• Abstract:
  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.
