In order to improve the steady-state performance of the bus voltage of the energy-storage flexible multi-state switch(E-FMSS)DC side and suppress the DC voltage fluctuation when the connected feeder fails
this paper proposes a PID controller with improved fuzzy linear self-disturbance resistance controller(LADRC) instead of the outer ring of DC voltage. The improved fuzzy LADRC
based on the derivation model
adds an additional proportional link in parallel in the integral link of the disturbance estimation of the linear extended state observer (LESO) to enhance the accuracy of the disturbance estimation
and considers the LESO for system total disturbance estimation error compensation. The online optimization of fuzzy LADRC parameters is achieved by combining the active anti-disturbance parameter tuning method of the improved beetle antennae search. Simulation results show that when the feeder connected by E-FMSS fails
the strategy proposed in this paper can significantly suppress the DC voltage fluctuation of E-FMSS
the active power of each port is smooth transition
