Abstract

This article introduces an improved frequency response model that considers the feedback element of under frequency load shedding and analyzes the deficiencies of traditional under frequency load shedding schemes in high proportion of new energy electric power systems, and puts forward a multiple accelerated load shedding optimization method based on frequency changing rate. Simulating in MATLAB/ Simulink shows the validity of the optimization method. Compared with the traditional under frequency load shedding scheme, the optimized scheme has less load shedding, faster and system frequency recovers faster and more stable, which has stronger economical efficiency and adaptability in high proportion of new energy system.

Key words
