Abstract

The availability and cost of fossil fuels, natural disasters, aging infrastructure, climate change, and rising electricity consumption have affected the current power grids. One of the most practical solutions for achieving green and reliable energy is the use of microgrids. The stability of microgrids dominated by electronic converters presents several challenges. Among the problems encountered are the absence of physical inertia, delay in detecting islanding, loss of stability associated with the transition between operating modes and variations in the load power. To overcome these challenges, this study presents a new robust control strategy based on active disturbance rejection control (ADRC). It is suitable for both islanded and connected operation modes with a single control, without islanding detection and synchronization algorithms. The effectiveness of the control strategy was demonstrated through simulations and a comparative analysis with conventional droop control. Flexibility of the transition was also ensured. The proposed control strategy is successfully validated using a TI C2000 DSP TMS320F28335 microcontroller. This research was published in the IEEE Access journal "Seamless Transition Between Microgrid Operation Modes Using ADRC Without an Islanding Detection Algorithm nor PLL".
