摘要: DC Microgrid attains popularity in integrating renewable energy sources and batteries. It also has the potential to achieve higher efficiency than ac power grid with optimized flow. In this paper, a general dc microgrid is modeled based on cluster of nodes, which includes constant renewables generation, droop-controlled voltage source different kinds load. Then flow solved for optimization. A restoration method consensus algorithm used restore deviation from droop characteristic. An enhanced current regulator adopted guarantee accurate load sharing even under influence sensor drift line resistance. tie control proposed regulate directly increase system at light condition. All considered methods only need local information its nearest neighbor thus expendability guaranteed. Simulation experiment results are provided validate methods.
