A Distributed Collaborative Method of Small Thermostatically Controlled Load Based on Block Chain

为充分挖掘海量分散式小型温控负荷(TCL)的聚合调控潜力,文章设计了一种基于区块链的温控负荷分布式协作架构和控制方法。该方法基于温控负荷设备的开关状态、温度变化规律所对应的物理模型,综合考虑用户对不同舒适度区间的设定行为,进行精细化设备分群聚类。根据用户温度设定特征将用户分为不同的类别群组,将不同类型的温控负荷划分为优选组、备选组、非选组进行管理,并结合某台区负荷曲线、温度参数作为训练数据进行仿真验证,深入分析不同类别用户模式迁移后的温度曲线变化趋势。分析结果表明,所提出的协作方法相对于传统的运行方式在适应风电出力方面具有明显的优势。

In order to make full use of the aggregation regulation potential of massive distributed small thermostatically controlled load(TCL),this paper designs a distributed collaborative architecture and control method of TCL based on block-chain.This method is based on the physical model corresponding to the switching state and temperature change law of TCL equipment,and comprehensively considers the user’s setting behavior of different comfort ranges to carry out fine equipment clustering.The user group is divided into different categories according to user temperature setting characteristics including optimal group,candidate group,non-candidate group.Load curve and the temperature parameters of a certain area are selected as training data for simulation.Different category temperature curve change trend of user mode after the migration is analyzed,and the results show that the collaborative method proposed in this paper has obvious advantages in following wind power curves compared with the traditional operation mode.
