| description | The development and utilization of distributed renewable energy (DRE) is beneficial to achieving the goal of “double carbon”. However, due to the strong volatility and uncertainty of DRE, its high-proportion penetration to distribution networks may bring operation challenges such as voltage violation. In this regard, a hybrid control method based on hybrid Petri-net is proposed to address the serious overvoltage/undervoltage issues. The method includes two layers, where the upper layer performs an intelligent transformer gear switching control strategy triggered by node voltage exceeding conditions, and the lower layer adjust the active power of virtual power plants based on power voltage sensitivity. In this way, the voltage would be adjusted in the coarse-fine hybrid manner. The proposed method could tap into the potential of utilizing the low-voltage distribution network's own transformers and distributed adjustable resources for aggregation and regulation. It is of great significance in promoting the large-scale consumption of DRE. |
