Modified Lyapunov’s Filter Adaptive Control for Three-Phase Utility Connected System with EV Functionality and PV Integration

This article presents a three phase system equipped with photovoltaic (PV) integration and (Electric Vehicle) EV functionality. EV charging via both AC bus and DC bus are considered. The presented system possesses the capability of operating in utility connected mode as well as islanded mode. In the utility connected mode, the system is controlled through modified lyapunov’s filter adaptive control (MLFAC) technique. MLFAC based current control is capable of extracting the fundamental load component of the nonlinear loads and AC based EV charging load with less oscillations and higher accuracy. The system is capable of supplying reliable power to the loads even during grid outage condition by utilising islanded mode of control and utilising the EV battery. Once, the grid is back online, the system synchronisation back to the grid through developed synchronisation control through the MLFAC-PLL for extracting grid voltage and load voltage angles. The presented work subjects the system to various dynamic conditions and verifies the conformity to IEEE-519 power quality standards and robustness of the system via simulation studies.
