Design and Integration of AC/DC Hybrid Microgrid by Implementing Maximum Power Point Tracker and Energy Metering System

Abstract

Renewable energy sources are the future energy hub that developing countries are investing in. Due to ever increasing power demand of the world inefficient techniques for power extraction from these resources are not viable. Therefore, efficient methods are being developed. One Such important practical technique is Maximum Power Point Tracker (MPPT) which extracts maximum power available from PV cell or wind turbine regardless of the continuous changing conditions. Moreover, an uninterrupted reliable power supply system is the key for development of any country and satisfaction of its people. To achieve that power system must have the flexibility of drawing out power from more than one supply. In addition, it must provide a backup storage system which takes over in case the main supply is interrupted. This paper introduces such uninterrupted hybrid power system using MPPT technique for the PV cell and wind turbine along with energy metering system to monitor the input and output parameters such as voltage, current, output power and the power factor.
