Photovoltaic (PV) energy is one of the biggest players of renewable energy installations although soft costs remain as the major barrier for higher penetration of PV systems. To address the cost challenges, a plug-and-play (PnP) system for a quick, low-cost installation is proposed and designed. The method is much less invasive and labor intensive than the traditional installation methods. This paper presents the PnP electrical system, with emphasis on the controls, software, and system-level communications within the system. A PV utility interface circuit has been developed for automated electrical safety checks and authentication for the PnP PV system. A data protocol has been used to deal with the master–slave controller setup in the system. This research has the potential to reduce the residential PV system price by $0.6/W.}, number={2}, journal={IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS}, author={Khan, Md Tanvir Arafat and Norris, Gregory and Chattopadhyay, Ritwik and Husain, Iqbal and Bhattacharya, Subhashish}, year={2017}, pages={1337–1346} }

The system allows for high penetration of renewable generation with energy storage at the distribution level. FREEDM system consists of an energy router, which is the power electronics based solid-state transformer (SST) that interfaces distributed generation, storage and local loads on the low voltage side with the medium voltage node of the distribution grid. In this paper, state-space modeling and dynamic performance of the SST is analyzed along with the renewable generation sources and storage components with the goal of studying the feasible operating points of the FREEDM system. The actual model of the single-SST system amounts to highly complex dynamics with more than hundred state variables. Singular perturbation based model reduction techniques are applied, thereby leading to a 70th order state-space average model suitable for AC and DC energy cell system sizing, stability analysis, and controller design. The analysis with the system model revealed the SST input stage system parameters have the dominant effect on the feasible operation region.}, booktitle={2016 ieee energy conversion congress and exposition (ecce)}, author={Khan, M.
