Integrating Scheduling System for Managing A Huge Number of Electrical Devices

Abstract

National power plant company (PLN) has responsible to maintain the increasing electricity in Indonesia. Thus, various efforts have been implemented, but it still causes power outage. In the educational sector, this problem disrupted the teaching and learning processes, so that Diesel Generator (DG) is applied as the source of electricity backup. However, The capacity of DG is less than that of PLN. So, this paper proposes integrated scheduling system to manage DG capacity. This system is intended to be able to control the power usage in a building. Here, a prototype consists of three main parts, namely: (1) the control device section, (2) the central controller device section, and (3) the user interface section. The control device section consists of a ZMCT103C current sensor, an ESP32 microcontroller and a relay. Part of the central controller device is Raspberry Pi 3, which is installed as web server to serve HTTP requests from control devices to interface with users. The user interface section is a dynamic web display to facilitate monitoring and controlling by centralize system. The integration test results of classroom scheduling system is able to run well with 0% error rate. The classroom scheduling system is able to optimize power usage by 11,9% or save 2771 Watt from the overall electrical power in the building.
