考虑用户满意度变化和差异的智能小区代理商定价及智能用电服务计划
摘要：售电公司或代理商希望利用峰、谷、尖、平电价，制定可灵活调节的电价，推进智能小区与电网的灵活互动，获得更大收益。前提是不增加用户用电总成本，且满足其满意度要求，但更应该顾及不同用户的满意度变化和差异。因此，提出考虑用户满意度变化和差异的智能小区代理商定价及智能用电服务计划双层模型。上层以代理商利润最大为目标，制定用户电价并传至下层。下层以用户用电费用最低为目标，计及用户满意度变化及差异约束，生成智能用电计划并传回上层，通过上下两层混合整数规划迭代求解该双层模型。算例结果表明，考虑满意度变化和差异后，增加了代理商收益，降低了用户用电费用，减小了负荷曲线峰谷差。智能小区代理商定价可调节用电市场的灵活性，改善电力负荷峰谷差曲线特性，考虑用户满意度变化和差异后可为用户提供更加个性化的智能用电服务。
Abstract:In order to obtain higher earnings, power suppliers or agents hope to enact flexible adjustable electricity price by use of peak-valley price and the prices under other load situations to promote the flexible interaction among intelligent residential areas and distribution network. The premise of such a scheme is not increasing the user’s total cost of electricity consumption and their demand on the satisfaction degree should be met, however, the change and discrepancy among different consumers’ satisfaction should even more be considered. For this reason, a bi-level model of smart community agent pricing and smart electricity service plan, in which the change and difference of consumers’ satisfaction degree were considered, was proposed. In the upper level of this model the maximized profit of the agent was taken as the objective and the user electricity price was enacted and transmitted to the lower level. In the lower level of this model the lowest users electricity charge was taken as the objective and considering the constrains of change of user’s satisfaction and difference the smart power utilization plan was generated and sent back to the upper level, and the proposed bi-level model was solved by the iteration of upper and lower level mixed integer programming. Results of computing example show that after taking the change and difference of satisfaction into consideration, the earning of the agent is increased and the user’s electricity charge is decreased, and the difference between peak and valley in the load curve is decreased as well. The pricing of smart community agent can adjust the flexibility of power supply market, improve the characteristics of power load peak-valley difference curve, and provide user more personalized smart electricity service after considering the change and difference of user satisfaction.
