Abstract
This paper deals with a new isolated wind hydro
hybrid generation system employing one squirrel-cage induction
generator (SCIG) driven by a variable-speed wind turbine
and another SCIG driven by a constant-power hydro turbine
feeding three-phase four-wire local loads. The proposed system
utilizes two back-to-back-connected pulsewidth modulationcontrolled
insulated-gate-bipolar-transistor-based voltage-source
converters (VSCs) with a battery energy storage system at their
dc link. The main objectives of the control algo ....etc

Usefulness of DC Power Flow for Active Power Flow Analysis



I. INTRODUCTION
STATIC power system analysis has always been
performed using full power flow. It is one of the
fundamental tools for power system analysis and is used in
the operational as well as planning stages. Vertically
integrated companies have used it to control their systems, as
well as to plan the optimal economic operation of generation
resources, either by means of optimal power flow or unit
commitment. ....etc

ppt on a battery less rfid remote control system

This paper presents a novel eco-friendly batteryless remote control (RC) system based on a multi-RF identification (RFID) scheme. The proposed RC device does not require the use of batteries or other installed power source. Instead, it relies on passive RFID chips that are remotely powered by an RFID reader. The controlled device (e.g., a TV) incorporates an RFID reader to power up and communicate with the RC. The proposed batteryless RC is composed of an antenna, a plurality of N passive RFID c ....etc

Data acquisition system project is a fine combination of analog and digital electronics. This project is designed so as to fulfill the requirements of the industry applications, home applications. The project consists of parameters monitoring, parameter storage. PC interface is one of the main features of the project in which various data like value of parameters, date and time are sent to the PC.

We have used Microcontroller as a main component of the project. Now a Microcontroller has become a main component of many of the electronic circu ....etc

The reason why electric cars aren t everywhere is simple at the end of their range, they have to be stationary for hours while the batteries are recharged.

This is a pity, because even cars recharged from dirty power stations are three times more environmentally friendly than conventional vehicles. That s because only 20 per cent of the energy from gasoline or diesel actually reaches the wheels; in an electric car, it s 60 per cent.

What recharging does is to change the state of the electrolyte fluid in the batteries. Now a Dutch go ....etc

Abstract

A Vanadium-Vanadium Redox battery can improve Photovoltaic system performance, reliability and robustness by increasing the energy conversion efficiency of the battery to 87%, by making the battery life, efficiency and ongoing energy capacity independent of state of charge and load profiles and by reducing maintenance requirements. High battery efficiency reduces the required PV while a battery life insensitive to battery usage relaxes system constraints. These advantages are utilised in a demonstration PV system in Thailand that wa ....etc

The VRB-ESS is a device that is capable of storing
energy in multi megawatt ranges for durations that range from hours to
days, from any available input source such as Grid, Renewable resources
or even from a diesel generator. The stored energy can then be provided
back into the Grid or supplied to a load as required & directed. It
is uniquely capable of being charged as quickly as it was discharged.
This seminar presents the various features & applications of the
VRB and discusses its future in the coming years.The
vanadium redox flo ....etc

Abstract

It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
It is the focus of this thesis to discuss the first step toward re ....etc
