Micro-grid Transient Response Improvement

"In this paper, an islanded micro-grid that is feeding variety type of loads is considered. Micro-grid contains an inverter based fuel cell unit and gas power plant equipped with synchronous generator. A power management control loop is integrated to the fuel cell inverter controller in order to enhance the stabilization of system frequency and voltage during transient conditions such as load variations and short circuits. The feasibility of the proposed control strategy is demonstrated trough several simulated case studies in PSCAD environment."
