NERC Releases Inverter-Based Resource Strategy Plan
October 25, 2022The North American Electric Reliability Corporation (NERC) recently released an Inverter-Based Resource (IBR) Strategy, which details the steps needed to successfully integrate IBR facilities into the planning and operation of the power system. The strategy was put in place due to the rapid interconnection of IBR systems, which are extensively used for solar and wind generating facilities, including new battery-based energy storage systems and are one of the most significant drivers of power grid transformation. Because of control system inconsistencies, IBR facilities pose well-documented risks to power system reliability when this strategy’s practices are not adhered to. NERC’s plan calls attention to the need for thoughtful integration of IBRs and identifies current and future work required to mitigate reliability risks resulting from the deployment of this technology.
