Power edge cloud network and security protection method thereof

The invention relates to a power edge cloud network and a security protection method thereof. The power edge cloud network comprises a sensor for collecting service data, an aggregation node for performing aggregation processing on the service data, and an edge cloud center for managing and controlling the whole power edge cloud network, the method comprises the following steps: a supervision aggregation node in the aggregation nodes performs behavior characteristic acquisition on surrounding aggregation nodes to be evaluated, and performs trust calculation on the aggregation nodes to be evaluated based on a preset supervision mechanism so as to identify abnormal nodes in the aggregation nodes to be evaluated; and acquiring processing data of the abnormal node, and transmitting the processing data to the edge cloud center, so that the edge cloud center diagnoses an abnormal reason based on a deep learning algorithm. According to the method, the abnormal nodes in the power edge cloud network can be quickly det
