| Summary: | This thesis proposes a realization of the photovoltaic(PV) panel to PV panel (P2P) method for the modular differential power processing (mDPP). The approach is modular and permits panels to be added to or removed from either series strings or paralleled connections. A voltage inner loop and power outer loop control strategy tracks the individual maximum power point of the PV panel, while the power converters only process the differential power. The proposed method decouples
the control loop performance of each PV module, making design simple. Simulation and experimental results validate the Plug-and-Play function for scalable PV system and MPPT accuracy. Hardware prototype is also built, and both indoor and outdoor experiments are provided to exhibit the advantage of this P2P method. |
