| Summary: | To ensure the reliable and efficient operation of the DC microgrid, the control system needs to be well designed so that the system can meet various operation requirements, including stability, power sharing and voltage drop limitation. However, it is challenging in designing the control strategy which considers multiple-operation requirements, especially when facing the DC microgrid with complex multi-bus architecture. To address this problem, this paper presents an improved droop control towards the multiple-operation requirements of multi-bus DC microgrid, such as decentralized stability, power sharing and drop limitation of bus voltage. Firstly, the system stability is analyzed based on the mixed potential theory, and a decentralized stability criterion is proposed. Then, based on the proposed stability criterion and the potential function reshaping, an improved droop control strategy is designed to realize these multiple requirements. Finally, the effectiveness and the general applicability of the proposed criterion and the proposed control are verified by case studies. |
