One of the assessments for the reliability of the electric power system is the ability to serve the load needs continuously. There are no blackouts because there is an imbalance between the supply of electric power and the needs of the consumer load. The additional loads on the consumer side must be followed by the addition of power plants. Renewable energy is an alternative to increase the supply of electrical energy and does not damage the environment. However, the addition of new power plants can cause an increase in the contribution of short-circuit fault currents. The purpose of this paper is to compare the topology for the addition of renewable energy. The topology used is centralized and distributed generation. The renewable energy used consists of solar farm and wind farm. The best topology is a topology that produces lower short-circuit currents. Short circuit analysis methods used include the analysis of AC transient components, DC components, and AC rms components. Steady state short circuit simulation results show that distributed renewable energy contributes higher fault current than centralized renewable energy. Likewise, in the analysis of fault currents using the transient AC component, DC component, and AC component in rms value method, distributed renewable energy contributes higher fault current peak value than centralized renewable energy. © 2021 IEEE.
