Renewable energy distributed generation has been identified as the key feature of the future smart grid which will make the power system network more efficient, reliable and sustainable. To this end, power electronic devices are being increasingly added to the existing grid. These devices, due to their mode of operation, inject substantial harmonics into the grid giving rise to distortions in the voltage and current waveforms, which, in turn, leads to increased voltage stresses in transformers, machines, cables and cable accessories, and causes faster degradation of the electrical insulation, shortening the life of the equipment.

可再生能源分布式发电已被确定为未来智能电网的关键特征，它将使电力系统网络更加高效，可靠和可持续。为此，电力电子设备越来越多地被添加到现有电网中。这些设备由于其操作模式而将大量谐波注入电网，引起电压和电流波形的失真，这又导致变压器、机器、电缆和电缆附件中的电压应力增加，并导致电绝缘的更快退化，缩短设备的寿命。
