Hierarchical Power Flow Control Strategy and Algorithm for Multi-terminal Interconnected AC/DC Distribution Network
摘要
Abstract
With the development of DC distribution system , the network structure and operation mode of traditional distribution system have greatly changed . The AC/DC hybrid distribution network will be dominant in the future and poses a new challenge to power flow control and the AC/DC hybrid algorithm . For this reason , a hierarchical power flow control strategy is proposed to carry out orderly voltage control . At the first layer , DC load sharing is realized by the bidirectional converter with droop control , and DC bus voltage is controlled according to the droop control curve , at the second layer , local voltage balance is regulated by the distributed generator , while at the third , regional voltage is controlled by the voltage regulator . Secondly , the Gauss‐Newton hybrid algorithm is proposed according to the characteristics of the AC/DC hybrid distribution system to improve the convergence performance of the algorithm . Finally , the test results on a modified IEEE 123‐bus system show the validity and correctness of the control strategy and algorithm proposed .关键词
