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

With deployment of large scale distributed heat pumps, three-phase load flow considering heat pumps impact is a basic tool to analysis distribution network profile. Since there are numerous three-phase distribution network nodes and communication delay impact etc., centralized load flow and synchronous iterated load flow is difficult to achieve. 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 matrixsplit scheme. The proposed method is suitable for distribution network distributed load flow. Finally, the proposed method is validated with IEEE 123 test feeder.
