  1. 1. Design of a Future Residential Hybrid Microgrid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ahmad Talaat Hifzy; Wilhelm Westermark; [2021]
    Keywords : Energy management; grid control; grid operation; hybrid microgrid; PV system; MPPT; BESS; DER; BIC;

    Abstract : As we are moving towards a future carbon-neutralsociety, development of residential microgrids attracts much attentionaround the world with its efficient utilization of renewableenergy. A residential microgrid is a small power system fora house, which consists of a solar photovoltaic (PV) source,a battery storage, residential loads, and an interface to thegrid. READ MORE

  3. 2. An FPGA Based MPPT and Monitoring System : suitable for a photovoltaic based microgrid

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Rongpeng Zheng; [2019]
    Keywords : Microgrids; Monitoring System; Maximum Power Point Tracking MPPT ; Stand-alone Mode; Grid-connected Mode; FPGA; Verilog HDL.;

    Abstract : Microgrids containing photovoltaic (PV) cells and wind power gain more and more interest. These microgrids may work in stand-alone mode ("islanding") or be conncted to the main grid. In both modes of operation, power quality must be monitored and controlled. This report focuses on microgrids and aims to implement a monitoring system based on FPGA. READ MORE
