Historically, centrally computed algorithms have been the primary means of power system
optimization and control. With increasing penetrations of distributed energy resources …

Electric distribution grid operations typically rely on both centralized optimization and local
non-optimal control techniques. As an alternative, distribution system operational practices …

High penetration of distributed energy resources presents several challenges and
opportunities for voltage regulation in power distribution systems. A local reactive power …

In this paper, we consider the manifold that describes all feasible power flows in a power
system as an implicit algebraic relation between nodal voltages (in polar coordinates) and …

We consider the problem of voltage stability and reactive power balancing in islanded small-
scale electrical networks outfitted with DC/AC inverters (“microgrids”). A droop-like voltage …

In this paper, we propose a distributed voltage control in power distribution networks through
reactive power compensation. The proposed control can operate in a distributed fashion …

The new IEEE 1547-2018 standard includes dynamic Volt/VAr control for photovoltaic (PV)
smart inverters. While recent research has addressed the problem of optimal inverter …

Voltage regulation in distribution networks is increasingly challenged by the penetration of
distributed energy resources (DERs). This paper develops a distributed voltage control …

The revised IEEE 1547 Standard together with the grid codes from several European
countries require the contribution of photovoltaic inverters to the reactive power and voltage …

Time-varying renewable energy generation can result in serious under-/over-voltage
conditions in future distribution grids. Augmenting conventional utility-owned voltage …
