The displacement of synchronous generators with inverter-based sources in the electric grid
can results in larger frequency deviations due to lower rotating inertial energy. Existing grid …

Currently, the majority of grid-connected PV sources operate in current-control mode, which
is known as grid-following control. The ability of grid-following sources to provide ancillary …

Extensive deployment of interoperable distributed energy resources (DER) is increasing the
power system cyber security attack surface. National and jurisdictional interconnection …

Increasing penetration levels of solar photovoltaic (PV) and the reduced inertia of inverter-
based generation technologies have caught the attention of the electric power industry and …

Penetration of converter-based distributed generation units (DGUs) rises quickly in the
power systems. These generation units, which do not have any rotating masses, reduce the …

Inverter-coupled generation is slowly displacing synchronous generators in the power
system, resulting in reduced system inertia and primary frequency response, which makes …

This report describes research related to electric power system frequency support from
inverter-coupled distributed energy resources (DERs). This research was initiated under the …

This paper presents two photovoltaic (PV) inverter control methods and an analysis of the
two under a significant three-phase transmission line fault contingencies in the Hawaiian …

Momentary cessation refers to an inverter control mode. When the inverter terminal voltage
falls below (or exceeds) a certain level, the inverter ceases to output any current, but …

There has been a consistent rise in grid-connected photovoltaic (PV) systems. Several
studies have reported the impacts of this increase on the distribution networks such as …
