An Experimental Evaluation of Object-oriented Linear Solvers for Newton-Raphson Power-Flow

The paper reports on object-oriented (OO) power system programming and applying sparse matrix storage and operations to power system network matrices. An OO model of the power system network is described as well as the OO Newton-Raphson power-flow algorithm. A discussion on storage capacity and algorithm speed is presented. The numerical experiments were performed on four standard test networks widely used for power system studies. The obtained results are discussed and compared with respect to the actual time in which the calculation was carried out. Sparse matrix storage and sparse matrix algebra was used in the experiment.
