Adaptive Hysteresis Current Control for PV Connected Inverter in Digital Grid Router

This paper presents an adaptive hysteresis current control for the Photovoltaic (PV) connected inverter in the Digital Grid Router (DGR), which is composed of multi-functional inverters connected to a common DC bus. The PV connected to the DGR is controlled in both Maximum Power Point Tracking (MPPT) and Specified Power Point Tracking (SPPT) modes, depending on the electricity transactions that the DGR receives from the smart-contracts. The simulation results show that the PV under the proposed control algorithm generates the desired power almost exactly despite the varying irradiance.
