A study of SCADA Designer application for developing demand side management program

Abstract

Demand side management (DSM) is one of the main challenges of general power systems and smart grids. It plays a vital role in supporting customers and utilities to use electricity efficiently and economically through techniques that redistribute peak, off-peak and normal load demand. This paper has studied the application of SCADA Designer software to design a DSM controlling and monitoring program for an electrical system in our laboratory. The experimental system includes hardware devices such as a three-phase asynchronous motor with a squirrel cage rotor, a servo motor, a resistive load, a measurement meter and other auxiliary devices that are connected to simulate a mixed load of electricity customers. The paper has developed an algorithm flowchart for designing the software program using SCADA Designer. Additionally, the load profile is controlled by the servo motor to establish various DSM operation scenarios. These scenarios based on the experimental system have verified the working efficiency of the DSM technique in this paper, and it also contributes for reducing the peak load of the power system.
