摘　　要：随着大规模风电场的建设和并网,电源(风电)与电网之间的尖锐矛盾逐渐显现。一些电网由于输电能力的限制,导致部分新建机组不能并网或已投运风电机组弃风,这种电网被定义为有待用风电机组且传输能力受限的电网。对于电网调度员来说,只有入网风电机组的装机容量是可调度的。由于风电的波动特性,即使知道用于传输风电的电网传输空间,也难以决定应该接入多少风电机组以充分利用电网传输空间。文中通过对风电波动特性的分析,提出了源网协调调度方法。该方法可在保证电网安全的条件下,最大限度地利用电网用于传输风电的空间,以提高电网和风能利用率。With the construction and incorporation of large-scale wind farms,the contradiction between the source（wind generators） and the grid is highlighted increasingly.Due to grid constraints,some installed wind generators cannot be incorporated into grids,and the wind curtailment happens in some commissioning wind generators.This grid can be defined as ＂a transmission constrained grid with surplus wind generators＂.For a grid dispatcher,only the specific capacity of wind generators can be dispatched.Even if the grid transmission space used to transmit wind power is known,due to the fluctuation characteristics of wind power,it is difficult to determine how much specific capacity of wind generators is suitable for sufficiently utilizing this space.This paper proposes a method to coordinate the source and the grid by the fluctuation characteristic analysis of wind power.The method can maximize the grid transmission space for wind power to improve the utilization of grids and wind energy while ensuring the grid security.
