Implementation of a Proposed Control Mechanism for Energy Management at Load Points Using MATLAB Algorithm (original) (raw)

Energy Management System allows the customers to control, optimize and monitor their energy consumption, which directly translates to a reduction in energy bills. This paper is aimed at addressing such issues, mostly in public places and some other places of interest. The work demonstrates the interaction between the load points referred to as nodes and a central controller, which implements measuring, monitoring, and controlling the energy consumption of various segments of the network, hence conferring on the system operator the powers to regulate the energy consumption of the network from a central point remotely. This work is achieved by measuring and studying the consumption pattern and pegging a threshold, based on a very robust energy allocation plan. The case study is a network of Engineering Students' Hostel University of Agriculture Makurdi, Benue State, Nigeria, which was modelled using a simple MATLAB code to fit the measured consumption curve, which produce the threshold value. These values were programmed microcontroller, representing the central controller, employed to implement the control of energy consumption at the nodes. The results obtained show that the microcontroller was able to control the power consumption by switching ON, when the consumption was below the threshold value and switching OFF, when it was above. The switching action of the microcontroller enabled energy savings, thus translating to reduced electricity bills
