| 摘 要： | 电力系统调峰平衡是其维持静态稳定的关键,在风电大规模接入的形势下,亟需研究风电接入对电力系统调峰平衡的影响。以适用于含风电电力系统调峰平衡计算的数学模型及算法为基础,研究了风电接入对电力系统调峰平衡的影响,并提出相应计算方法。在此基础上,以区域电网为例,根据其实际情况设计电网的调峰运行方式以及风电接入方式,基于电网实际数据,仿真计算了其在3种风电接入方式下的调峰盈余,分析了风电大规模接入对电网调峰平衡的影响,结果表明,风电大规模接入将对电力系统的调峰平衡带来显著负面影响,而影响程度与风电接入电网的方式密切相关。

| Abstract: | The peak load balance of power system is the key lo maintain its sialic stability.Wind power is urgent to be studied when accessed into the power system on a large scale.Based on mathematical models and algorithms applicable lo the calculation method on the peak load balance of power system with wind power,the corresponding calculation method is put forward.First design the operation mode of peak load shaving and the mode of wind power access based on the actual situation of this regional power grid,then simulate and calculate the surplus of peak load shaving in three modes of wind power access based on the actual data of the grid.Last,analyze the impact on peak load balance of power system coming from the access of wind power.The results shows that large-scale wind power access will bring notable＇ negative influence on peak load balance ol power system,the degree of influence closely relates to the modes of wind power access. |
