Energy Supply of Sensitive Areas as an Inverter-Based Microgrid During Stiff Power System Black Out

Authors

Abstract

Multi supply in sensitive areas - as an inverter based Microgrid - is necessary for improving reliability and stabilizing the network in case of losing one or some of the electricity generation units. In addition, islanded mode of Microgrids is a guarantee of continuing operation during black out or failing stiff power system. In order to utilize variety types of distributed generations and renewable energies in Microgrid structure, usage of Power Electronic Interfaces (PEI) is inevitable. As a result, Frequency Tracking (FT) method with decentralized control in order to stabilizing inverter-based Microgrid is introduced. In the proposed novel method, all generation units follow the frequency of one generation unit as a Master and provide required power in network after deployment of Droop Control. The simulation results of proposed control system on two distinct networks in PSCAD confirm its proper functioning.
