Improving Power Distribution in Standalone Microgrids: Case Report: Using VBD Control

A microgrid is a small low-voltage power supply network designed to power a sensitive local load set. The microgrid includes distributed generation systems, distributed energy storage devices, and loads. In many of them, the power required by the system is provided by renewable sources that are uncertain and variable in nature, which makes it more difficult to control these systems than conventional power systems. Fluctuations in generated power may cause some problems in normal control performance. Proper operation of a microgrid is only possible if there is a proper control system, and modern power systems need to increase information and flexibility in control and optimization to ensure the ability to maintain production balance and load under severe disturbances. The microgrid has two operating modes; Network-connected mode and island mode the most important challenge in using microgrids in island mode is to control it. Due to the small amount of load and the large volume of power sources with variable production such as wind turbines and solar panels, island microgrids need more flexible tools such as storage.
