Summary:Uncoordinated charging of electric vehicles (EVs) using level 2 chargers, which have high power requirements (6-11kW), is a concern to power grid operators because it can lead to voltage instability. One solution to this issue is to coordinate charging scheduling. Various scheduling schemes have been proposed but discussion on the potential impact of the schemes to EV owners' comfort is very limited. This paper aims to provide insights on the degree of negative impact different EV scheduling schemes can create to EV owners' comfort (defined as being related to the EV state of charges). We demonstrate this by testing three heuristic scheduling schemes in a simulated grid operating under normal and faulty conditions. The results reflect the need for compensation mechanisms in electricity contracts where EV scheduling is imposed on EV owners.
