分析了华东日前和月度电力市场静态限价机制的特点,总结国外电力市场限价方法,介绍了动态限价机制的基本概念和方法,比较了动态限价与静态限价机制的利弊。针对华东月度电力市场,提出了分季节动态限价机制和模型;针对日前电力市场,提出了分日以及分节点的动态限价机制和模型。月度限价的实际算例表明,分季节月度动态限价机制合理,限价水平能够体现市场供求关系的季节性。 The characteristics of the static electricity price limit mechanism in East China and East China were analyzed. The methods of price limit in foreign electricity markets were summarized. The basic concepts and methods of the dynamic electricity price limit mechanism were introduced. The advantages and disadvantages of the dynamic electricity price limit and the static electricity price limit were compared. Aiming at the monthly electricity market in East China, a dynamic price-limiting mechanism and model for sub-seasons are put forward. According to the electricity market in the past, the dynamic limit-price mechanism and models for sub-day and sub-node are proposed. The actual monthly price limit shows that the monthly dynamic limit pricing mechanism is reasonable and the price level can reflect the seasonal relationship between supply and demand in the market.
