Semeniuk N. Influence of overlap fluxes on active power loss in transit electric energy grid

The object of research is normal operating modes of electric energy systems. The aim of the work is to develop methods and means of calculation the transmission and distribution grid active power losses caused by inhomogeneity of the transit energy system. Theoretical result is the developed method of allocating the active power losses caused be trasit overlap fluxes among all the participants of electric energy market allowing for inhomogeneity of electric networks of energy systems. Also existing methods of power fluxes optimal control in electric networks were improved by taking into account their mutual impact. Practical result is the offered method which gives the opportunity to determine the influence of transit and inner power fluxes on power losses in the transit system. Due to this method, the procedures of calculation of additional power losses caused by mutual and transit power fluxes resulting from mutual impact of operating modes of inhomogeneous networks of electric energy system. This allows for operative estimating the efficiency of technical means aimed to decrease the power losses caused by overlap power fluxes and stimulating the ways of power losses decreasing in networks of separate energy companies. Value and address of power losses components enable the grounded pricing for covering the actual transit power losses in electric networks. The degree of implementation - the results have been implemented in 'Pivdenno-Zahidna' power system and in the scientific process of Vinnitsa Techical University. Scope (area) of - power engineering.
