Decomposed load flow

摘要

A decomposed load flow is presented. Decomposing the load flow model into a PV node submodel and a PQ node submodel is implemented. A diagonal PV node submodel and a decoupling of the PV and PQ node submodels are proposed. The radial connections of generator transformers and their small resistances are taken into account. The dimension of the active load flow matrix is reduced without sacrificing its sparsity. Fast convergence and computation were obtained for data from an actual system.
