Electromagnetic Transients Simulation for Renewable Energy Integration Studies

Grid interface of renewable energy based distributed generation requires satisfying the interconnection requirements stipulated by the local distribution utility. Detailed testing of protection and control systems is required to ensure conformity to wide ranging interconnection requirements such as fault ride through capability, protection against islanding, harmonics and voltage flicker limits. Electromagnetic transient simulation is a powerful tool for performing such studies with very detailed models of power electronics converters, controllers and protection systems. Furthermore, the simulated transient waveforms can be recorded and played back into actual hardware using real time signal playback equipment to verify correct operation.
