The task of autonomous power sharing in a micro-grid is usually achieved by decentralized droop control on individual interface power converters, which may suffer from the dependence on output line impedances. Inaccurate reactive power sharing will occur under strongly non-uniform line impedances. Due to inherently distributed and heterogeneous nature of the micro-grid, it becomes an ideal platform...

Since distributed interface converters (DICs) embedded in the isolated micro-grid (MG) usually have low inertia, high penetration of DIC-based MGs may result in poor voltage and frequency response when the grid experiences large disturbances. The synchronverter is proposed recently in which the DIC mimics conventional synchronous generators (SGs) by designing parameters of the SG into the droop control...
Due to inherent distributed and heterogeneous nature of the micro-grid, the micro-grid becomes an ideal platform for consensus-based control. Conventionally, power sharing in a micro-grid is achieved by autonomous P-f and Q-V droop control on individual inverters, which suffers from the dependence on output line impedance. Inaccurate reactive power sharing will occur under strongly non-uniform line...
Micro-grid is a system with various distributed energy sources integrated. Due to its inherent distributed and heterogeneous nature, the micro-grid becomes ideal platform for consensus-based multi-agent control. Conventionally, power sharing in a micro-grid is achieved by autonomous P-f and Q-V droop control on individual inverters, which suffers from lack of frequency restoration mechanism and dependence...
Power system preventive control is dominated by generation rescheduling. Other preventive control actions are rarely mentioned in the literature. This paper presents a transient stability preventive control design that takes series compensation into account. The design methodology is aided with the ‘If-Then’ rules extracted from a trained multilayer perceptron (MLP) artificial neural network (ANN)...
