摘要

针对电氢混合储能直流微网的实时运行控制问题，提出一种基于相对能量状态评估的分层控制策略。顶层控制实现微网运行模式界定及光伏单元与储能单元的参考值整定，底层控制实现对各单元的就地控制。对于多个储能单元可同时调用的模式，通过评估储能单元的相对能量状态进行功率分配，使各单元同步完成能量的消纳或释放。时域仿真结果表明，所提控制策略能够获得良好的直流母线电压控制效果，并提升光能利用率，降低储能单元的启停频次。

Abstract

Aiming at the real-time operation control problem of DC microgrid with hybrid electric-hydrogen energy storage，a hierarchical control strategy based on the relative energy state estimation is proposed. The top-level control defines the operation mode of the microgrid and sets the reference values for the photovol-taic unit and energy storage unit，while the bottom-level control realizes local control of each unit. For the operation mode allowing simultaneous scheduling of multiple energy storage units，power allocation is performed by evaluating the relative energy state of each unit，thereby enabling synchronous energy absorption or release across all units. The time-domain simulation results show that the proposed control strategy can achieve good control effect on the DC bus voltage，improve the utilization rate of solar energy，and reduce the start-stop frequency of the energy storage unit.
