Virtual Smart Network Cell

Abstract

The local power generation facilities were interconnected into national, regional, continental and nowadays intercontinental networks. A lot of problems and tasks occur, like the controllability, the integration of the renewable sources, decrease of the spread over of the outages. The present answers for the challenges are mainly extensive, the networks are enlarged, the traditional polluting generation capacities, the power plants, storages are developed and extended. Beside the “Electrical globalisation” occur local civil initiatives, the higher integration level of the grid resulted the need for new structures, as microgrids and locally controllable Smart Grids. Our aim to develop structural and operational solutions for decrease the problems mentioned above, make the supply sustainable. Beside the centralized intercontinental networks occur the microgrid, smart grid and “power quality island” solutions. Our basic concept is to develop a new virtual smart network cell haven’t applied yet. It forms virtual microgrid island, uses the existing network, connected on IP base, aggregates small generators and consumers Through this solution the load will be balanced, the dynamic of the operation will be decreased, the load-generation balance will be realized on local level, we move toward the sustainable power supply.
