Microgrid Integration in Smart Low-Voltage Distribution Systems by Ramanuja Panigrahi, Santanu K. Mishra, Suresh C. Srivastava, and Prasad Enjeti S mart low-voltage distribution system (LVDS) is an essential component in realizing smart electricity grids. In countries like India and other energy-deprived regions of the world, researchers are looking for a holistic approach to integrate millions of small Renewable-powered homes in the LVDS and make the system smart. Restructuring the existing distribution system to form clusters of mi crogrids is an important step in achieving a smart LVDS. The realization of mi - crogrids in LVDS can take different shapes in different countries depending on the structure of the distribution grid. This article envisions a possible Digital Object Identifier 10.1109/MPEL.2022.3169318 Date of current version: 16 June 2022 2329-9207/22©2022IEEE approach to implement microgrids in a smart LVDS with radial distribution. The article proposes that radial LVDS following a distribution transformer can be converted into a three-phase ac microgrid. Thus, segregating the existing LVDS into a smart LVDS with as many microgrids as the number of distribution transformers. However, this approach leads to many issues so far as microgrid operation is concerned. To address these issues, this article envisions replacing the low-voltage distribution transformers with solid-state transformers (SSTs). It will enable the LVDS to control the power exchange between the phases within a microgrid as well as power exchange between different microgrids. This approach will also support smart homes and their interactions within a microgrid. Various existing microgrid related grid codes are also reviewed to complete the discussion.
