Extremum Seeking control of smart inverters for VAR compensation [PDF]

2015 IEEE Power & Energy Society General Meeting, 2015
Reactive power compensation is used by utilities to ensure customer voltages are within pre-defined tolerances and reduce system resistive losses. While much attention has been paid to model-based control algorithms for reactive power support and Volt Var Optimization (VVO), these strategies typically require relatively large communications ...

Low-Cost Communication Interface between a Smart Meter and a Smart Inverter

Energies, 2023
The need for a low-cost interface between the grid and small (<250 kW) renewable distributed energy resources (DERs) is growing in importance as the number of small DERs continues to grow. In this study, a system architecture was proposed to investigate paths to an affordable interconnection for small renewable DERs.Then, a low-cost communication ...
