Reliability Based Impact of Inverter-Based Resource Adoption in Bulk Power System
One of the burning topics in today’s power system industry is high penetration of inverter-based resources (IBRs) and their impact on the reliability of the grid of the future. The lessons learned from the previous events occurred in the power system provide very useful insights on assessing the risks and potential mitigation schemes to address the gap between the operation of the conventional generation units and these new resources. Thus far, the majority of IBRs have been deployed based on grid following concept relying on stable frequency and voltage at the point of interconnection which requires a revisit as the pace of penetration increases and the generation mix changes rapidly.
In this presentation, the main updates made on the regulatory side from NERC’s standpoint will be reviewed and immediate needs for further updates to be made will be highlighted to address any deficiencies in the reliable operation of the IBRs in the grid of the future. Furthermore, two main recent events occurred at Texas grid will be investigated in further details based on the collaborative reports issued by the involved parties including, NERC, Texas Reliability Entity, and ERCOT. The findings from these events combined with the future updates on guidelines and standards will be discussed to provide insight on future corrective actions to be taken by system operators and generation owners towards maintaining the reliable operation of the grid.
