REVIEW ON: ENERGY STORAGE MANAGEMENT IN MICROGRID BY USING VEHICLE TO GRID TECHNOLOGY Payal jangilwar, Prof. Balram Yadav M-tech scholar, Department of Electrical and Electronics Engineering, Scope College of Engineering, BhopalHOD, Department of Electrical and Electronics Engineering, Scope College of Engineering, Bhopal ------------------------------------------------------------------------***-----------------------------------------------------------------------Abstract- Electric vehicles are gaining demand day by day. Energy storage system is important for microgrid energy management. Electric vehicles can help in energy storage system of microgrid. It can store energy by using grid to vehicle technology and can supply back to grid by using vehicle to grid technology. A proper architecture is needed to apply this technique of energy storing. To realized this concept architecture of DC fast charging for electric vehicles is developed. The level 1 and level 2 AC charging for electric vehicles can harms the distribution system, resulting in overloading of transformer, voltage fluctuations and power losses. To reduce these losses Dc fast charging is used because it reduces charging time to 2030 minutes. In this paper we will see a brief review on electric vehicles and their charging system for energy storage in microgrid.
Keywords : Vehicle to grid technology, electric vehicle, DC fast charging , microgrid, tie- grid inverter. INTRODUCTION Electric vehicles are automobile machines designed by one or more electric motors. This can draw power from an onboard source of electricity. Electric vehicles are proven to be workable solution for minimizing green house gases and most importantly global anthropogenic emissions that emerge from transportation and energy sectors. Vehicle to grid technology (V2G) technology can be explained as a system which can bear a control over bidirectional energy flow between electric vehicles and electrical grid. For microgrid energy storage system are very important and electric vehicles plays major role in it. V2G technology in general power grid faces many challenges such as difficulty in control system, requiring large numbers of electric vehicles and difficulty in implementation. In previous studies we found that, V2G technology in general power grid employs with level 1 and level 2 AC charging which is limited to on board charger’s power rating. Therefore DC fast charging architecture is introduced to charge electric vehicles which are also called as level 3 charging. It is previously proven that “level 1 charging technique uses plug to connect with electric vehicles for charging and it uses 120V input voltage.” It is very slowest process and takes long time to charge the vehicles. When it comes to level 2 charging “it uses dedicated electric vehicles supply equipment at home or at public station to provide power to electric vehicles it uses 220V – 240V input voltage and 30 A”. DC charging( level 3 charging) takes min 20-30 minutes to charge the vehicle. This paper is organized as follows: General overview of Electric Vehicles, vehicle to grid concept, microgrid and DC fast charging scheme.
1. LITERATURE REVIEW The main objective of this work is to provide precise analysis on energy storage sytsem in microgrid by V2G and G2V technology by using DC fast charging. In prious studies we got to know that” electric automobiles were being produced as early as the 1800”. It was studied that “ the technology requiring for electric car was being developed before the automobile was conceived.
The primary cell invented by volta in 1800”. It generate electricity by chemical action.
In 1833 working electric motor was invented, Thomas Davenport come up with it after observing demonstration of an electromagnet. In 1837 he patented his motor.
