摘要(Abstract)：
在含电压源换流器和全控型开关器件为基础的VSC-HVDC中,引入风光互补发电技术则是一种新能源与新技术的结合,这种结合不仅能够解决了传统高压直流输电中的许多技术难点,同时也加强了地区能源资源优化配置,提高了系统供电的可靠性。在VSC-HVDC系统的基础上,考虑风光资源不稳定的特性,建立了风光接入的最优模型,通过最优潮流理论分析,求解风光接在不同节点的极限并网容量,并以30节点的算例进行验证,证明该方法的有效性。
In VSC-HVDC system with voltage source converter and full control switch device, the introduction of hybrid wind/PV power generation combines new energy and new technology, which can not only overcome the technical difficulties of traditional HVDC transmission system but strengthen the optimization of regional energy resources allocation and improve power supply reliability. Based on the VSC-HVDC system, an optimal model for wind and PV power integration is established in consideration of wind/PV resource instability. Through theoretical analysis on optimal power flow, grid integration capacity limits of different nodes connected to wind/PV power are solved. In addition, the example of node 30 is validated to demonstrate the effectiveness of the method.
