Kazmiruk O. The optimal control of power flows efficiency improvement in electrical networks by increasing the load capacity of transformers

A research object is a process of optimal control the flows of power in the electric networks of power systems (EPS); a research purpose is an increase of optimal control efficiency the power flows in electric networks for diminishing in them of electric power losses taking into account the technical state of transformers with regulation under the load (RUL) and their loading ability. In dissertation work applied the linear and nonlinear programming, unclear design, methods of neuron design, criterion method. Theoretical results - the method for optimal control the power flows in EPS is first offered taking into account loading ability of transformers and autotransformers from RUL, which unlike known is based on the neurofuzzy design for coefficient of their cooling system resource; the method for insensitivity area determination of optimal criterion to managing influences, which differs the account of loading ability of transformers with RUL, got subsequent development; developed method for determination of functioning quality transformers with RUL, which differs the account of power losses coefficient in electric networks, remaining resource coefficient and state of the transformers cooling system. Practical results - the algorithm for optimal control the power flows is developed in EPS taking into account the area of insensitivity of optimal criterion insensitivity area. The chart of adaptive programm-vehicle о complex ACS EPS is improved. The results of scientific researches are got in dissertation work utillized in the South-West electroenergy system with the purpose for perfection the optimization process of electric networks modes of grid and in the educational process of the Vinnytsia national technical university. Degree of introduction - job performances are inculcated in the South-West power system of NPC "Ukrenergo" (act from 13.07.2012) and in the educational process of the Vinnytsia national technical university (act from 4.09.2012). A sphere (industry of the use) is an power energy.
