摘　　要：本文以浙江电力市场的实际运行数据为基础 ,对电力市场中的现货电价进行了统计分析。解释了电力市场中电价的一些异常波动现象 ,包括负电价、零电价出现的原因。研究了最高限价出现的频率及其与系统负荷的关系 ,并从“市场势力”的角度分析了统计结果。发现交易日与交易日之间各时段电价变化的相关程度较高 ,并由此探讨了进行短期电价预测的可能性。另外 ,评估了浙江电力市场现货电价的总体水平及整个市场的运行状况。This paper presents the analysis of spot prices based on data of Zhejiang electricity market.The senario of negative spot price was discussed.It was found that the cap price apeared very often in Zhejiang electricity market and this was regarded as a signal of the existence of market power.Price duaration curve was formulated.In addtion,a new method of short term price forcasting was put forward.
