The paper presents a proposal for the implementation of smart grid concepts in Slovenian distribution networks. The most relevant technologies and concepts are identified, an implementation plan is proposed and costs are evaluated on the basis of the expenses for research, demonstration and large-scale implementation. The results show, that the long-term cumulative investments in distribution grids would be lower with the introduction of smart grids when compared to the traditional approach. Implementation of smart grids could enable to lower planned network investments from 4.2 billion € to approximately 3.7 billion € (for the period from 2011 until 2030), resulting in a reduction of 500 million €.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 10090836Operation of distributed generation has a significant impact on the voltage quality in the low-voltage and medium-voltage electrical networks. When dealing with the power quality problems, different solutions are possible which differ by the necessary investments in the primary and secondary energy infrastructure. The paper provides an overview of the key technologies of ICT systems and at the same time pinpointing out their advantages and disadvantages. The paper also covers the topics on the subject of standardization, network control and the role of mobile operators in smart electricity networks.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 9886548Smart grid offers new and advanced types of control. The document describes the operation of four concepts of smart grids; virtual power plant, demand-side management, ancillary services and infrastructure for electric vehicles. In the report these four concepts are addressed in detail and their specification is suggested in terms of required input parameters and data flow.
