| Abstract: | In order to reduce the operation loss and cost of active distribution network and improve the consumption capacity of distributed generation,the automatic power compensation method of active distribution network based on edge calculation is studied.Design the automatic management platform of active distribution network including terminal equipment layer,edge computing layer,information management layer and cloud computing layer,monitor the operation status of each equipment of active distribution network in real time,use the edge cloud cooperation mode to realize the collection,storage and pre-processing of equipment information data by the platform,and combine the objective function of minimum line total network loss.A bilayer programming automatic power compensation model of active distribution network is established from the cloud computing layer.After calculating the model through the edge computing layer,the automatic power compensation of active distribution network is completed.The example analysis results show that this method can effectively reduce the total line loss of active distribution network,improve its operation economy,improve the consumption level of distributed generation,have good convergence performance,high precision and efficiency,low CPU consumption,and ensure the low cost,safe and stable operation of active distribution network. |
