摘　　要：风电出力过程的随机、不连续、不可控特点,导致风电难以被电网所吸纳。利用水力发电快速、可调节的优点,通过二者联合补偿调节,可弥补风电出力的缺点。首先提出了风电与水电联合补偿调节的原理;其次确定补偿调节的目标,提出联合补偿调节的两个原则,即电力电量补偿平衡原则和避免弃水补偿原则;最后,给出不同情况下水电补偿风电的计算方法,获得水电补偿能力。以上述理论为基础,分析了2015年西北电网水电与风电互补状况。通过该研究,为大规模风电并网发电提供了一个可行途径。The output ofwindpower plant is random, discontinuous and uncontrolled, so it is difficult to be absorbed by power network. Hydropower is advantageous in response rapid and adjustable; the disadvantage of windpower can be made up by compensation operation of hydropower plant and windpower plant. Based on analysis of the principle of compensation operation, this paper first demonstrates some objective and rules for such compensation, namely, output-electricity balance rule, and abandoned-water minimization rule Then we present calculation methods for different conditions by using these rules and complementation calculations for joint operation of hydropower and windpower plants of the Northwest Grid in 2015. This work would provide a theoretical basis and practical approach to compensation operation of vower plants.
