A Benchmarking Testbed for Low-Voltage Active Distribution Network Studies

Abstract

The evolution of distribution networks to active systems as a consequence of the increased penetration of distributed energy resources and the electrification of traditionally fuel-based activities have changed drastically the landscape of power systems operation promoting the necessity of benchmarking tools for planning studies. Nevertheless, there is a scarcity of such tools that enable the holistic analysis of modern power systems according to the new grid standards. In this paper, a multi-purpose benchmarking testbed for low-voltage active distribution networks is introduced. The testbed comprises a granular residential appliancelevel dataset, a benchmarking framework based on quasi-static simulations, a set of technical indices and a non-intrusive load monitoring tool. A suite of benchmark case studies including overvoltage, undervoltage and line congestion is presented, supported by ancillary trouble-shooting services, such as voltage control and demand response. The proposed testbed can be a useful tool for distribution system operators to evaluate the operating conditions of the grid without violating technical limitations, test new technologies, identify operational challenges, and foresee grid investments.

Digitalization Processes in Distribution Grids: A Comprehensive Review of Strategies and Challenges

“…The integration of digital technologies, especially smart meters, is reshaping metering, billing, and customer service in distribution power systems, marking a shift towards more efficient, reliable, and customer-oriented operations. Study [82] underlines the intricate analysis enabled by smart meter data, from load forecasting to detecting non-technical losses (NTLs), emphasizing the role of smart meters in enhancing power network operations.
