Abstract
This paper presents a power adaptor device, referred
to as smart panel device, allowing the connection of additional
energy sources and storage elements to a domestic photovoltaic
(PV) grid-connected system. The adaptor output port is designed
to behave as a power source/sink, thus enabling its hot-swap
parallel connection to renewable power sources without modifying
their maximum power point (MPP). Moreover, the adaptor device
features a power characteristic with a single controllable MPP and
allows the control of the injected power within the operating range
of the dc–ac grid-connected inverter. The work presents the design
principles of such device by describing the operation of a sliding-
mode controlled quadratic-boost converter. The proper operation
of the device is experimentally verified for several scenarios in
a small PV-based microgrid system including a fuel-cell stack, a
1-kW three-phase wind turbine, a battery charger–discharger, and
commercial grid-connected PV inverters
