基于风光互补出力特性的可消纳容量研究

Consumptive Capacity Research Based on Wind-Solar Hybrid Characteristics

针对传统风电消纳方法不适用于风光互补地区消纳容量求解的问题,提出一种快速有效计算新能源可消纳容量的方法。首先在现有风电、光伏的全年出力数据的基础上,结合风电、光伏规划比例得到风光互补全年出力数据;然后计算得到风光全年同一小时有效出力值;最后结合夏、冬季典型日和供暖小负荷日3个典型日每小时系统调峰裕度,计算得到每小时可消纳风光装机容量,综合比较分析得到可消纳新能源容量。以2019年张南地区为算例,验证了所提算法的快速有效性。

The traditional wind power consumptive method does not adapt to the solution of consumptive capacity in the wind-solar hybrid area,a new method is therefore proposed in this paper to rapidly calculate the consumptive capacity of renewable energy in order to develop and utilize the wind and solar resources in a healthy way.Firstly,based on the existing wind and solar output data of a whole year in North Hebei area,the whole-year wind-solar hybrid output data are obtained according to the planned ratio of wind and solar power;and then,the effective output of wind and solar power in the same hour of a year is calculated;Finally,based on the power system’s peak shaving margin for every hour of three typical days,including the typical day in the summer and winter respectively and the small heating load day,the consumptive installed capacity of wind and solar power per hour is calculated,and the consumptive capacity of renewable energy is obtained through comparative analysis.Through a case study of South Zhangjiakou area in 2019,the effectiveness of the proposed method has been proved.
