Review of Electric Vehicle-To-Grid (V2g) Technology
Abstract
Kinoti Emmanuel and Juma Michael
Background: Currently, Electric Vehicles are being widely adopted worldwide due to the gradual depletion of conventional sources of energy, environmental pollution, and global climate changes. Integration of Electric Vehicles in power system networks is gradually adopted. The integration is being accompanied by power stability, reliability, and quality issues. Intelligent incorporation of electric vehicles to the grid is required to address these challenges. Electric vehicles offer the potential to gradually decrease carbon emissions and offer grid supporting services such as active power regulation, reactive power support, and load balancing to the power grid. Electric Vehicles possess unique property as a dynamic load and flexible distributed energy storage device. Electric vehicle support services for the power grid act on balancing the power exchange rate and direction between the electric vehicle battery storage system and the grid. This paper provides an up – to – date comprehensive evaluation of vehicle-to-grid technologies and associated grid ancillary services that maintain power system stability and reliability.
