A fixed-point current injection power flow for electric distribution systems using Laurent series
نویسندگان
چکیده
This paper proposes a new power flow (PF) formulation for electrical distribution systems using the current injection method and applying Laurent series expansion. Two solution algorithms are proposed: Newton-like iterative procedure fixed-point iteration based on successive approximation (SAM). The convergence analysis of SAM is proven via Banach theorem, ensuring numerical stability, uniqueness solution, independence initializing point. Numerical results obtained both proposed compared to well-known PF formulations considering their rate convergence, computational time, stability. Tests performed different branch R / X ratios, loading conditions, initialization points in balanced unbalanced networks with radial weakly-meshed topologies. Results show that computationally more efficient than PFs, being ten times faster backward–forward sweep algorithm. • novel systems. Linearization Convergence stability theorem. Proposed at least three sweep.

A Fixed Point Method for Power Series Computation
This paper presents a novel technique for manipulating structures which represent infinite power series. When power series are implemented using lazy evaluation, many operations can be written as simple recursive procedures. For example, the programs to generate the series for the elementary transcendental functions are almost transliterations of the defining integral equations. However, a naiv...

A Theory of Solvability for Lossless Power Flow Equations – Part I: Fixed-Point Power Flow
This two-part paper details a theory of solvability for the power flow equations in lossless power networks. In Part I, we derive a new formulation of the lossless power flow equations, which we term the fixed-point power flow. The model is stated for both meshed and radial networks, and is parameterized by several graph-theoretic matrices – the power network stiffness matrices – which quantify...
