跨区特高压直流外送优化提升新能源消纳能力研究
|
摘要
随着跨区特高压通道陆续建成投产,"三北"地区外送能力逐年增加,但新能源弃风、弃光问题并未根本解决。结合电网生产运行实际情况,对多区域间特高压直流外送功率协调优化促进新能源消纳开展研究。首先,分析了典型地区新能源弃电功率的分布特点,研究了不同区域间新能源发电功率的互补性;然后,建立了考虑跨区直流功率优化的新能源消纳能力计算分析模型;最后,针对多地区测算了跨区特高压直流互补促进新能源消纳的效果。算例分析结果表明,所提出的特高压直流优化运行方法提高了全网的新能源消纳能力,可实现多地区新能源消纳空间的充分利用。
With the operation of trans-regional UHVDC transmission channels, the outbound delivery capacity of the "Three-North"(i.e., Northeast China, Northwest China and North China) regions has been increasing year by year. However, the problem of wind power and photovoltaic power curtailment has not been fundamentally solved. Based on the actual situation of power grid operation,the coordinated optimization of multi-region UHVDC outbound deliver power is studied to promote renewable energy accommodation of multiple regions. Firstly, the distribution characteristics of renewable energy power curtailment in typical areas are analyzed, and the complementarity of renewable energy generation power among different regions is studied. Secondly, an analytical model of renewable energy accommodation capacity is established with consideration of the power optimization of transregional UHVDC transmission channels. Finally, the effects of power complementation of trans-regional UHVDC transmission channels are predicted in promoting accommodation of renewable energy for multiple regions. The case study results show that the proposed optimization method for UHVDC operation can effectively improve the renewable energy accommodation capacity of the entire power system.
