摘要
中国已进入能源发展的调整阶段,利用新能源发电是调整能源发展的重要趋势,其中风光互补发电是新能源发电的新兴方向,而分析风光输出功率的特性是评估风光互补发电系统对电网影响的重要内容。因此,笔者通过计算风光输出功率概率密度分布、输出功率波动量概率密度分布,以及分布函数的特性,分析了风光输出特性,并基于实测功率数据的算例,验证了风光互补发电能够提高新能源入网的利用率,削弱风电对电网的影响,风光互补发电可行。
China has entered an adjustment period of energy development, providing a new direction for new energy, the significant part of energy adjustment, which is wind and solar hybrid power generation. To evaluate the influence of wind and solar hybrid system on power grid, the key point is the analysis of the characteristics of wind and solar output power. This paper explains the output characteristics of wind and solar hybrid system on the basis of the calculation of the probability density distribution of wind and solar output power, wind and solar output power variations and the characteristics of the distribution function. The analysis of the example based on the real measured power data shows that wind and solar power generation, which is proved to be feasible, can improve the utili- zation of grid - connected new energy, weaken the influence of wind power on the grid.
