DG Placement Based on Short Circuit Fault Current Component Analysis

Producers of electrical energy are always required to meet the power needs of consumers. The addition of Distributed Generation (DG) is one of the most frequently used methods to maintain a balance between electrical power and load. Generally, load flow analysis is most often used to determine the placement of DG. If choose the wrong DG placement, it can increase the risk of adding a short circuit fault current level. This paper aims to determine the placement of DG using short-circuit fault current component analysis. The DG used in this paper is a Double Fed Induction generator (DFIG) wind power plant. This type of wind power plant is the most frequently used compared to other types. The short-circuit fault current component consists of alternating current (AC) transient component, direct current (DC) component, and AC component in rms. In the method, the case study uses the IEEE 14 bus standard. Short circuit fault scenarios occur in several buses which are selected based on the number of branches on these buses and the distance to other generators (power plants). As a result, buses 13 and 14 have the lowest fault current component levels than other buses, so that DG can be added to these buses.
