摘　　要：市场条件下零售电价相对固定而批发市场电价和负荷需求经常波动,使配电公司面临较大的风险。实行批发市场电价与零售电价联动,是减小配电公司市场风险的有效办法。分析了配电公司的主要运营业务及其成本,说明了传统分时电价在市场条件下的特点,提出通过分时电价方法实现零售电价与批发电价联动,并建立了相应的数学模型。通过对模型的求解,给出了最优分时电价的表达式,对模型中涉及的市场参与者的类型、负荷弹性等因素进行了讨论。最后通过算例验证了该方法对实现电价联动的有效性。In competitive market, retail prices are comparatively fixed, while wholesale prices and load demand are variable, which lead distribution utilities facing huge risks. Co-related change of retail prices and wholesale prices is considered as an effective way to evade risks. This paper analyzes the main tasks and costs of distribution utility, as well as the characters of time-of-use (TOU) pricing in market environment. A TOU pricing method is presented to relate wholesale and retail prices, based on that, mathematical models are set up and the optimal solutions are derived. Different types of participants, elasticity of load with presented models are also discussed. Simulation results show the feasibility of proposed method.
