Design and Analysis of a Sustainable LV Residential Microgrid

In the present scenario, power cuts are daily occurrences in many parts of the world. People all over the world would like to avoid these unscheduled power cuts and have a reliable, secure and clean electricity. For an affordable energy usage, sustainable power generation with renewable resources are highly recommended for environment friendly generation of energy with lower carbon footprints. They are isolated from the utility grid in case of any power outage or power blackouts. The key objective of this work is to model a self-sustained microgrid from the existing Indian distribution feeder, which means a small scale interconnected, centralized single controllable system where the particular arena is supplied with distributed energy resources like solar and wind instead of the main grid. The existing system of a particular region supplied with 42 bus system layout connected with 100 KVA transformer. Wind and the solar sources are designed individually and this hybrid energy is interconnected with the layout model to make up a small, modern self-sustained grid called the microgrid. The results are obtained in PSCAD software package with several case studies.
