WebSecond, the hierarchical optimization of CLDs is realized. Moreover, as device parameters in the lower coupled area are selected first, it is helpful to reduce the uncertainties in the remaining parameter optimization of CLDs. Thus, the calculated and optimal efficiency of CLDs in the whole DC grid is improved.
