What are the challenges of microgrid control?
One of the critical challenges of microgrid control is to ensure that the microgrid operates stably and efficiently, even in the presence of uncertainty and disturbances. This operation uses advanced control algorithms, such as model predictive control (MPC) and robust control [ ].
What factors affect microgrid control?
Factors such as stability and operational control are of paramount importance in both modes of operation due to considerations such as frequency, voltage, optimal power transfer, and islanding detection, among others. The control topology and stability of microgrid applications and system modelling vary depending on the specific applications.
