摘要:

电力市场中普遍存在价格钉现象。结合近年来的相关文献对价格钉进行了综述：首先分析自由竞争的电力市场中电价的基本特点，并从经济学角度分析价格钉产生的原因，影响价格钉的供给与需求方面的主要因素，然后重点对价格钉的预测方法和控制途径进行了评述，对比了各种预测方法的优缺点及适用面，以及各种可能的控制途径。文章最后探讨了今后的研究方向。

Abstract:

There are price spikes in most of electricity markets. This paper reviews the literature in recent years on price spike. First ,it analyzes the character of electricity price in a competitive markets, and introduces why price spikes occurred and which demand and supply factors affected spikes from economical prospect, and then forecasting model and controlling way of price spike are compared, the merit/demerit of each kind of model, way and their applying situation are given．Finally，further works are presented.

Key words: price spike power market forecast model control electricity price
