Optimization of Radial Electric Network 110 kV

Abstract

In short-term planning and operational management of the electric network mode, the tasks of voltage regulation are solved, which ensure the maintenance of standard voltage indicators and reduce the loss of active power. To combine these tasks, a mathematical model of network mode optimization has been formed, taking into account technical limitations. The target function of the model is the minimum total loss of active power in the network. Technical requirements are taken into account in the form of nodal power balances of active and reactive power, restrictions on the area of changing mode parameters. The computer implementation of the model is used to analyze the mode of the radial section of the 110 kV electric network with variations in the substation load over a wide range. The optimal level of voltage and transformation coefficient of the transformer, providing a minimum amount of load and constant power losses in the network section, under various loads, are determined. The power limit at which the maximum permissible transmission voltage should be maintained is determined.
