    摘 要:为充分发挥微电网中分布式资源的协同构网调节能力,实现频率与输出电压一致性稳定、有功功率合理分配等控制目标,结合构网下垂控制特性,提出了一种基于多智能体一致性算法的分布式二次协同控制策略。该策略通过分布式发电资源中二次控制器间的通信交互,设计了基于含领导者的领导跟随一致性控制架构,实现了全局频率与输出电压跟随领导者目标一致性恢复;同时考虑发电单元承担能力的差异,实现了发电单元间有功功率的精确共享和优化分配。仿真结果验证了所提控制策略的有效性,并讨论了相应二次控制增益对结果的影响。

    Abstract: In order to give full play to the collaborative grid-forming regulation capabilities of distributed resources in microgrids and achieve control objectives such as consistent stability of frequency and output voltage, as well as reasonable allocation of active power. Based on the droop control characteristics of networked systems, this paper proposes a distributed secondary coordinated control strategy based on a multi-agent consistency algorithm. This strategy facilitates communication and interaction among secondary controllers within distributed generation resources and is designed using a leader-follower consensus control framework, and achieves the global frequency and output voltage to consistently follow the leader,s target. Moreover, it takes into account the differences in the capabilities of generating units, achieving precise sharing and optimal allocation of active power among them. The simulation results substantiate the effectiveness of the proposed control strategy and elucidate the impact of the associated secondary control gains on the overall performance.
