Modelling of aggregated operation of power modules in low-voltage DC-grids
The paper focuses on small-signal analysis of aggregated operation of the low-voltage DC-grids comprising various power and load modules. Complex impedances, which can be identified experimentally, represent the internal structure of power converters and may become a reason for voltage instabilities while being gathered together in the DC-grid using cables. The paper proposes ideas to analyze and forecast possible resonance issues of parallel operation of power modules in the test model of the 380V DC-grid and make recommendations in order to avoid them.
