Systém pro optimalizaci provozu elektrické distribuční sítě

Abstract

Today, the European electrical-power industry is undergoing big changes, and a large part of them relates to electrical distribution networks. The electrical distribution networks are undergoing a transformation into modern "smart" distribution networks. Modern smart distribution networks will be equipped with many measuring and control devices, and communication networks transferring data between all those measuring and control devices and the control computer. On the control computer, there will be software running in a close-to-real-time regime. Using data from those measuring devices, this software will determine how the individual control devices installed in the distribution network should be set up so that the distribution network works as best as possible – i.e., as stable, quality, and operationally robust as possible. This dissertation presents software that has the ambition and ability to be the controller of a modern distribution network. This software is equipped so that under normal operating conditions of the distribution network it can control this network optimally, i.e., with minimal voltage fluctuations across the network, optimal use of local production and storage capacity, minimal active-power losses in individual network elements or with the highest possible available transmission capacities. The control process’ preferred goals for a given network can be determined by the network operator by setting the weights of individual observed variables. If one or more faults occur on elements of the controlled distribution network, this software will provide the network operator with instructions on how to proceed in eliminating the faults so that the total amount of electrical energy not supplied to local customers is as low as possible.
