论文摘要
如今，对电力客户的态度已经改变，因此他们不再被视为静态玩家。客户的行为标识对于建立现代电力系统至关重要。本文利用客户风险避免系数来建模其消费行为。通过系数，使用实用程序函数的概念来测量电力消耗的价值。公用事业功能是微观经济学中的重要概念，它可以衡量客户的偏好并解释理性消费者将如何做出消费决策。根据公用事业功能，制定了经济负载模型和客户福利功能。负载模型用于估计价格弹性和电力需求的收入弹性。结果说明的是风险避免系数增加，消费者从消费中获得了更高的满意度。如果风险厌恶系数比单位更大（低），则电力消耗将是补充（替代）。对于单位风险避免系数，交叉价格弹性将为零，这意味着消费与其他时期需求无关。结果说明了电价上涨的收入增量对消费的效果。因此，为了研究电力消耗，应同时考虑价格和收入变化。
Nowadays, attitudes towards electricity customers have been changed, so that they are no longer considered static players. The customers behavior identification is vital for establishing modern power systems. This paper utilizes the customers risk aversion coefficient to model their consumption behavior. Through the coefficients, the value of electricity consumption is measured employing the concept of the utility function. The utility function is an essential concept in microeconomics that measures customers preferences and interprets how a rational consumer would make consumption decisions. Based on the utility function, an economic load model and the customers welfare function are formulated. The load model is utilized to estimate price elasticity, and income elasticity of electricity demand. The results illustrated as the risk aversion coefficient increases, the consumers achieve more satisfaction from the consumption. Electricity consumption will be complement (substitute) if the risk aversion coefficient is greater (lower) than the unit. For the unit risk aversion coefficient, the cross-price elasticity will be zero, which means the consumption is independent of the other period demand. The results illustrated electricity price increment neutralizes the income increment effect on consumption. Hence, to study electricity consumption, the price and income variations should be considered, simultaneously.
