Abstract
Low-voltage distribution area is the “last kilometer” connecting the distribution network and users, and the traditional distribution system is difficult to digitally manage in the low-voltage area, resulting in untimely and imprecise handling of voltage overruns, short-circuit outages, and other abnormal problems.

Low-voltage distribution area is the “last kilometer” connecting the distribution network and users, and the traditional distribution system is difficult to digitally manage in the low-voltage area, resulting in untimely and imprecise handling of voltage overruns, short-circuit outages, and other abnormal problems. With the deployment of smart meters, new sensors, smart gateways, and other devices in distribution areas, digital intelligent monitoring and management based on digital twins in LV distribution areas has gradually become the focus of distribution network research. In view of the profound changes that are taking place in the low-voltage distribution area, this paper first summarizes the characteristics and shortcomings of the existing digital twin research in the low-voltage distribution area, then puts forward the ‘6C’ development goals for the digital transformation of the low-voltage distribution area, introduces the practice work of Guangxi Power Grid Corporation around the ‘6C’ development goals in the low-voltage distribution area. Finally, the future research work of the ‘6C’ development goals for the digital transformation of the low-voltage distribution area is promising. Full article

The article examines the application of controlling in energy and heating (E&H) companies, with particular emphasis on diagnosing the extent to which reporting and management controlling are implemented, as well as identifying barriers that limit the development of their managerial functions. The aim of the study was to determine the extent to which management controlling is applied in the managerial practice of the E&H sector and how its use differs from practices observed in other sectors of the economy. The research employed a mixed methods approach, including a literature review, a case study of controlling implementation in a selected energy company, and a quantitative analysis based on the Managerial Controlling Index (MCI). The central research question addressed the impact of legal, market, and organisational conditions on the scope of controlling in the E&H sector. The findings indicate that E&H companies record lower MCI scores than companies in other industries, regardless of their size, age, or business profile. The article concludes with a set of managerial recommendations outlining directions for the development of management controlling as a tool for supporting decision-making and enhancing integration with the overall management system.
