Abstract
The method proposed in this paper controls the power flow of the meshed DC power system using a DC Power Flow Control Converter (PFCC), and reduces the fault current that occurs in the case of a short circuit in a DC circuit. It is a method to lower the fault current flowing through the DC circuit breaker and thus to reduce the stress applied to the circuit breaker. The proposed PFCC is a Dual Active Bridge (DAB) Converter consisting of a DC/AC power converter connected in parallel with the DC system, a high-frequency transformer that transforms voltage, and a DC/AC power converter, and It consists of a full bridge converter that is connected in series with a DC line and outputs a constant voltage and a reverse voltage, and controls the voltage of the grid line. In this paper, simulation was performed by applying PFCC to a mesh-type DC power system through MATLAB/Simscape, and performance and feasibility were verified through Cassie method to analyze the characteristics of DC circuit breakers.
