Transient Over-Voltage Mitigation and its Prevention in Secondary Distribution Networks with High PV-to-Load Ratio
Recent report of utility providers have shown that under certain conditions the integration of renewable energy sources might cause damaging transient over-voltages (TOVs) in the power grid. TOVs are short, rapid rises in voltage along the electric lines of the grid that can occur when the generated power of a distribution circuit exceeds its load while the circuit is isolated. The described scenario can cause permanent damage to utility equipment or personal electric household devices. This report introduces various methodologies that can mitigate TOVs in distribution networks, or reduce the probability of their occurrence.
