Single-phase rooftop photovoltaic based grid-interactive electricity system

In this paper, rooftop photovoltaic (PV) system is combined with uninterruptible power supply (UPS) system. The optimal design of rating of PV system is for particular house in city of Bhubaneswar, India incorporated. The control schemes with battery energy management are developed for the proposed configuration. The proposed scheme dynamically changes the modes of operation based on load demand and availability of PV power. In addition, the proposed control scheme enables the real power transfer along with reactive power support. The presented schemes are validated through MATLAB/SIMULINK simulation.
