The usage of energy storage units in power system will reduce frequency oscillations immediately subjected to random load changes. In this project, investigations are carried out for an isolated power system with ALFC unit and isolated power system with mutual coupling effects. In each case the effect of different storage units are studied for random […]
The voltage source inverter fed induction motor drive produces pulsating torque due to harmonics present in the output voltage of the inverter. Therefore reduction of harmonics is the major concern in any power converter fed ac drives. In this paper, a harmonic reduction technique for four pole induction motor drive is presented. A modified carrier […]
This paper investigates the dynamic performance and the stability of synchronous reference frame phase-locked loop (SRF-PLL) influenced by microgrid and network-side parameters. Given that the stability of PLL affected by microgrid-side parameters has not been yet studied, this article aims at evaluating this issue after a detailed analytical modeling of microgrid components (including the production […]
This article presents a network reconfiguration in balanced distribution networks using Multi Verse Optimization (MVO) to optimize the total system resistive losses and reduce emissions by means of step by step switching. Reconfiguration is a considerable manner of altering the power flows through the lines from the main substation to load ends, while maintaining radial […]
This paper objective presents static synchronous series compensation FACTS device with biogeography based optimization (BBO) to deal for obtaining worthwhile power flow control. The biogeography based optimization method is utilized to find the optimal fitted child sets by surviving parents with the help of migration and mutation process. The present BBO technique from the evolutionary […]
Hybrid Energy Storage System (HESS) has been implemented for better energy efficiency to Hybrid/Electric Vehicles (HEV/EV), in that the main source is Battery and UltraCapacitor (UC) is the auxiliary source. The battery is connected to DC Bus through Boost Converter and UltraCapacitor has connected through Buck-Boost Converter. Battery and UltraCapacitor voltages levels are maintained less […]
This paper includes a novice technique for locating single line to ground fault in electrical transmission network. Validation of the proposed algorithm is demonstrated using matlab simulink. Simpower system tool box is used for the modeling of smart meter, transmission lines and single line to ground fault (1L-G). A novel method is proposed to countercheck […]
Sentiment analysis automatically classifies the opinions, which are expressed in a document, usually as positive or negative. A review document in general, reflects its author’s opinion about the objects mentioned in the text. Therefore, it can have many useful applications such as opinionated web search and automatic analysis of reviews. Although sentiment analysis is a […]
Wireless sensor networks (WSNs) contains an enormous number of sensor nodes deployed in huge numbers which are able to sense, process and transmit environmental data to the base station for plenty of applications. Clustering is one of the important issues for prolonging the network lifetime in wireless sensor networks. It includes grouping of sensor nodes […]
Interline power flow controller (IPFC) is a concept of AC flexible control of the transmission system (FACTS), with the ability to series compensation and power flow management in multi lines of a post power. Out of all FACTS devices interline power flow converter (IPFC) is considered to be the most flexible, powerful and versatile. IPFC […]
