Component Model of AC Microgrid for Short-Circuit Analysis

Microgrids are self-sustaining systems that are small in size. They have become more popular in recent years, especially with the addition of renewable energy sources. Due to the degree of unpredictability this penetration of the renewables brings to the characteristics of microgrid. A thorough understanding of short-circuit issues in these systems is essential. In this study, different components of an AC microgrid (MG) are modelled, and a thorough explanation of short-circuit analysis (SCA) methodologies is included. SCA entails a systematic research of electrical installations to comprehend the characteristics and ramifications of short circuit problems. Micro grid's reactivity is improved and optimised with the aid of short circuit modelling and assessment, which eventually increases the microgrid's capacity to withstand and recover from disruptions. It supports in the development of effective protection measures and the reduction of potential equipment damage by modelling fault scenarios and analysing the implications that occur in microgrid systems. This research also presents the various short-circuit analysis methodologies of MG in tabular format. Modelling of different components of MG including electric vehicle (EV) as load has also been discussed in this paper.
