“…IEC TS 62578:2015 [11] discusses the emission values below 150 kHz, but it does not define the limits for the emission. EMI issues in the previous installation [2] are discussed in two previous publications [12], [13].…”

“…The DC network is implemented as an IT system and there are no end-user equipment directly connected to the DC network. Hence, the disturbances in the DC network have no effect on electrical or equipment safety, but they could generate radiating interferences and hinder the use of power line communication (PLC) [12], [13]. EMI issues could arise especially in aerial networks, that are normally constructed by using aerial bundled cables (AC) manufactured and installed according to HD 626-5D S1 [14].…”

When a low-voltage DC distribution system installation is realised in a public power distribution network, an extensive specification is required to ensure electrical and equipment safety and compatibility between the existing grids and customer-end installations. The goal of the paper is to give to a reader an understanding what is required for safe and reliable operation of the LVDC distribution in an actual distribution environment. The paper discusses the mechanical and electro-technical aspects of the pilot installation. The focus is on the common system and power electronics specifications.

Flexible DC distribution system has become the research and development trend of the future distribution network with its unique advantages such as high efficiency and flexibility. However, the DC fault identification and protection is challenging due to the fact that the short-circuit current provided by converters is limited and last for a very short period, how to identify and isolate faults reliably using limited fault transient information becomes a serious problem faced by system protection. Based on the analysis of the fault characteristics of three typical faults in the DC distribution system, the setting principle and the calculation methods are proposed, and the reasonable range of protection setting boundaries is derived. According to the requirements of protections, the parameters of the actual DC distribution system are used for setting calculations, and a complete set of DC line protection schemes is designed in this study. Finally, the performance of the proposed protection scheme is verified in PSCAD/EMTDC simulation platform, the built simulation model has been successfully applied to the analysis and calculation in the commissioning of the DC distribution system.

“…As the urban electricity load continuously grows, the power quality requirements of some loads become increasingly stringent, and the permeability of new energy and electric vehicles is gradually increasing, the flexible DC distribution network has become an important direction for the upgrading and rebuilding of the urban distribution network [1, 2]. Many countries and regions have focused on the research of the flexible DC distribution network in recent years, mainly the power sharing optimisation [3], the voltage stabilisation [4], the safety of DC network [5], and the application of new energy in DC network [6].…”
