Active islanding detection methods involve the solar inverter injecting small disturbances or signals into the grid and observing the response. . Islanding occurs when part of a power network, disconnected from the main grid, is solely powered by some Distributed Energy Resources (DERs), and presents voltage and frequency conditions that are maintained around nominal values. In general, only unintentional islanding is studied, as intentional. . The rapid and effective islanding detection and disconnection of the microgrid are significant for preventing equipment from failure and safeguarding humanity's safety. To address the drawbacks of active methods and passive methods, an intelligent islanding detection strategy based on. . This paper suggests an island prediction model based on an enhanced light gradient boosting machine algorithm and the fusion of various electrical feature values to address these issues. These methods can be broadly categorized into passive, active, and hybrid. . The invention discloses an adaptive detection method for an isolated island of a grid-connected photovoltaic power generation system, comprising the steps of: (1) judging whether the effective value of the voltage at the grid-connected point reaches the protection threshold, and if so, outputting a. . The classical problem of islanding detection in distributed generation falls into the commonly used categories known as passive, active, and hybrid techniques.
