基于拉格朗日乘子自适应下垂控制的低压直流微电网并联分布式能源配电损耗抑制

This article presents a Lagrange multiplier-based adaptive droop control to mitigate distribution power loss of parallel-connected distributed energy resource (DER) systems in dc microgrids. The distribution power loss comprising line loss and converter loss can be modeled as a quadratic function of the output currents of the DER systems, which can be optimized by the tertiary-layer Lagrange multi...
