【摘要】:隨著分布式能源的興起和電力電子技術(shù)的發(fā)展,相比交流配電網(wǎng),直流配電網(wǎng)擁有更大的發(fā)展?jié)摿ΑT撐氖紫葘χ绷髋潆娋W(wǎng)的拓撲結(jié)構(gòu)、控制方法以及模式切換問題進行了闡述。其次,為了有效解決配網(wǎng)系統(tǒng)中復(fù)雜的模式切換問題,簡化控制流程和優(yōu)化潮流控制,文中提出了一種適用于直流配電網(wǎng)的電壓控制策略,該策略使各端電壓源換流站均具有維持電壓和調(diào)節(jié)功率的能力,其中主站作為功率平衡節(jié)點,并為系統(tǒng)提供參考電壓。最后,在PSCAD/EMTDC中建立了雙端和三端直流配電網(wǎng)結(jié)構(gòu)的仿真模型。通過仿真驗證了該直流配電網(wǎng)電壓控制策略的有效性。
[Abstract]:With the rise of distributed energy and the development of power electronics technology, DC distribution network has more potential than AC distribution network. In this paper, the topology, control method and mode switching of DC distribution network are discussed. Secondly, in order to effectively solve the complex mode switching problem in distribution network system, simplify the control flow and optimize power flow control, a voltage control strategy suitable for DC distribution network is proposed in this paper. The strategy makes the terminal voltage source converter stations have the ability to maintain voltage and adjust power. The main station acts as the power balance node and provides the reference voltage for the system. At last, the simulation model of two-terminal and three-terminal DC distribution network is established in PSCAD/EMTDC. The effectiveness of the voltage control strategy is verified by simulation.
