Optimal design and energy management in isolated renewable
A reliable, optimally designed, fully renewable energy based isolated microgrid is required to handle the excess power generated by the renewable energy systems (RES), which is neither stored in the batteries nor fed to the load after reaching the maximum storage capacity of batteries and meeting the load demand.
A study on green hydrogen-based isolated microgrid
In Hendijan, South-west Iran, a hybrid grid-connected system combining energy generation and green hydrogen production was deemed economically viable [3].An isolated microgrid economic analysis in the Canadian Arctic Community of Sanikiluaq revealed a lower cost of electricity generation after integrating a small green hydrogen system to the network [4].

Optimal sizing of islanded microgrid using pelican optimization
The purpose of microgrid optimal sizing is to determine the best combination of component quantity and size to achieve the desired levels of resilience, cost-effectiveness, and dependability [12]. The lack of a main grid in isolated microgrids makes optimal sizing particularly crucial for ensuring a consistent power supply [13, 14]. Numerous
A New Control Strategy for Controlling Isolated Microgrid
Microgrid control in the isolated mode is a highly important subject area. In the present paper, a new method is used for controlling isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, and fuel cell).
