摘要: |
为了解决以风电为代表的大规模间歇性电源的接入给互联电网有功调度与控制带来的问题,提出利用广域范围内风电资源的时空互补性来降低风电功率的波动性。基于某区域电网各省风功率数据,分析风电时空互补性对系统动态备用、调峰、频率控制、联络线功率控制的影响,提出在更大范围内利用间歇式能源互补性的多级协调调度模式。从调度计划的多级协调编制、多时间尺度协调、区域电网统一频率控制、需求响应资源充分利用等方面分析了这种调度模式的特点,指出了这种调度模式与现有调度模式的区别。 |

Abstract: |
Large-scale integration of intermittent renewable energy brings great challenges to power system’s operation and control. The reasonable utilization of time-space complementary characteristics of wind energy can effectively decrease the effect of wind power fluctuation. Based on the wind power output data of one regional power grid, this paper analyses the influence of complementary characteristics of wind power on dynamic reserve, peak shaving, frequency control and tie line power control. Then, a multi-level coordinated scheduling and control scheme is proposed, featured with multi-time scale coordination, multi-area resource sharing, unified frequency control and full advantage of demand response. Finally, the differences between the new scheduling scheme and the existing scheduling mode are discussed. |
