摘要
基于相变材料特性建立相变储能水箱热力学模型;分析建筑负荷特性,建立建筑室内温度动态模型;运用基于Wasserstein距离的分布鲁棒算法,建立风电预测误差不确定集。提出考虑相变储能与建筑蓄能特性的微网两阶段分布鲁棒优化调度模型。模型第1阶段是基于风电预测信息,制定日前调度计划,第2阶段考虑风电预测误差,在最恶劣概率分布条件下,获得日内调度计划。最后,运用算例分析相变储能水箱与建筑蓄能特性对风电消纳以及系统调度的影响,并验证分布鲁棒模型的有效性。
A phase change heat storage thermodynamics model is first built based on the characteristic of phase change material.By analyzing the feature of building load,a dynamic model of indoor temperature is established.A wind power forecast error ambiguity set is made by using the Wasserstein distributionally robust optimization.Then,a two-stage distributional robust coordinated dispatch model for microgrid considering phase change heat storage and the characteristic of building energy storage is proposed in this paper.In the first stage of the model,a day-ahead economic dispatching is formulated based on the prediction of wind power.In the second stage,the real-time economic dispatching is obtained by taking the prediction error into consideration at the worst-case probability distribution.Finally,through the simulated cases,the influences of phase change heat storage and the characteristic of building energy storage on wind consumption and system economic dispatching has been analyzed.
