Projects:2019s1-182 Power System Inertia Modelling in a Renewable Energy and Battery Storage Based Microgrid

Abstract

Introduction

Case 1: Brazil and Paraguay November 2009 When the Itapiu hydroelectric dam on the Paraguay-Brazil border suddenly stopped producing 17,000 megawatts of power, outages quickly spread through both countries. The key reason of the blackout is that the disturbance was triggered by the automatic disconnection of 765 kV transmission line whose inertia is less. Case 2: South Australia September 2016 In 2016, South Australia was hit with a strong storm that caused serious damage to the electricity transmission infrastructure leaving 1.7 million people without power. The key reason of the huge blackout is that there was significantly lower inertia in SA in the most recent event, due to a lower number of on-line synchronous generators. This resulted in a substantially faster Rate of the change of frequency (RoCoF) compared to the other events, exceeding the ability of the under-frequency load shedding schemes (UFLS) to arrest the frequency fall before it dropped below 47 Hz.
