Parallel interleaved converters for high power renewable energy systems present stability issues at the LCL resonance frequency. A multisampled measurement and filtering strategy is proposed to stabilize the system based on the capacitor voltage derivative active damping, overcoming its limitations for low switching power converters. The effects of the delays on the stability of the active damping strategy would be analysed. The solution developed is robust against grid inductance variations, ensuring the fulfilment of the stringent harmonic grid codes. [--]
