含大规模热泵的配电网异步迭代分布式三相潮流计算

Distributed three-phase load flow accommodated large scale heat pumps based on asynchronous iteration scheme

随着分散式热泵大规模推广应用,考虑热泵模型的三相潮流计算是分析配电网电压水平的重要工具。由于不同投资主体的增量配电网快速发展,考虑到保护数据隐私、通信延迟等因素,实现集中式潮流计算和同步迭代的分布式潮流计算都很困难。首先给出基于隐阻抗法的含大规模热泵的三相潮流计算方法,然后给出基于矩阵分裂模式的异步迭代分布式计算模式,实现适用于配电网的分布式潮流计算方法。通过IEEE 123节点系统验证了算法的有效性。

With deployment of large scale distributed heat pumps,three-phase load flow considering heat pumps impact is a basic tool to analyze distribution network profile.Due to the rapid development of incremental distribution networks with different investment entities,it is very difficult to achieve both centralized power flow calculation and synchronous power flow calculation considering the factors such as data privacy protection and communication delay.Firstly,three-phase load flow with large scale heat pumps is proposed based on implicit node impedance method.Secondly,asynchronous iterated load flow is proposed based on matrix-split scheme.The proposed method is suitable for distribution network distributed load flow.Finally,the proposed method is validated with IEEE 123 test feeder.
