“…The standardization of DC electricity meter testing does not fully address immunity to DC-specific disturbances. In this context, an arbitrary waveform testbed was created in [83] for testing DC electricity meters. This testbed can assess meters in the presence of broadband disturbance signals with frequency components up to 150 kHz.…”

This manuscript presents a comprehensive review of recent advancements in electrical distribution networks, with a specific focus on the incorporation of direct current (DC) applications. The research aims to comprehensively address the current and future aspects of DC, spanning from the distribution level to the utilization level. The renewed interest in DC power systems has led to the investigation of several transitional challenges in recent years. A significant portion of these efforts has been dedicated to determining the feasibility of applying DC to specific use cases. Additionally, the literature has explored design considerations such as system architecture and voltage levels, the integration of DC into existing distribution networks, load flow (LF) computations, and the distinct safety concerns associated with DC power systems. In this paper, the various research endeavors are categorized, evaluated, and scrutinized to assess the current state of the transition from a purely alternating current (AC) distribution system to a solely DC or hybrid AC/DC distribution system. A bibliometric analysis is conducted, constructing a network of co-occurrence based on author-provided keywords, which reveals the primary research foci in this domain. The barriers hindering the widespread adoption of DC distribution systems and potential solutions are also discussed. Moreover, this article synthesizes ongoing efforts to address these obstacles and delineates future research directions by emphasizing the existing knowledge gaps.

“…The need for measurements to underpin new definitions of DC PQ is addressed in the European metrology project "20NRM03 DC Grids" [14] by measuring and analyzing the distortions occurring in LV DC microgrids and developing reference systems for the calibration of DC power meters [15] and DC PQ analyzers, and for testing DC equipment such as DC electricity meters in the presence of well-defined distortions [16]. The first measurement campaigns have been executed already in LV DC microgrids in Malaga Smart City in Spain, with micro wind turbines and PV panels at a voltage level of 48 V [17], the Green Village in Delft, the Netherlands, with LED streetlights and PV panels and operated at 350 V [18], and three different public EV charging stations in Germany [19].…”

The growing use of renewable energy sources and sustainable technologies has increased the attractiveness of low-voltage DC distribution grids. Despite initial research and standardization work, the definition of power quality (PQ) issues and their related compatibility levels in DC grids and the related measurement techniques remain in their infancy. The lack of available measurement results obtained in real-world situations is a major shortcoming. In this paper, the results of a measurement campaign obtained in a configurable bipolar 350 V/700 V DC microgrid in an urban environment are presented. Voltage and current signals were registered continuously at different positions in the microgrid with a sampling rate of 500 kSa/s while changing the configuration of the microgrid; the resulting data were analyzed afterwards, with a focus on DC voltage and current variation, ripple, and spectral analysis. The measurements were taken with custom-designed metrology-sound measurement equipment. The measurement results provide input to the development of DC PQ analysis tools and the standardization of DC PQ measurement methods. Furthermore, the experience obtained will be beneficial for utility companies and regulatory authorities for reliable planning-level and compatibility-level surveys.
