摘要
风能是一种可再生无污染的绿色能源。风电开发技术成熟,是现今最具开发前
景的新能源之一。风电产业迅速发展,越来越多的风电场相继投入运行。但由于风
能随机性、间歇性的特点造成了风电场输出功率的波动,且这种波动往往与电力系
统负荷不一致,因此,风电场的装机容量并不能替代同等容量的常规火电。
抽水蓄能电站是储存电能的一种方式。通过抽水蓄能电站的抽水蓄能和放水发
电,可以实现风电场原始可利用风能在时间和空间上的重新分配。
本文建立了风电—抽水蓄能联合供电系统。在介绍了风力发电和抽水蓄能基本
理论的基础上,建立了联合供电系统的保证出力最大模型,以最大保证出力来衡量
风电场的替代容量;在此基础上,结合电力系统负荷,提出了联合供电系统容量替
代最大模型,直接得出风电场的替代容量;在基于容量替代最大模型仿真结果的基
础上,本文还提出了调峰出力最大模型,一方面使得风电场的替代容量最大,另一
方面增加了电力系统的调峰能力,同时又使得常规火电能够平稳的运行。仿真计算
结果表明,风电场在配置一定容量的抽水蓄能电站后,无论从保证出力方面还是从
实际运行方面,都可以替代部分常规火电,因此具有一定的经济效益和社会效益。
这将有利于提高风电在电力系统中的份额,促进我国风电产业的发展。

Abstract
The wind power is a kind of renewable green power resources. Now, the wind
power is one of new energy which has the most development prospect because of its
mature development technology. The wind energy industry has developed rapidly in
recent years and a lot of large and medium wind parks have been put into production one
after another. But the nature of intermittence and randomness of wind energy leads to
constant fluctuation of the power output of wind farm, and this fluctuation is often
inconsistent with the power system load, therefore, the installed capacity of wind power
could not displace the same capacity of conventional thermal power.
The pumped storage power station is a way of storing energy. Through the
pumped-storage and water power generation, it could be achieved that wind farms can
make use of wind energy in the original time and space redistribution.
This paper establishes bined power supply system of wind-pumped storage
power station. After introducing the basic theory about wind power generation and water
power storage, this thesis builds the largest model of the ensure output of the
wind-pumped storage power station, the capacity of wind power alternative could be
measured by the largest ensure output. Based on this, combining of power system load,
the maximum capacity of alternative model of bi
