• Description:
  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.
