Comprehensive distribution power flow: modeling, formulation, solution algorithms and analysis

摘要: The objective of this work was to develop a formulation and an efficient solution algorithm for the distribution power flow problem which takes into account detailed extensive modeling necessary use in automation environment real world electric system. The formulations three classes existing algorithms radial systems were generalized extended handle comprehensive already presented context more traditional but less methods, such as Newton-Raphson Implicit $Z\sb{bus}$ Gauss. includes unbalanced three-phase, two-phase, single-phase branches, constant power, current, impedance loads connected wye or delta formations, cogenerators, shunt capacitors, line charging capacitance, switches, three-phase transformers various connection types. The explored are: network reduction backward/forward sweep fast decoupled methods. Within each classes, new developed methods include general formulation. Proofs convergence are also provided. In addition algorithms, compensation method used weakly meshed encompass networks with loops, multiple sources, PV buses. This can be applied conjunction any solvers. Termination solver, at iteration, is based on adaptive criterion. A correction step developed. All proposed evaluated compared test data from systems. range size 63 buses over 1000 most class shown require significantly computation than both Gauss typically showing improvement factor three.
