ELEKTRO MARIBOR AND SMART CITY
KOMUNALNA ENERGETIKA / POWER ENGINERING, 22
Globalization and economic and technological changes put before us the task of how to simultaneously ensure competitiveness and sustainable urban development. Quality of life in the city is dependent on the residential, commercial, cultural, social and environmental conditions, as well as it depends of all of the services that the city provides to its residents. Group Elektro Maribor strives to integrate approach of providing the building blocks of the different areas of Smart City.
The construction of advanced metering system, which is next to information and communication technologies, one of the basic building blocks of Smart grids, energy consulting and energy consumption displays is in the quality of live area. In the future the main topic will be implementation of adaptation measures consumption and power management. Advanced technologies are an excellent bas for mutual cooperation areas dealing with different energy sources (water, gas, electricity). On the other hand, the advanced services are based on the use of new, more efficient ways to communicate with customers.
Area of Smart Economy refers to the Smart Grids, mobile payment and dematerialisation of documents. In the environmental field there are, next to the previously mentioned smart metering, smart buildings and smart lighting. eMobility, which can have a significant impact on reducing CO2 emissions and PM10 and PM2,5, contributes significantly to the Smart Mobility, Smart grids can, at least partially, solve problem in the operation of the distribution network that are due to the rising share of distributed generation units that are connected to the electricity grid.
Integration of building blocks, which is a new option and opportunity, will be possible with the active participation of conscious local communities.

»SMARTGRIDS IMPLEMENTATION IN THE CASE OF ELEKTRO MARIBOR«
KOMUNALNA ENERGETIKA / POWER ENGINERING, 5
Limited sources of fossil fuels and emissions of greenhouse gases related with the combustion of these fuels force use to increase the use of renewable energy sources. Unfortunately, the renewable energy sources are often distributed in the space and are not always available. Technical solutions for utilization of renewable energy sources are relatively expensive while the cost of energy, produced in this way, are too high to be economically bearable without national support schemes.
In spite of aforementioned drawbacks, European Union and Slovenia have made political decisions to support energy production from renewable energy sources. The electrical power generation based on renewable energy sources in Slovenia is focused on utilization of sun energy, water energy and biomass. A substantial increase in the number of installed electric power generation units, based on renewable energy sources, has been reported the last years. The share of photovoltaic power plants is dominant. It must be pointed out that the power system, as well as the transmission and distribution networks, were designed and build considering the energy flow from the power plants towards consumers. However, the increasing share of distributed electrical power generation units, connected to the electricity network, can change the direction and increase the dynamics of changes in the power flow. Such operation could cause problems in the electricity networks not designed for that kind of operation. The solution called SmartGrids should help to solve problems, related with the increased share of distributed power generation connected to the electricity networks.
