【摘要】：分析了帶恒功率負(fù)荷的級聯(lián)系統(tǒng)在平衡點穩(wěn)定的條件,以兩源和兩負(fù)荷級聯(lián)系統(tǒng)耦合為例,通過求解耦合系統(tǒng)的特征值表明,2個參數(shù)相同的級聯(lián)系統(tǒng)耦合不能提高其穩(wěn)定性。探討了抑制直流微電網(wǎng)振蕩的2種策略:一種是通過引入源側(cè)變換器參數(shù)的多相性并配合耦合控制參數(shù)的取值來抑制振蕩;另一種是通過引入耦合控制的延遲量來消除振蕩。仿真結(jié)果驗證了2種策略的可行性和有效性。
[Abstract]:The stability condition of cascade system with constant power load at the equilibrium point is analyzed. The coupling of two sources and two loads cascade system is taken as an example. By solving the eigenvalues of the coupled system, it is shown that the coupling of two cascaded systems with the same parameters can not improve its stability. Two strategies to suppress the oscillation of DC microgrid are discussed: one is by introducing multiple parameters of the source-side converter. The phase property is combined with the value of the coupling control parameters to suppress the oscillation. The other is to eliminate the oscillation by introducing the delay of coupling control, and the simulation results show that the two strategies are feasible and effective.
