Abstract

A method of controlling electrical power systems coupled to an electrical connection point includes obtaining carrier signals and fundamental waveforms from electrical power systems coupled to at least two renewable energy sources, generating pulse width modulation (PWM) signals using the carrier signals and the fundamental waveforms while interleaving carrier signals, fundamental waveforms, or a combination of carrier signals and fundamental waveforms of the electrical power systems, and driving grid side converters of the electrical power systems with the PWM signals.
