【摘要】 针对孤岛直流微电网内多分布式储能单元（DBESU）DC/DC变换器采用经典V-I下垂控制存在的电流不均分和电池荷电状态（SOC）存在协同控制差的问题，提出一种基于分布式算法的储能协同控制策略。该方案通过在V-I下垂控制的基础上引入电流调节因子和SOC调节因子，对V-I下垂控制曲线进行调节，能够在不影响母线电压质量的前提下实现DBESU电流均分和SOC协同控制。仿真结果验证了所提方案的有效性和可扩展性，并在通信延迟工况下具有良好的适应性。更多还原

【Abstract】 In allusion to the problems of uneven current distribution and poor coordinated control of battery state of charge(SOC) in multi distributed battery energy storage units(DBESU) DC/DC converters using classical V-I droop control in isolated DC microgrids, a energy storage collaborative control strategy based on distributed algorithm is proposed. In this scheme, the current sharing factor and SOC balance sharing factor are introduced on the basis of V-I droop control to adjust the V-I droop control curve, which can realize the DBESU current sharing and SOC collaborative control. The simulation results verify the effectiveness and scalability of the proposed scheme, and it has good adaptability under communication delay conditions.更多还原
