Abstract
This work proposes an intelligent control method for ensuring the Direct Current (DC) link voltage stability and for improving the DC-link voltage transient response in a residential Energy Router (ER). This ER is an interface among the main grid, local AC or DC loads and sources. When connecting different loads to the DC-link, the classic Proportional Integrator Derivative (PID) controller has been unable to provide a stable DC-link voltage. In this study, the PID controller will be compared with the proposed fuzzy logic controller in different DC load levels. The results prove the enhanced functionality of the proposed control method.
