基于国际先进技术的风电调度研究与实践

随着我国风电高速发展,不断提高系统风电消纳水平、保证含大规模风电系统安全运行成为电网调度机构面临的重大挑战。在分析总结欧美国家先进风电调度运行经验基础上,剖析了我国大规模风电并网运行的难点,研究了适应于我国电源运行特性的基于先进技术的风电调度方法,并通过实际运行数据表明,综合采用实时监测、风电功率预测、风电日前计划、实时控制、供热监测等多种先进技术的风电优化调度措施可以大大提高我国风电消纳水平。

Research and Practice of Wind Power Dispatch Based on International Advanced Experience

With the rapid development of wind power in China, it is the most difficult challenges for grid operation organization to increase wind power utilization rate and to improve the safety level of the system. This paper analyzed the international wind power dispatching technology such as Europe and America. The true difficult points of Chinese electrical system for operating large-scale wind power are presented. Moreover, the wind power dispatching optimization technology is studied. Thereafter, the wind power dispatching supporting systems are constructed in the SGCC management range to aid the dispatching decision. The system includes real-time supervision, wind power forecasting, day-ahead schedule, real-time control and heat supply monitoring. The practice in the SGCC management range indicates that all of the methods improve the wind power ratio in the system greatly.
