Grid Connected Energy System To Profit From Net Metering And Variable Rate Electricity

Abstract

The rising demand for electricity, coupled with the growing adoption of net metering policies, necessitates efficient energy monitoring and management systems. This paper presents a grid-connected energy storage and monitoring system designed to optimize energy utilization and financial benefits under net metering schemes. The proposed system enables precise measurement, calculation, and display of both consumed and exported energy in a residential environment.The system uses a dual energy meter configuration to measure bidirectional energy flow: one meter tracks electricity supplied to the grid, while the other monitors electricity drawn from the utility. A microcontroller processes data from both meters, calculating net energy consumption and billing for each period. Stable operation is ensured through a regulated power supply and crystal oscillator.By providing real-time monitoring via an LCD display, the system enhances consumer awareness, promotes efficient energy usage, and ensures transparent billing. The proposed approach offers economic advantages to both consumers and utilities while improving system reliability and supporting renewable energy integration.
