摘要：
With the increasing penetration of green energy such as wind energy and photovoltaic energy in the traditional power system, conventional AC grid cannot transmit the high capacity of electricity in a long distance, which makes the interconnection of flexible multi-terminal DC network become a future direction of regional power network and wind power consumption. Firstly, the control strategies of flexible multi-terminal DC network are studied. Then, each intelligent agent is set up at every converter station to propose the intelligent distributed control scheme for flexible multi-terminal DC network. Finally, a typical four-terminal flexible DC grid system is set up for simulation, which shows that the control strategy can combine the advantages of centralized control with distributed control, in which each agent will be able to plan and make appropriate decisions, and the exchange of information with other agents via the TCP/IP protocol, as well as the fast response in the emergency situations for the system failures or large disturbances, reducing time delay of communications and optimized calculation for upper grid agents. © 2017, Electric Power Automation Equipment Press.
