Power quality conditioner and load management system for an integrated residential grid

This paper presents the process of design, development and testing of a power quality conditioner and a load management system to be integrated as a part of a small grid (Nano 3kW) system suitable for residential power needs. This set-up is being developed at the college laboratory so as to facilitate execution of various studies in the domain of integration of renewables in small distribution systems. The grid is powered by solar and wind energy sources which are synchronized. The power quality conditioner is designed to take care of power quality issues that arise due to the integration of renewable energy sources and operation of power electronic loads. A load management system capable of identifying, monitoring and controlling the loads connected to the system is also put in place using Near Field Communication(NFC) and IPv6 over Low Power Wireless Personal Area Network(6LoWPAN) technologies. The working of the power quality conditioner as well as the load management system are implemented and tested in hardware as individual stages before they become part of the grid and agreement is observed between the simulation and experimental results.
