中文摘要

本文提出了一种基于保守功率理论(CPT)的协同控制方案,用于解决三相四线制下垂控制系统中的不平衡问题。通过CPT,微电网中电流和功率的平衡、不平衡及畸变分量可被有效识别。利用基于虚拟阻抗的控制回路,并在静止a-b-c坐标系下实现,该方案能优化微电网的电能质量。

English Abstract

A cooperative control scheme based on the conservative power theory (CPT) is proposed, which can share imbalances in three-phase four-wire droop-controlled systems. By utilizing the CPT, the balanced, unbalanced, and distorted components of the currents and powers in a microgrid can be identified. Using control loops based on virtual impedances and implemented in the stationary a-b-c frame, the im...
