Micro-grid is a small low voltage power supply network designed to power a local sensitive load set including distributed generation systems, distributed energy storage devices, and loads. Mostly, the required power by the system is provided by renewable resources that are unsafe and changeable yielding difficulties to control these systems in comparison with conventional power systems. Fluctuations in the generated power may cause some problems with normal control performance, in which proper performance of a micro-grid is possible only if there is a proper control system. Moreover, modern power systems need to increase information and flexibility in control and optimization to ensure the balance of production and load under severe disruption. In this paper, the performance of voltage and frequency control of the islanded micro-grid is investigated using the developed VBD control and its purpose is to increase the flexibility in the applications of energy storage devices. The micro-grid and power generation resources and VBD control method and its control over the storage devices are discussed in details. Performed simulation in MATLAB software includes a transient and dynamic micro-grid response with a comparison of the presence of storage devices on the voltage and frequency control of the micro-grid.
