In this paper, a Luenberger observer-based microgrid control strategy is proposed to enhance the power quality of microgrids, when grid loads are mixed and strongly non-linear. To improve performance under condition, observer designed for three phase grids. On basis observer, components different frequencies sequences voltages currents obtained accurately. The virtual impedance designed, which ...

The penetration of distributed generators (DGs)-based power electronic devices leads to low inertia and damping properties the modern grid. As a result, system becomes more susceptible disruption instability, particularly when demand changes during critical loads or needs switch from standalone grid-connected operation mode vice versa. Developing robust controller deal with these transient case...

This paper investigates an observer-based secure control problem for platooning of connected vehicles in the presence Denial-of-Service (DoS) attacks. DoS attacks usually prevent vehicle-to-vehicle data packets transmission which will lead to performance degradation system or vehicle collision. To deal with attacks, we consider mechanism estimate state based on available sensor measurements sig...
