title = "Statistical identification and classification of potential islanding precursors in a grid-connected Solar Photo Voltaic system",
abstract = "Impacts of unintentional islanding will be more pronounced in the scenario of rising distributed-generation penetration especially on distribution grids. Solar photo voltaic generation is the forerunner technology whose grid-integration is increasing significantly. This paper explores unique anomalies occurring in a solar photo voltaic system integrated with a distribution network that can potentially cause unintentional islanding and applies statistical and machine learning techniques to identify them in real time. Grid-side disturbances and complete power-balance between the inverter and loads are the conditions deemed to occur frequently in a high penetration case. These have been simulated on a modified IEEE feeder and the resulting anomalies cross-verified in emulation and real-time simulation. Multivariate statistical techniques and a support vector classifier have been applied to identify the explored anomalous currents. The classification results show promising application towards a new predictive islanding detection logic inside solar inverters however the actual relay delay in tripping a breaker and the inverter's capability to trip before it on sensing a potential precursor to accidental islanding needs to be tested in real time.",
