The best and most advanced type of end-user payment and energy management plan device for electricity is a smart electricity prepaid meter. The main issue that power distribution service providers want to address is non-technical losses due to inefficiencies associated with the metering system. Unlike the traditional estimated billing methodology, this technique makes electricity use easily accountable and equitable to both consumers and power service providers. To lessen the frequency of electricity meter tampering, this study aims to develop a smarter prepaid meter. To the power distribution service providers, low revenue collection due to non-technical losses, especially tampering with electricity meters, is the main obstacle. By gaining illegal access to prepaid meters, electricity thieves can alter the proper power flow between the customer and the service provider and evade paying for electricity. The proportional integral derivative (PID) controller and a voltage sensor are the tools used to address this issue. When comparing the PID controller in closed and open loops, the products or results from each evaluation indicate that the closed-loop got 0.5 error rate while the open-loop got 0.85 error rate. Analogue meter efficiency was 65%, while smart meter system without PID got 86% efficiency. 93% efficiency being the highest was recorded with the use of smart meter system with PID. The research policy employed the strict evaluation of the sensor, the proportional integral derivative controller associated with the prepaid meter and the meter tamper response for improved distribution efficiency.
