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 €.

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.

COBISS.SI-ID: 9921364The paper focuses on evaluating the value of savings of the SmartGrids implementation in Slovenian distribution system network. Additional investments in the distribution system in order to connect distributed generation (DG) sources are needed for the achievement of Slovenia's environmental commitments. SmartGrids concept gives us an option to lower investment costs in the long term. However, additional investments in R&D and new equipment will be needed in the middle term of 10 years. This paper is the result of research in the Slovenian SmartGrids Roadmap (distribution network)
B.03 Paper at an international scientific conference
COBISS.SI-ID: 36024325In line with the long-term national energy policy, the share of renewable energy sources is expected to rise. Without an upgrade of traditional distribution networks with the concept of SmartGrids, a cost-effective connection of renewable sources to the network will not be possible. The presented Program defines the necessary research, demonstration projects and mass implementation projects that will enable the introduction of new SmartGird technologies into practice and their optimal utilization. The proposed projects will enable efficient transition to smart distribution networks. With better exploitation of existing infrastructure enabled by new technologies, the required investments can be reduced. According to the economic analysis in the Program, almost 500 million lower total investments are expected with the introduction of SmartGrid concepts, which is a reduction of 11 % when compared to existing network development plans.
