Power hardware-in-the-loop testbeds for advances laboratory testing of smart grid applications

Abstract

This paper assesses practical aspects related to advanced laboratory testing of smart grid applications with Power-Hardware-in-the-Loop (PHIL) approach. Particularly, the general features together with a set of extended use-cases for PHIL testing are introduced. An existing laboratory at TU Dortmund University is presented and considered as a reference for describing the architecture and the principal components of typical advanced laboratory testing infrastructures based on PHIL approach. A number of exemplary testbeds are provided to show the potentially applications of advanced PHIL testing for low-voltage distribution grids.

Optimal coordination of electric vehicle charging and photovoltaic power curtailment in unbalanced low voltage networks: An experimental case

“…A supervisory control and data acquisition interface controls both power amplifiers. In this setup, the PV power at the DC side of the inverter is provided by one of the power amplifiers (configured in DC bipolar current mode) by a single cell PV model developed in RT‐Lab [25]. The PV inverter is connected along with a variable resistive load to the busbar 2 (the cabinet in the middle).…”
