本文通过对古典高峰定价模型的修正,改善了古典高峰定价基于固定比例成本函数假设,并引入高峰出现的概率及高峰持续的时间权重等情况。本文根据需求是否独立、长期与短期、高峰出现的概率、高峰的时间权重等选择一些重要的组合进行详细分析。模型的分析结果说明高峰定价能够起到削峰填谷的作用,在一定程度上减轻高峰期的用电压力。 In this paper, we modify the classical peak pricing model to improve the classical peak pricing based on the assumption of fixed proportional cost function, and introduce the probability of peak occurrence and the time-weighted peak duration. In this paper, we choose some important combinations according to whether the demand is independent, long-term and short-term, the probability of peak occurrence, the peak time-weighted, and so on. The result of the model shows that the peak pricing can play the role of cutting peak and filling the valley, to a certain extent, reduce the peak power consumption pressure.
