基于用户成本选择用户范围的分时电价最优策略

Optimal Time-of-Use Price Strategy With Selecting Customer's Range Based on Cost

传统的分时电价政策忽略了用户参与分时电价政策的意愿,且用户电价电量响应行为建模未考虑用户调整用电行为成本,为此提出基于用户成本选择用户范围的分时电价最优策略。分析用户改变用电行为所产生的调整成本与节省用电费用的关系,推导分时电价机制下用户电价电量响应行为模型。当用户改变用电行为后,其生产成本高于实行分时电价前的电费,则对用户参与分时电价政策的意愿评估为零,不纳入分时电价实施范围。仿真及实验结果显示,与不选择用户范围的传统分时电价模型相比,该模型能够反映用户调整用电行为过程,科学选择参与分时电价政策的用户范围,实现电网和用户的总效益最优。

The traditional time-of-use price policy ignores the user’s willingness. And the modeling of users’ response behavior does not consider the cost for users’ adjustment of electricity consumption, and the range of users cannot be selected theoretically.Therefore, this paper proposes an optimal time-of-use price strategy for selecting user’s range based on cost. The relationship between the extra cost generated by the user’s adjustment of electricity consumption behavior and the saved electricity consumption cost is analyzed. Then a model for electricity price and electricity response behavior under the time-of-use electricity price mechanism is derived. When the user’s production cost after changing the electricity consumption behavior is higher than the price before the timeof-use price is implemented, the user’s willingness to participate in the time-of-use price policy is evaluated as zero, and the user is not included for implementation of the time-of-use electricity price. The simulation and experimental results show that compared with the traditional time-of-use electricity price model that does not select the customer’s range, the proposed model can reflect the adjusting process of user’s electricity consumption behavior, and can scientifically select the use’s range to participate in the time-ofuse electricity price policy, and can achieve the best total benefits for the power grid and users.
