Abstract
This paper presents the design and implementation
of a low-cost, low-complexity, energy-efficient controller with
remote recharge and load shedding capability. The system is
recharged remotely by an SMS sent to a registered SIM card in a
GSM module, a voltage and current sensor measures the load
power usage, a microcontroller is used to keep track of the power
consumption and signals the relay in order to execute the load
shedding when the predetermined threshold is reached. The whole
system is powered by a power supply unit which converts the 220V
AC from the supply mains to a 5V DC. After the design and upon
testing, the energy measurement circuit worked with minimal
error, the relay switch executed the load shedding function without
delay, the GSM showed good network reception and the operation
of the system was cheap and simple thus satisfying the objective of
the research.
