Improving the Efficiency of 6–10 Kv Power Grids of Industrial Enterprises Through Optimal Reactive Power Control

Abstract

"The article deals with improving the efficiency of an industrial power system, which is determined by the level of power losses in its elements. One of the most important methods of increasing the efficiency of power supply systems and distribution networks that ensure the transmission and distribution of electricity is to reduce the amount of electrical energy that is expended in this process. Reducing power losses in electrical grids is achieved by reducing the reactive component of the electric current, i.e., by increasing the cos φ. The Electrical Installation Code recommends, first of all, using the synchronous motors available at the enterprise. It is reasonable to solve the problem of minimizing active power losses in the power grid using the method of mathematical modeling and mathematical programming. The article presents the main features of the criterion programming method for solving a class of problems with a positive degree of difficulty, which is quite well-known in the electric power industry for solving optimization problems. We propose the method of criterion programming to solve the problem of improving the efficiency of the power grid by optimal control of the operation of synchronous motors according to the reactive power mode.
