Development of a Priority-based Load Management System to Address Variability in RE Power Injection in National Grid

Abstract

Variable renewable energy injection into the grid makes the smooth operation of the grid challenging. Demand response enabled smart grid addresses the challenges by managing demand. This work developed a priority based load control system that controls the demand by switching the loads according to the priority depending on grid parameters like voltage and frequency. A laboratory setup has been developed along with a smart meter that can measure the grid voltage and frequency. By measuring the grid voltage and frequency, the device can switch off or on the connected priority loads.
