Abstract
The analysis and design of the droop control applied to the bi-directional distributed generator in the dc microgrid are presented. The effects of line resistance on power sharing and voltage regulation performance are analysed. In order to interpret the complicated line configuration, the voltage sensitivity analysis based on the power flow analysis is derived. Based on this analysis, a droop control design method is proposed to improve the droop control performance. The design method is implemented through an PSCAD/EMTDC simulation. In a simulation model of dc microgrid, three bidirectional distributed generators, three loads, and one non-dispatchable distributed generators are connected to the 5-bus network model, and the improved performance are verified.
