In a micro-grid, due to potential reverse output profiles of the Renewable Energy Source (RES) and the load, energy storage devices are employed to achieve high self-consumption of RES and to minimize power surplus flowing back into the main grid. Th... Read More about Historical data based energy management in a microgrid with a hybrid energy storage system.

An islanding detection method for multi-DG systems based on high-frequency impedance estimation (2016)
Journal Article
Jia, K., Wei, H., Bi, T., Thomas, D. W., & Sumner, M. (2017). An islanding detection method for multi-DG systems based on high-frequency impedance estimation. IEEE Transactions on Sustainable Energy, 8(1), 74-83. https://doi.org/10.1109/TSTE.2016.2582846

Active islanding detection methods are generally employed for grid-connected inverter-based Distributed Generation (DG). However, there might be mutual influences and power quality issues caused by the disturbance signal when multiple inverters are i...

High frequency impedance based fault location in distribution system with DGs (2016)
Journal Article
Jia, K., Bi, T., Ren, Z., Thomas, D. W., & Sumner, M. (2018). High frequency impedance based fault location in distribution system with DGs. IEEE Transactions on Smart Grid, 9(2), 807-816. https://doi.org/10.1109/TSG.2016.2566673

Distributed Generations (DGs) with power electronic devices and their control loops will cause distortion to the fault currents and result in errors for power frequency measurement based fault locations. This might jeopardize the distribution system... Read More about High frequency impedance based fault location in distribution system with DGs.
