随着风电场规模的不断扩大,电网接纳风电能力的限制已成为风电场规划的一个重要影响因素.为了确定系统接纳风电的最佳水平,建立了综合考虑常规机组运行成本和风电场弃风量的调度模型.引入风电接纳水平系数,从常规机组和风电场运行的经济性角度提出了一种基于粒子群算法的风电接纳水平的优化方法.对含1个风电场和10台常规机组的系统进行了计算分析.针对该风电场的12组典型出力数据分别优化得到对应的最佳风电接纳水平值并分别采用逼近法和牛顿插值法确定了系统的最佳接纳水平,在该水平下的风电出力可以使系统在一个最佳经济点运行.该比例系数可以作为风电场规划的参考.

With the enlargement of the wind farm scale, the ability of accommodating wind powers of network becomes a main factor of wind farm planning. This paper makes a scheduling model comprehensively in consideration of operation cost of conventional units and wind curtailment with a wind power acceptance level parameter to determine the optimal level of wind power acceptance. And a wind power acceptance level optimization based particle swarm algorithm is proposed in the angle of the economical operation of conventional units and wind powers. This paper calculates in a system with one wind farm and 10 conventional units and works out the optimal level of wind power acceptance respectively of the 12 groups of typical output data. And then a comprehensive optimal acceptance level is determined using approaching method and Newton interpolation. The system is in an optimal economic operation at this level and proportion coefficient can be a reference of wind power planning.
