Regulatory developments include FERC''s actions on electric storage resources participating in the wholesale markets, co-location of large electric loads, qualifying facility eligibility,
New US regulations for grid-tied inverters, set to take effect in January 2026, mandate advanced functionalities for grid support, safety, and cybersecurity, requiring manufacturers and
Explore NERC''s new standards for inverter-based resources and their implications for grid stability, renewable integration, and business strategies in the evolving energy landscape.
The North American Electric Reliability Corporation ("NERC") has taken an important step in implementing revised reliability standards for inverter-based resources ("IBRs").
Developed by the North American Electric Reliability Corporation (NERC), the standards address critical issues regarding IBR performance and require IBRs stay connected to the grid during
Why do we need Grid-forming (GFM) Inverters in the Bulk Power System? There is a rapid increase in the amount of inverter-based resources (IBRs) on the grid from Solar PV, Wind, and Batteries.
In this context, this paper proposes a comprehensive control and system-level realization of Hybrid-Compatible Grid-Forming Inverters (HC-GFIs)- a novel inverter framework designed to
This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization.
On Novem, the Federal Energy Regulatory Commission (FERC or Commission) issued a Notice of Proposed Rulemaking (NOPR) that focuses on reliability issues related to the growth of
If set to non-unity, reactive power will be injected or (typically) absorbed at times when it is not needed placing an unnecessary reactive power burden on the utility system and generator.
