“…However, the recent interest of some of the funding agencies in DC systems elevated a portion of these studies toward hardware experimentation. A DC testing grid is presented by Albu et al in [158], the established grid is a laboratory scale microgrid to examine the operation of low-voltage (230 V) DC grids. Extended details about the system construction, hardware implementation and the developed LabVIEW monitoring application are provided.…”

“…The study focused basically on the evaluation of PQ indices in time domain and do not consider specific time windows for performing the analysis. This paper expands the work of [4] and [5] while reevaluating former definitions and metrics proposed to quantify some of the PQ indicators in time domain. The challenge was to define metrics that avoid unquantifiable formulas for the perfect (desired) DC signal against which we will compare several real signals.…”

“…In [4] an experimental remote controlled monitoring system for a laboratory scale DC microgrid operating at 230 V was developed to extract voltage and current operation characteristics of several DC native loads and to calculate a range of power quality indicators. The study focused basically on the evaluation of PQ indices in time domain and do not consider specific time windows for performing the analysis.…”

“…This range of losses in a DC microgrid can be lowered to 10% to 15% by using a higher efficiency conversion for multiple loads. This topology outperforms the currently existing topologies due to the superior economics of bulk conversion versus converter at every point-of-use [17]- [25].…”
