DR. GYURCSEK ISTVÁN Outlook - SmartGrid; SmartMetering What is SmartGrid and what is it for? What are the main advantages of the SmartGrid compared to the traditional (centralized) systems? What are main benefits of the SmartMetering (part of SmartGrid) for the providers and consumers? Outlook: Where do you want to go today? 1 gyurcsek.istvan@mik.pte.hu 2017.07.25.

Smart Grid Use Cases 1 USE CASE 1 too high produced energy Strong wind at night energy-surplus local consumption (by switching on the controlled loads) AC mode; Economic Comfort heat pump max. water heater on garage car battery charging USE CASE 2 Local excess voltage Summer, empty flat (low consumption) PV System (Photo Voltaic Sys) on max. PWR opposte flow of energy excess voltage! Prevention PV System (inverter); OFF (no product, of energy) Local Energy Mgmt Local Consumption; ON (swicth on local controlled loads). 3 gyurcsek.istvan@mik.pte.hu 2017.07.25.
Smart Grid Use Cases 2 USE CASE 3 Urban load peak at the evening Mgmt. borrows i.e. from i-car battery. US CASE 4 too low energy production Enegy management AC to economic Enegy management heat pump OFF Enegy management controlled loads (water heater, etc.) down-regulation or switch off Garage: e-car charging pause. USE CASE 5 transzformers-overload Evening overload of public transformers local area control (switch off) E-car avg. 10 hours in garage, avg. Charging time 5-7 hours charging control nighta/dawn (+tarrif incentives!) Comments to charging controll; charges only grounded car, ignition impossible, local, local area urban controll on charging even backfeed controll Source: The interaction between KNX and the intelligent power grid (smart grid), KNX Journal, 1/2013. 4 gyurcsek.istvan@mik.pte.hu 2017.07.25.
What is Smart Grid? HISTORY Idea of the traditional (AC) electric network is 120 year old (Nikola Tesla) 20th century large, connected networks centralized PWR stations, peak PWR stations hard to MTR consumption. 21th century claim for renewable sources, smart IT NETWORK REENGINEERING. (centralized system distributed system) First SmartGrid (2000) Italy; 27mn connected consumer. SMART GRID Distributed structure ICT technology based BigData acquisition (Consumer - Provider) Automatic efficiency control (Reliability Economy Sustainability) Smart Buildings (Remotely managed/controlled by SmartGrid!)
