At present, there have been many studies on the optimization design of grid-connected and off-grid RES-H2 production systems. Grid-connected H2 production system [ 5, 6 ] uses surplus electricity to produce hydrogen, further achieve the goal of RES consumption, and fails to achieve the goal of "zero carbon hydrogen production".
However, one possibility to establish a smart grid in South Africa is the use of off-grid microgrids. As a sub-category of a microgrid —i.e., an independent, regional, or municipal energy system (Longe et al., 2017 )—an off-grid microgrid operates completely independently from the national grid.
The off-grid microgrids have no physical connection to the main grid, sometimes due to the lack of a nearby or economically viable transmission and distribution infrastructure.

RePower, formally known as "Improving Renewables Penetration Through Plug and Play Microgrids," aims to enhance the penetration of renewable energy in rural communities in Madagascar, Niger,
The U.S. Department of Energy defines a microgrid as a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. 1 Microgrids can work in conjunction with more traditional large-scale power grids, known as macrogrids, which are anchored by major
1. Introduction The MicroGrid (MG) concept [1], intended as a cluster of local consumers and generators, represents an efficient way to integrate distributed Renewable Energy Sources (RES) with controllable generators and Energy Storage Systems (ESS), that can operate both in grid-connected and islanded mode [2]..

Off-grid is a self-sustaining electricity ecosystem in which the premises are disconnected from the grid. Electricity must therefore be self-generated for consumption, and usually storage. Microgrid, on the other hand, is a local collection of electricity sources and
To offer a dependable and resilient power supply, particularly in distant or off-grid locations, a solar microgrid is a decentralized energy system that combines solar power generation with energy storage and cutting-edge control technologies.

Distributed energy generation further enhances grid
Off-grid systems. Solar panels: For off-grid applications, the key to solar panels is durability and efficiency. Since off-grid applications are often deployed in remote areas, solar panels must be able to withstand harsh environmental conditions. Energy storage: Similar to microgrids, battery storage is critical in off-grid systems.

The off-grid microgrids have no physical connection to the main grid, sometimes due to the lack of a nearby or economically viable transmission and distribution infrastructure. Since there they are isolated from the main network, the remote microgrids operate in the island mode throughout their service life.
A microgrid is a small portion of a power distribution system with distributed generators along with energy storage devices and controllable loads which can give rise to a self-sufficient energy system. From the utility grid side, a microgrid is seen as an equivalent generator that is able to seamlessly disconnect and operate autonomously
Unlike off-grid microgrids, which are designed to operate in island mode, on-grid microgrids are integrated with the grid and can be used to supplement or replace power from the grid. In some cases, they may also be used to generate excess power that can be sold back to the grid, providing a source of revenue for the microgrid owners.
Microgrid. A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A '' stand-alone microgrid '' or '' isolated microgrid '' only operates off-the-grid and cannot be connected to a wider electric power system. [4]
