Modeling and analysis of dynamic response of an industrial power system with renewable energy

Abstract

This paper studies the dynamic response of an industrial power system with insertion of renewable energy sources. The case study is modeled using the software ETAP, and different scenarios of interest are simulated. The disturbances that affect the correct operation of the system and its stability are analyzed. Load shedding is evaluated and the critical times for fault clearance, generator and motor start-up are determined. Taking into account the interaction between independent systems, the automatic operation of protection devices and switches is simulated by applying selectivity criteria, as well as the effect on the motor starting and re-acceleration system through dynamic analysis. Finally, the load flow is analyzed, obtaining the optimal way to transmit energy.
