Microgrid Control to Ensure Stability and Increase Flexibility in Storage Applications

The purpose of this paper is to use energy storage resources in the microgrid to control its voltage and frequency. Today, due to the manifestation of the benefits of microgrids, the use of renewable sources and energy storage has increased, and therefore these systems must be able to control microgrids. The VBD method is proposed to coordinate these forces with energy storage to help regulate the voltage and frequency of the microgrid when necessary and to supply more power to the microgrid repeatedly. Therefore, new energy sources such as photovoltaics, wind turbines, or fuel cells are a real reason for generating electricity in these areas, and despite the initial cost of installing such new power generation equipment, the above reasons have made the use of these resources a wise reason in remote areas. Because the imbalance of power generation and consumption causes deviation and change of network frequency and may cause serious damage to frequency sensitive loads, so one of the important issues in microgrids separate from the network is power and frequency control.
