Department of Mechanical Engineering, Mechatronics and Robotics Section, Faculty of Engineering, The British University in Egypt, El Sherouk, Cairo 11837, Egypt Department of Electrical Power Engineering, Faculty of Engineering, Cairo University, Cairo 12613, Egypt Department of Electrical. . To address this critical issue, this research proposes an application of virtual inertia control as a means to enhance the frequency stability of interconnected power systems characterized by a high penetration level of RESs. The proposed approach leverages a derivative control technique to enable. . Even with adequate frequency control reserves, isolated microgrids' frequency can experience significant excursions and easily deviate from nominal operating conditions due to the low system inertia and quick changes in the output power of wind and solar power sources. As a result, it is difficult. . Islanded microgrids (MGs), characterized by distributed generators, power consumers, and energy storage systems (ESSs), are designed to signi cantly enhance self-sustainability of future distribution networks and to provide energy for remote communities. In order to have a stable system, both. .
