Abstract:

According to the current and voltage constraints of the droop control micro-sources under fault conditions,a fault control strategy based on the virtual impedance current limiting and droop limiter voltage regulation was proposed,the equivalent fault model of the droop control micro-sources under the positive and negative sequence network was established as well.The simulation results based on MATLAB/Simulink verify the correctness and rationality of the fault control strategy and fault model.

Key words: droop control, micro-grid, fault control strategy, fault model, current limit
