【摘要】：针对天然气的居民用户制定合理的峰谷分时气价,能有效地削峰填谷,从而保证燃气管道安全稳定地运行。本文构建用户需求响应和满意度函数,并在此基础上建立以最小化最大峰负荷和峰谷负荷差,及最大化用户满意度为目标的需求侧峰谷分时气价优化模型。采用蚁群算法对模型进行求解,该算法收敛性较好,同时也避免局部最优的缺点。算例结果表明,在兼顾公平与效率的前提下,峰谷分时气价模型能有效地降低最大峰负荷和峰谷负荷差,同时存在最优的峰、平、谷价格,使得用户满意度最大;另外本文也验证了模型的有效性及可行性。此方法为天然气合理定价机制的建立及政策的制定提供了理论依据。
[Abstract]:According to the reasonable peak-valley time-sharing gas price for the residents of natural gas, it can effectively cut the peak and fill the valley, so as to ensure the safe and stable operation of the gas pipeline. In this paper, the user demand response and satisfaction function are constructed. On the basis of this model, a demand side peak and valley time-sharing gas price optimization model with the goal of minimizing the maximum peak load and peak valley load difference and maximizing customer satisfaction is established. Ant colony algorithm is used to solve the model, and the convergence of the algorithm is good. At the same time, the shortcoming of local optimum is avoided. The result of example shows that the peak and valley time-sharing gas price model can effectively reduce the maximum peak load and peak valley load difference under the premise of both fairness and efficiency, and at the same time there are optimal peak, equal and valley prices. In addition, this paper also verifies the validity and feasibility of the model. This method provides a theoretical basis for the establishment of a reasonable pricing mechanism and the formulation of policies for natural gas.
