摘要
随着冀北地区新能源装机快速增长,大规模风电接入和相应配套的消纳政策
将对电网的经济运行产生重大的影响。然而冀北地区风电消纳形势严峻,大风期
与供热期重叠,系统调峰矛盾加剧,同时,针对冀北新能源消纳交易模式和辅助
服务机制的缺失则进一步限制了系统消纳能力的提升空间。因此,需要研究新能
源大规模接入后的经济性,并建立基于冀北地区源、网、荷的调峰辅助服务资源
与需求匹配模型

本文对多年来国内调峰辅助服务实践经验和国外成熟电力市场的现货平衡
机制进行了梳理和总结,并在此基础上设计适合冀北电网的调峰辅助服务正向激
励机制。建立模型测算可知在风电装机规模的不断快速增长、主力调峰资源火电
装机和用电负荷增速放缓的背景下,风火矛盾将进一步加深,风电的弃风现象将
更为普遍

为解决可再生能源消纳问题,国内外均出台了可再生能源配额制政策。本文
构建了基于多时间尺度的风电消纳能力评估技术,设计了辅助服务成本的激励机
制。测算表明该机制促进消纳间歇式能源发电,提升大规模风电接入的经济性,
实现风电消纳过程的良性运作

Abstract
With the rapid growth of renewable energy installed capacity in Jibei area,
large-scale wind power integration and the corresponding supporting policies will
significantly influence the economic operation of the power grid. However, situation
is more and more severe for wind power accomodation in Jibei area, there are two
reasons for this situation: one is the overlapping of abundant wind resource season
and winter heating period, the other is that system peak-valley regulation capability
reduces. Meanwhile, the lack of renewable energy market mode and ancillary service
mechanism further limits the accomodation level in Jibei power grid. Therefore, it is
necessary to study the economic research on large-scale wind power integration in
Jibei power grid, and establish analysis model of peak-valley regulation ancillary
service based on generation units, power transmission and load in Jibei area.
In this paper, the peak-valley regulation ancillary service practiced in China and
market mechanism of the power system in foreign countries are summarized. Based
on this, the incentive mechanism for the peak-valley regulation ancillary service is
designed in Jibei power grid. Test results show that wind power curtailment will
increase more intensely with the rapid growth of wind power installation, the
decrement of social power consumption, and the peak-valley regulation capability of
thermal units.
To solve the problem of renewable energy integration, policies of renewable
energy accomodation are introduced in this paper, a multi-time-scale wind energy
integration capacity evaluation technology is studied, a incentive mechanism taking
into account the cost of ancillary services is designed. Assessment shows that this
mechanism improves the intermittent energy accomodation level, and enhances the
profit of large-scale wind power integration.
