Impact of allocation factors on electric power system control

The paper presents a brief description of the graph algorithms to calculate allocation factors of power flows, loads and losses. The authors analyze the applicability of these factors to solving the problems of a posteriori analysis of nodal prices, estimation of generators´ contribution to the network voltage drop, identification of generators, that affect negatively the sensitivity of the steady state equations system solutions´ to a change in the external factors. The suggested approaches are illustrated on the examples of a test power systems.
