摘要：
The island microgrid can absorb clean energy locally and realize zero carbon power supply within a certain range. However, since the island microgrid is not supported by a large power grid, the high proportion of distributed energy is connected by power electronic converters, which leads to its lack of inertia. It is difficult to achieve stable frequency, reliable power supply and efficient consumption of new energy at the same time. Aiming at the island microgrid with energy storage and hydrogen fuel cell, combining the advantages of master-slave operation mode and peer to peer operation mode, a hybrid operation mode based on coordinated control of grid-forming supply is proposed. Energy storage and hydrogen fuel cell are controlled grid-forming supply, which adopts constant voltage constant frequency control and virtual synchronous generator control respectively. Other clean energy adopt constant power control as the grid-following supply. In the power coordination algorithm, the energy storage state of charge is taken as the reference for the power regulation of hydrogen fuel cell, and the power differential term is introduced to improve the dynamic regulation performance, so as to realize the coordinated operation of weak communication between energy storage and hydrogen fuel cell. MATLAB/Simulink simulation results show that the proposed method can take into account the frequency stability, operation reliability and new energy efficiency of the island microgrid, which proves the correctness and effectiveness of the hybrid operation mode and power coordination strategy. © 2022, Power System Technology Press.
