峰谷电价和尖峰电价是调节电力需求的有效措施之一,适用于电力改革任何阶段,二者设计的基本原则均为平均电价水平不变。尖峰电价在峰谷电价的基础上发展而来,其基本理念是,一年内尖峰负荷仅在少数几日的部分时段出现,通过对这些时段针对性地实施极高的尖峰电价,能有效地减少或转移高峰负荷,取得比常规峰谷电价更好的效果。我国峰谷电价比已不低,调整的重点在于时段,如分季节设置。我国已实施的尖峰电价本质上仍是峰谷电价,未来必须大幅缩短执行时段并拉大尖峰与其他时段的价差。此外,还需建立峰谷电价、尖峰电价动态调整机制,并采取必要的配套措施。
Peak-valley electricity price and peak electricity price are one of the effective measures to regulate electricity demand. They are applicable to any stage of electricity reform. The basic principles of the two are the same as the average electricity price level. The basic idea of spike price, which is based on the peak-valley electricity price, is that spikes occur in only a few days in a year. Targeted high spikes in these periods can effectively reduce Or transfer the peak load, get better than the conventional peak-valley price effect. China’s peak-valley price is not low, the focus of the adjustment is time, such as sub-seasons set. The peak electricity price that has been implemented in our country is still essentially the peak-valley electricity price. In the future, the implementation period must be drastically shortened and the spread between the peak and other periods must be drastically reduced. In addition, the need to establish peak-valley electricity price, peak power price dynamic adjustment mechanism, and take the necessary support measures.
