Abstract

This letter presents a novel non-iterative power flow solution for radial distribution systems. In the pursuit of a linear power flow solution that seamlessly integrates into other power system operations, an approximate solution via complex linearization of non-holomorphic functions, making no assumptions about the network's parameters was developed. This approach can be readily adapted to different load models, and its accuracy is comparable to other established conventional radial load flow analysis tools.
