A new DC fault current limiter-based circuit breaker for DC microgrid clusters is proposed, offering low complexity, cost, and power losses. Time-domain simulation studies in MATLAB/Simulink environment were conducted to assess the performance of the proposed method, validating the analytical expressions and demonstrating the effectiveness of the DC fault current limiting and clearing strategy.
A new DC fault current limiter (FCL)-based circuit breaker (CB) for DC microgrid (MG) clusters is proposed in this paper. The analytical expressions of the DC fault current of a bidirectional interlink DC/DC converter in the interconnection line of two nearby DC MGs are analyzed in detail. Meanwhile, a DC fault clearing solution (based on using a DC FCL in series with a DC circuit breaker) is proposed. This structure offers low complexity, cost, and power losses. To assess the performance of the proposed method, time-domain simulation studies are carried out on a test DC MG cluster in a MATLAB/Simulink environment. The results of the proposed analytical expressions are compared with simulation results. The obtained results verify the analytical expression of the fault current and prove the effectiveness of the proposed DC fault current limiting and clearing strategy.
