Bidirectional Converters for V2G & G2V Operation

Abstract

Due to continuous rise in annual global temperature, environmental pollution, depletion of fossil fuels and petroleum products it is the need of the hour that technology like Electric Vehicle(EV) rescues and limits the risk to be aggravated over a period of time. Since 1880, the total ocean and land temperature has risen at an average pace of 0.07°C (0.13°F) every decade; however, the average rate of increase since 1981 (0.18°C / 0.32°F) has been 0.18°C (0.32°F) which is more than twice as great which is alarming situation for human race. In last few decades’ rapid urbanization has taken place which has added pressure on already existing transportation system and eventually lead to more no of vehicles on road and hence more pollution. Then there is case of security of nation because country like Australia are totally dependent on other countries for their demand of crude supplies which can affect their nations security so countries like Australia is aggressively pushing for Electric Vehicles production manufacturing and usage. In Norway the sales of Electric Vehicles were accounted for 50% of the total sale of automobiles in 1st half of the year 2020.There are many countries in the world which are pushing for stringent rules and regulations by 2030 so that more and more use of Electric vehicles is there. Coming to the developing country like India which is one of the largest power producer and consumer in the world. In such developing and hugely populated country still the power demand is not met during peak hours and hence many states go for power cuts to meet such demands. According to the studies carried out Indian power sector is facing at least power shortage varying from 2-17% in peak hours. These problems can be dealt with installation of new power plants. But such installations will need huge capital investment along with time constraints which itself will take long duration for installation and running of the plant. Additionally, after installation of such plants during off peak period we need to accumulate or store the power generated. This is where V2G (vehicle to grid) technology comes into the picture and there is another area of research that is V2H (vehicle to home) where the energy taken from grid can be used for domestic use. With this all this point in consideration market for EVs in future holds a great scope.
