Distributed Finite-Time Fault-Tolerant Control of Isolated AC Microgrids Considering Input Constraints

This paper presents a distributed fault-tolerant finite-time control scheme for the secondary voltage and frequency restoration of islanded inverter-based Alternating Current (AC) Microgrids (MGs) considering input saturation faults. Most existing methods commonly design layer based on ideal conditions channels MG without any faults disturbances. At same time, MGs are exposed to actuator that can significantly impact MGs, lead in unstable situations. One other typical practical constraints multi-agent systems such as is saturation. The novel idea consensus-based synchronizes MG’s their nominal values all DGs within finite irrespective multiple faults, including partial loss effectiveness stuck simultaneously. Finally, performance proposed schemes verified by performing an offline digital time-domain simulation test system through couple scenarios MATLAB/Simulink environment. accuracy AC compared previous studies, illustrating privilege that.
