Abstract
This study aims to solve the problem of uneven electricity use in homes that share a three-phase power supply. This unevenness happens when too many houses rely heavily on just one or two of the three power lines, leading to wasted power, overloaded lines, voltage drops and even blackouts. The growing use of solar panels on homes makes this problem even worse since the amount of electricity they produce can fluctuate .
To fix this, the project created a smart system that uses a microcontroller and WiFi technology to constantly monitor and adjust how electricity is distributed among the three power lines. It keeps track of how much power each house uses and how much solar energy is being produced, then automatically shifts houses between the lines to keep things balanced.
Tests of this system show losses reduced from 138 kW to 9 kW—resulting in cost savings of $193.2, or $3.75 per house. The system achieved a simple payback period of less than one month. Furthermore, the lowest network voltage improved from 206 V under unbalanced conditions to 221 V after implementing the balancing solution.
This study is important because it shows how to better manage modern power grids that include a lot of solar energy. By using this system, power companies can ensure a more stable and dependable electricity supply to homes while also supporting the use of renewable energy sources like solar power.
