new approaches for Automatic Generation Control using i) combined Fuzzy Logic and Artificial Neural Network Controller (FLANNC) and ii) Hybrid Neuro Fuzzy Controller (HNFC) with gauss membership functions. The simulation model is created for four-area interconnected power system. In this four area system, three areas consist of steam turbines and one area consists of hydro turbine. The components of ACE, frequency deviation (F) and tie line error (Ptie) are obtained through simulation model and used to produce the required control action to achieve AGC using i) FLANNC and ii) HNFC with gauss membership functions. The simulation results show that the proposed controllers overcome the drawbacks associated with conventional integral controller, Fuzzy Logic Controller (FLC), Artificial Neural Network controller (ANNC) and HNFC with gbell membership functions.
