Active Power Loss Distribution In Power Flow Based On The Holomorphic Embedding Method

The Holomorphic Embedding Load flow Method (HELM) is an approach aimed at solving the power flow problem based on complex analysis techniques, resulting into a deterministic, non-iterative, and initial-estimation independent method, as opposed to well-known iterative algorithms, which are prone to incorrect solutions in absence of appropriate initial estimations. Distributed Slack Bus (DSB) models, which are a realistic mean of distributing active power losses among system generators instead of assigning the losses to a single generator, are formulated for iterative methods only. Thus, the present paper proposes a novel approach for a DSB model suitable for HELM. This novel approach is tested by using an IEEE 118-bus benchmark system, yielding very similar results to those obtained using a conventional Newton Raphson method.
