An Analytical Approach for DG Placement in Reconfigured Distribution Networks Sarfaraz Nawaz; Ajay Bansal; M. P. Sharma
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

A novel approach is proposed in this paper for optimal placement of DG units in reconfigured distribution system with the aim of reduction of real power losses while satisfying operating constraints. The proposed analytical method for optimal DG placement is developed based on a new mathematical formulation. Type-I and type-II DG units are used here. The results of the proposed technique are validated on IEEE 69 bus distribution system. The level of DG penetration is also considered in a range of 0–50% of total system load. A novel index is also proposed which incorporates level of DG penetration and percentage reduction in real power losses. The results are promising when compared with recently proposed algorithms.

Transient Analysis of Switching the Distributed Generation Units in Distribution Networks Mehrnoosh Vatani
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

Adding distributed Generators (DGs) to the passive electrical networks causes major changes in the specifications of the network including voltage profile, short circuit level and transient stability. In this paper, the effect of DGs switching transient in network is considered. The DGs location are changed in different buses. Two types of DGs are used (i.e. wind and synchronous DGs). Switching transient signals are time variant. It has a continuous spectrum of frequency. Fast Fourier and Wavelet transform methods are used for transient analysis. The proposed method is applied to IEEE-13 Bus distribution system.

A Multi-objective Hybrid Heuristic Approach for Optimal Setting of FACTS Devices in Power System Operation Sai Ram Inkollu; Venkata Reddy Kota
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

Improvement of power system performance in terms of increased voltage profile and decreased transmission loss is becoming one of the challenging tasks to the system operators under open access environment. Apart from traditional power flow controlling devices, use of Flexible AC Transmission System (FACTS) devices can give an attractive solution for the operation and control of deregulated power system. The type, size, location and number of FACTS devices are to be optimized appropriately in order to get the targeted benefits. In this paper, two FACTS devices, Thyristor Controller Phase Shift Transformer (TCPST) and Interline Power Flow Controller (IPFC) are selected to obtain the required performance such as improvement of voltage profile and loss minimization. To search the optimal location and optimal rating of the selected FACTS devices, a hybrid algorithm which formulated with Particle Swarm Optimization (PSO) and Gravitational Search Algorithm (GSA) is proposed. At the first step, the optimization problem is solved for finding the optimal location of FACTS devices using PSO with an objective of voltage profile maximization and later GSA is implemented to optimize their parameters with an objective of transmission loss minimization. The proposed method is implemented on IEEE 30-bus test system and from the simulation results it can be proved that this technique is well suited for real-time application.

Artificial Bee Colony Algorithm for An Optimal Solution for Combined Economic and Emission Dispatch Problem Sandeep Bhongade; Sourabh Agarwal
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

In India Electrical Energy is generated mainly Coal based Thermal Power stations and hydro Electric Power Stations. The main aim of power generating company is to provide good quality and reliable power to consumers at minimum cost. The problem of Combined Economic and Emission Dispatch deals with the minimization of both fuel cost and emission of pollutants such as oxides of Nitrogen and Oxides of Sulphur. In our power system the emission is major problem created that’s why in now a days we move from green energy source or renewable energy such as Sunlight, Wind, Tides, Wave, and Geothermal Heat Energy. The Emission constrained Economic Dispatch problem treats the emission limit as an additional constraint and optimizes the fuel cost. In this paper we optimizes the Combined Economic and Emission Dispatch problem by using two different optimization method such as Artificial Bee Colony (ABC) and Genetic Algorithm (GA).The proposed ABC Algorithm has been successfully implemented is to IEEE 30 bus and Indian Utility sixty two Bus System The simulation result are compare and found the effective algorithm for Combined Economic and Emission Dispatch problem.

Performance Analysis of 5-Phase Multi-level Inverter Using Carrier Based PWM Technique M. Lavanya; B. Jyothi
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

The major analysis has been based on the induction machine drive system that is for the analysis of the carrier based PWM two level source inverter. The unbalanced conditions are mainly to handle the results of simulation for the analysis that results in the two fault conditions. The system setup has been involving the voltage source inverter as well as the five phase multi-level inverter. The effects are through performing the scenarios which consider the performance effects with the load on induction machine. The simulation is based on the imbalance conditions which results on the oscillations depending on the electromagnetic torque through the attendant reduction of the torque rating. The larger slipping has been in the rotor speed.

A Step Down Transformerless Single Switch Integerated Buck and Buck-Boost Converter P. Maithili; C. Tharani; J. Nivedha; D. Soundarrajan
International Journal of Applied Power Engineering (IJAPE) Vol 5, No 3: December 2016
Publisher : Institute of Advanced Engineering and Science

This paper presents about the designing of the controller for integrated Buck Buck-Boost converter for maintaining the constant DC output voltage. This constant output voltage can be used for low voltage application. The absence of transformer includes the advantages of losses is less, efficient power factor and high efficiency. It provides the simple control structure with the positive constant output voltage .It operates on the closed loop with the designing of the PI controller for a MOSFET switch to provide the gate pulse. Whatever may be the input voltage it will produce the constant output voltage. The converter is successfully done by using MAT Lab/Simulink and verified the error reducing to negligible values.
