Malogulko J. Optimization of the functioning of the renewable energy sources in the local electrical systems

Object of the research - normal modes of distribution electrical grids with renewable energy sources. Research methods - used methods of mathematical modeling and numerical methods, statistical methods of information processing used for analysis of simulation results, the methods of linear and nonlinear programming algorithms used to create optimal search solutions tasks, steady modeled and analyzed using the method of node voltages. The aim - to improve the efficiency of renewable energy in electrical distribution networks by improving the methods and means of optimizing the transportation of electricity generated. Theoretical results - first proposed analytical optimality conditions of transport power schemes in local electric systems by criterion of minimum power losses and operational control laws developed by means of reconfiguration schemes accession of renewable energy based on the concept of Smart Grid; the first time the method of optimizing the daily schedules of renewable energy sources in accordance with the projected schedule for complex loads optimality criterion that takes into account the quality and power losses; improved method for determining the optimum installed capacity for a given place of joining renewable energy sources in the local electrical system; further developed the method of determining the optimal place of joining renewables capacity given the local electrical system by criterion of minimum power losses. Practical results - based on the research, solved the problem of optimization of renewable energy sources in the local electrical systems, is to select the right configuration options accession schemes and renewable energy, automation control their operation as part of the local electric system will reduce the cost and increase the volume of electricity generated. Level of implementation - the results of the research are implemented at Public Utility Company "Vinnytsyaoblenergo" and in the educational process Vinnytsia National Technical University. Sphere (branch) of application - electrical power engineering.
