3、拟定将继续优化销售电价的分类结构,减少电价的交叉补贴,建立有利于引导用户合理用电,促进节能减排的电价体系。2010年10月,发改委出台了关于居民生活用电实行阶梯电价的指导意见(征求意见稿)。发改委针对电量分档和电价制定给出了两个参考方案,这些举措都表明阶梯电价即将在全国范围内推行。当前我国电力市场还尚未完全建立起来,电价体系仍然不完善,因此,在电力市场环境下,由季节性电价、分时电价、峰谷电价等主要组成的销售电价,在我国开展缓慢,一些相关的外部环境和技术条件等配套措施也还不成熟。对于我国电力企业来说,不同的用电市场,应该是根据不同细分用电市场的价格弹性来确定经济性上合理的定价方式。通常来说,收入
4、较低的群体通常对电价很敏感,容易因电价上涨而减少电力的消费,所以价格弹性大;而高收入消费群体则不太在乎电价的上涨,当然价格弹性就较小。对于我国居民来说,目前的居民用电平均定价,并没有考虑到消费群体的差异。按照目前的电力平均定价或平均提价,那么低收入居民将会减少用电量,由于电价相对较贵;而高收入居民则增加用电量,电价相对便宜。目前实施的对不同消费量实行统一电价的模式,居民的平均电价低于供电成本,居民基本上是在高峰期用电,用电量越多峰就越高,供应成本就越贵。在这种情况下,要么通过制定较高的工业电价进行交叉补贴,要么通过国有电力企业的亏损进行补贴,实质上更多地补贴给了高收入居民,因为高收入家庭用电最
5、多。实行阶梯电价,除了能反映社会的公平,还更加有利于鼓励居民节约用电、减少能源的浪费。本文将针对阶梯电价如何对居民产生效应,考虑季节性的阶梯电价如何缓解电网负荷高峰期间的供电紧张局面,以达到引导居民“节约用电、节能减排”的目的。关键词:阶梯电价;概率论;季节性;效应ABSTRACTOver the years, the electricity market reform greatly accelerate the pace of scientific and reasonable and transparency of government pricing system preliminar

And the step and tariff design presents a reference scheme, two herald a ladder electricity price is introduced across the country
8、. Current our country electric power market has not yet fully established, electricity price system is still not perfect, therefore, power market environment, the main content of the sales price seasonal peak valley electricity, time-sharing electricity price, electricity price, etc., in China is sl

Generally speaking, the low-income groups usually is sensitive to price, easy due to the increase in power tariff reduce electricity consumption, price elasticity; And high income consumers dont care much about electricity price rise, the price elasticity is small.For residents, residents of

According to the current average price or the average price of electricity, the low-income residents can reduce power consumption (relatively expensive), whereas high-income residents to increase consumption (ch

Of unified electricity current of different consumption pattern, the average price is lower than the cost of supply, the consumer is basically on peak electricity, power consumption peak is higher, the more cost of supply, the more expensive. In this case, or through high cross-subsidisation
