Islanding Detection and Over Voltage Mitigation using Wireless Sensor Networks and Electric Vehicle Charging Stations

An islanding condition occurs when a distributed generation (DG) unit continues to energize a part of the grid while said part has been isolated from the main electrical utility. In this event, if the power of the DG exceeds the load, a transient over voltage (TOV) will occur. The adverse effects of TOVs and islanding require that sub-circuits within a power grid not only allow the detection of islanding and TOVs, but also mitigate the over voltages while having the ability to disconnect DG from the grid, if necessary. This paper proposes a solution to this problem based on wireless sensor networks (WSN) and the use of electric vehicle (EV) charging stations as their central communication hubs. Using a simulation, EVs connected to the charging stations are fast-acting loads for the mitigation of TOVs.
