RPM-SIM-based analysis of power converter applications in renewable energy systems

This paper describes the inclusion of a power converter in the simulation of power systems that use renewable energy sources. This paper presents two major roles of the power converter. In an interconnected grid, a power converter can be utilized as a reactive power compensator or an active filter. With a battery on the DC bus, the power converter can function as an energy buffer that stores energy during peak power production and restores energy during low power production. In an isolated operation, the power converter dictates the frequency and regulates the output voltage of the system. In addition, it balances the power in the systems
