摘要
为解决直流微电网中各微源功率分配精度与母线电压稳定之间的矛盾,提出了一种基于离散一致性算法的非线性下垂控制策略。根据线路阻抗对控制效果的影响,通过非线性变化的下垂电阻的曲线来平衡功率分配精度和母线电压稳定,并且应用离散一致性算法对各微源电压进行调整,减少母线电压的压降。最后,通过建立MATLAB/Simulink仿真验证了基于一致性算法的非线性下垂控制策略的有效性和优越性。
In order to solve the contradiction between the power distribution accuracy of each micro-source and the voltage sta-bility of the busbar in DC microgrid,a nonlinear droop control strategy based on discrete consistency algorithm is proposed.According to the influence of line impedance on the control effect,power distribution accuracy and busbar voltage stability are balanced by the curve of nonlinearly varying droop resistance,and the discrete consistency algorithm is used to adjust the voltage of each micro-source,to reduce the voltage drop of the busbar voltage.Simulation results by MATLAB/Simulink demonstrate the effectiveness and superiority of the proposed nonlinear droop control strategy based on the consistency algorithm.
