Self-sustainable autonomous microgrids with 100% converter-connected generation are most suitable for powering remote areas without impacting the environment. This work focuses on the regulation aspect of such islanded microgrids by sizing and controlling energy storage systems to support the renewable energy-based microgrids. Each generation unit in the microgrid acts as a voltage-source that contributes to frequency and voltage regulation, wherein the regulation is achieved by a modified droop control that emulates the inertia property of synchronous machines. The size of energy storage systems that support this task is estimated based on the allowable regulation standard and control scheme. The designed storage and control are validated with the help of real-time simulation.
