The evolution of advanced inverter-based resources (IBR) is closely coupled with the growth of their applications in electric power networks. Most applications of inverters during this transition were grid-following (GFL) inverters. As IBRs gradually displaced rotating synchronous generators in electric power grid applications, issues such as the behavior of low-inertia grids, local needs for voltage support, and ride-though requirements led to the first interconnection requirements. The initial DER standard, IEEE Std 1547-2003, had to be adapted to the new context and led to the revised standard, IEEE Std 1547–2018 and later the IEEE Std 2800–2022 for transmission IBR systems. In this article, the various inverter operating modes and functions of modern inverters are described. A focus on the comparison of GFL and grid-forming (GFM) inverters based on a more comprehensive white paper developed by the SCC-21 Task Force on Advanced Inverters supporting industry standards is needed in the next few years to reduce system-wide IBR events on the electric system.
- Alternative Way to Develop Small-Signal Models of Power ConvertersThe small-signal model of a switch-mode power converter is a useful tool in understanding its dynamic behavior and designing a proper compensator. In the power electronics community, people derive small-signal models almost always by perturbation and then extracting the small ac components manually from the whole system equations. This process is not systematic and potentially… Read more: Alternative Way to Develop Small-Signal Models of Power Converters
- Proposing a Duty Cycle Based Repetitive Drain Overvoltage Specification for GaN HEMTsTransient voltage overshoot is a common phenomenon in wide bandgap (WBG) power semiconductors due to high frequency and fast switching applications. An application driven repetitive transient off-state overvoltage datasheet specification is desired for design engineers. In this work, a 1% duty-cycle-based overvoltage specification is proposed by estimating the total lifetime before the dynamic RDS( on)… Read more: Proposing a Duty Cycle Based Repetitive Drain Overvoltage Specification for GaN HEMTs
