Smart approach for Under Frequency Load Shedding Strategy based on Frequency Linked Pricing

Abstract

This paper presents a new approach of under frequency load shedding scheme based on frequency linked pricing. Idea is to find sensitive node of system where there are chances of more fluctuations of frequency and more chances of voltage instability. Under frequency and low voltage nodes are more sensitive than other nodes in the system. ABT meter is installed having special design and load is shed as per priority. Algorithm is validated using real time data of actual feeder for 24hrs frequency fluctuations.
