Abstract

The increasing penetration of EVs on LV Distribution networks can potentially cause voltage quality issues. Smart decentralized charging controls for EVs that aim to mitigate under-voltages and voltage unbalance, rely only on local voltage measurements. Due to this situation, the simultaneous reaction of all EV charging controls can induce voltage oscillations in the network, which leads to an unstable operation of the system. Three mitigation strategies have been applied to the most relevant decentralized charging controls to eliminate voltage oscillation. Results show that most of the strategies are able to diminish and eliminate voltage oscillations when implementing an EV decentralized charging control in a LV network. The most suitable mitigation strategy depends on the selected charging control, and on the topology of the network.
