【摘要】：随着风电、光伏等新能源在传统电力系统中渗透率的增加,常规的交流电网已不能满足远距离、大容量输送电能的需要,柔性多端直流电网将成为区域互联和风电消纳的发展方向。首先对柔性多端直流电网的控制策略进行研究;然后,在每个换流站都设置一个智能体,提出柔性多端直流电网的智能分布调控策略;最后,搭建一个典型的四端柔性直流输电系统进行仿真。仿真结果表明,该控制策略能够同时兼顾集中式控制和分布式控制的优点,每个智能体都能够计划并制定适当的决策,通过TCP/IP协议与其他智能体交换数据,在环境突变(系统故障或者大扰动)的情况下迅速做出反应,减少通信延迟以及上级电网智能体优化计算的时间损耗。
[Abstract]:With the increase of permeability of wind power, photovoltaic and other new energy sources in traditional power system, conventional AC power grid can not meet the needs of long-distance, large-capacity power transmission. Flexible multi-terminal DC network will become the development direction of regional interconnection and wind power absorption. Firstly, the control strategy of flexible multi-terminal DC network is studied. Then, an agent is set up in each converter station, and the intelligent distributed control strategy of flexible multi-terminal DC network is proposed. Finally, a typical four-terminal flexible direct current transmission system is built for simulation. The simulation results show that the control strategy can simultaneously take into account the advantages of centralized control and distributed control. Each agent can plan and make appropriate decisions, exchange data with other agents through the TCP/IP protocol, and react quickly in the event of environmental mutations (system failures or large disturbances). Reduce the time loss of communication delay and optimization calculation of superior grid agent.
