Today's energy grids face an increasing number of decentralized and renewable energy sources as well as growing e-mobility. Therefore, reliable grid monitoring becomes a key element for a sustainable grid operation. Traditional grid monitoring concepts are either fully manual, need a detailed system model, or rely on computationally heavy machine learning concepts. However, with the given complexity of the energy grid, a model-free and context-aware monitoring approach can save resources and efforts. Recently, we introduced the Confidence-based Context-Aware Condition Monitoring (CCAM) system and successfully tested it on two different industrial use-cases: a hydraulic circuit and an AC motor. In this paper, we enhance CCAM for a third, entirely different industrial use case, an energy grid, by introducing two extensions - a continuous reevaluation and a state mooring approach. Furthermore, we present a new Smart Grid monitoring methodology on top of CCAM, paving the way for new real-time grid control systems. We evaluate our approach based on historical load data from a low voltage grid section. Our results show that characteristics of a daily load profile can be learned and outliers can be detected.
