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.

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme
SINGLE LINE ....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.

http://cobberswp-content/uploads/2008/01/fillbattery.jpg

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

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 w ....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 flo ....etc
