BORGES VASCONCELLOS, Davel; PEREZ ABRIL, Ignacio and LEON MARTINEZ, Vicente. Modelation of effects on reactive power compensation in secondary power systems. Ingeniare. Rev. chil. ing. [online]. 2012, vol.20, n.2, pp. 160-169. ISSN 0718-3305. http://dx.doi.org/10.4067/S0718-33052012000200003.
The inconveniences of the reactive power are presented and from this are carried out the mathematical models of its economic effects applicable to secondary power systems. The effects taken into account are: the costs of the capacitors banks, the expenses of paying-off to the banks, the expenses of power losses to the banks, the benefits for the improvement of the power factor, included the reduction of power loss in the system, as well as the benefits for the liberation of the load capacity, to the case of companies where the latest aspect can represent an economic attractiveness. For the analysis after and before compensation, are consider load flow algorithm witch load model adjust. According to electrical tariff structures in Cuba, these effects are integrated in a function of economic analysis, for this case the net actual value, which serves as base for the position of the optimization problem, which can derive in the correct selection of the devices compensators.
