A microgrid system is a group of interconnected distributed generation, loads, and energy storage operating as a single controllable entity. Many published articles recently focused on distributed generation, system control, system stability, power quality, architectures, and broader focus areas. This work analyzes microgrid: alternating current (AC), direct current (DC), and hybrid AC/DC microgrid systems with bibliometric network analysis through descriptive analysis, authors analysis, sources analysis, words analysis, and evolutionary path based on the Scopus database between 2010 and 2021. The finding helps find out the top authors and most impact sources, most relevant and frequently used in the research title, abstract, and keyword, graphically mapping the research evolved and identifying trend topic.

INTRODUCTION A microgrid system comprises interconnected loads and the distributed generation that perform as a single controllable system concerning the grid [1]. One or more types of distributed power energy (solar panels, wind turbines, micro-hydro, diesel engine, or other generation), load, and energy storage (usually batteries) are contained within a microgrid system. A microgrid system may connect or disconnect from the distribution grid, permitting it to function in the grid-connected or island-mode operation [2]. Furthermore, whether there is a blackout or a problem on the primary grid, the microgrid system can detach from the grid and serve its local demands in islanded mode [3]. The microgrid system is an alternative to the conventional electrical power system to supply demand. Microgrid systems also can be applied in streets, residential, neighborhoods, campuses, hospitals, communities, localities (towns and villages), small islands, organizations, military, and business centers [4]–[8]. A microgrid generally comprises three major components: distributed generators, loads, and storage elements. It can run independently or connect to the main network, either low- or medium- voltage [9]. Electricity supply for islands and isolated places is developed by exploiting local energy potentials, especially renewable energy sources (RES) [10]. Due to their flexibility, quick operation, and low complexity, most islanded microgrid power systems rely on diesel generators for their electrical source. However, diesel generators have significant running expenses [11]. The hybrid device setup for a typical microgrid system is shown in Figure 1. The direct current (DC) bus connects the DC supply, battery energy storage, and the load to the inverter. The load can be an alternating current (AC) or DC load located close to the power source or distant (external load) from the microgrid system. The charging regulator is connected to the battery using a two-way DC to DC converter. The DC to DC
