摘　　要：双母线结构直流微电网的主要控制目标是稳定各级母线电压、维持整体系统的功率平衡,传统的阻性下垂控制不能很好地协调这2个控制目标。提出一种基于离散分组一致性算法的双母线直流微电网自适应下垂控制策略。所提策略基于Java Agent开发框架(JADE)平台多代理系统,通过网内以及网间的互通协议,在弱通信网络条件下根据分组一致性协议使各级母线实现区域功率自治。搭建由JADE、Mac Sim JX、Simulink组成的混合仿真平台,仿真验证了所提控制策略的有效性。The main control objectives of the DC microgrid with two buses are to stabilize the bus voltage at all levels and maintain the power balance of the whole system,but the traditional resistance droop control can＇t coordinate the two control objectives well,so an adaptive droop control strategy is proposed based on the discrete group consensus algorithm,which,based on the multi-agent system in the JADE（Java Agent DEvelopment framework） and the interworking protocol in the subnets and among subnets,makes the buses at all levels realize regional power autonomy according to the group consensus protocol in the weak communication network condition.The hybrid simulation platform composed of JADE,Mac Sim JX and Simulink is built to verify the effectiveness of the proposed control strategy.
