An Effective Dump Load for Three-Phase Autonomous Micro-Grids

Abstract

This paper presents a simple and reliable solution for frequency regulation in an autonomous Hybrid Power System (HPS). The study deals with rated powers of tens of kilowatts, where the most usual frequency regulation methods are those based on electronic power control, without any mechanical regulation on the generator's part. The paper focuses on an optimized three-phase dump load with low current harmonics injection. For the proposed configurations, simulations were performed by using the MATLAB/Simulink environment.
