When the microgrid’s energy generation exceeds all the loads on it, the microgrid can charge its energy storage devices, such as batteries, via a bidirectional AC/DC converter. The use loads (both AC and DC) are connected to a common AC bus (backbone network). Microgrids can also send out (export) energy to the utility power grid.
Abstract: With the application of the Internet of Things (IoT), smart charging piles, which are important facilities for new energy electric vehicles (NEVs), have become an important part of the smart grid.
Since the smart charging piles are generally deployed in complex environments and prone to failure, it is significant to perform efficient fault diagnosis and timely maintenance for them.
In this article, a real-time fault prediction method combining cost-sensitive logistic regression (CS-LR) and cost-sensitive support vector machine classification (CS-SVM) is proposed. CS-LR is first used to classify the fault data of smart charging piles, then the CS-SVM is adopted to predict the faults based on the classified data.
