Abstract
Geomagnetic induced current (GIC) caused by geomagnetic disturbance (GMD) can be a serious threat to a stable electrical power grid operation. GIC that is induced in the earth magnetic field flows through the neutrals of grounded-wye transformers may lead to increasing reactive power consumption which can result to voltage collapse. Therefore, it is important to study the evaluation of this event on the electrical power grid. This paper presents the analysis of GIC modelling and calculation in a 4 bus test case system using Power World Simulator. The value of calculated GIC using Power World are validated and compared with theoretical using nodal analysis method. Based on the study conducted, it is found that the geomagnetic storm magnitude and direction in degrees can affect the GIC values. � 2020 IEEE.
