For distributed inverter voltage tracking, phase-locked loop are conventionally utilized to achieve synchronization. Its implementation requires a separate Phase-Locked Loop (PLL) with the necessary hardware, and there is still a constant offset in the reference tracking. In previous work, authors proposed a controller “matrix” based on Internal Model Principle to achieve synchronization control for...
In order to ensure synchronized operation of inverters used in renewable energy systems, the output voltage magnitude, frequency and phase angle must be consistent with that of the power grid when it is in islanding operation. Based on author's previous work on single-phase inverter synchronization control with internal model principle, this paper extends the application of that principle to achieving...
The recently developed power electronic devices allow the flexibility of power and/or reactive power generation or consumption via electric vehicle charging. It is envisioned that a fleet of electric vehicles may provide auxiliary means for frequency and voltage regulation to improve the power quality and the stability of the power grid. This emerging technology is especially important for microgrid...
