Influences on dispatch of power generation when introducing electric drive vehicles in an Irish power system year 2020

Increased focus on global warming and CO2 emissions imply increased focus on the energy system, consisting of the heat, power, and transport systems. Solutions for the heat and power system are increasing penetrations of renewable heat and power generation plants such as wind power and biomass heat plants. For the future transport system, electric drive vehicles are expected to be one of the solutions. Introducing different electric drive vehicle penetrations in a power system with a large amount of wind power, changes the usage of the predefined power system. This work presents investigations of different charging regimes’ influence of the power dispatch in the Irish power system. Analyses show an overall cost decrease and CO2 emission increase in the heat and power system with the introduction of electric drive vehicles. Furthermore, increased intelligence in the electric drive vehicle charging results in larger decrease of overall cost and smaller increase in CO2 emissions. With the charging regimes presented in this analysis, the cost decreases range from 23.2M€ to 165.5M€, whereas the increase in CO2 emissions are in the range 1.16Mton to 0.69 Mton.
