Development of a Methodology for the Management of Electric Distribution Grids

Abstract

During implementation of distributed generation in Western Europe and North America the following problems were identified: reduction of reliability of power supply to consumers, reduction of power quality due to harmonic distortions caused by the use of low-frequency inverters, management of microgrids during transition to isolated operation, related to the limited possibility to control distributed generation plants and the specificity of renewable energy sources. An effective solution to these problems is the creation of a distributed smart grid control system.This paper proposes an approach to create a decentralised control system with self-tuning, self-configuration and self-healing functions without the use of a single decision-making unit. The implementation of such a control system should lead to: to increase the reliability of power supply; improvement of economic performance of micro-energy systems; to increase the flexibility and ability to expand the system.
