Intelligent networks and energy management
The electricity generated from renewable energies and fed in from a multitude of decentral plants is subject to substantial fluctuation depending on weather conditions. New, intelligent grid concepts will help to coordinate electricity generation and electricity consumption more flexibly with each other. New line technologies will help minimise transmission losses during power transmission. One example is the ‘Smart Country’ project which uses real-time data to optimise the interaction between the generation of renewable energies and local consumption. Many of the technologies necessary in future are being developed today (Innovations).
Intelligent energy management
The project ‘PowerMatching City II’ in the Dutch village of Hoogkerk/Groningen has been testing the interaction between households, flexible micro-district heating power stations and electric vehicles since September 2011. This smart grid solution links up local energy generation, con-sumption and temporary storage. 25 households are participating in the project which will pro-vide the initial experiences and conclusions for nationwide application. PowerMatching City II was given an award in June 2012 by Sustainia, an initiative of the UN Global Compact, as an outstanding solution in the area of sustainability. RWE has been using ‘smart operators’ to test the interaction of decentral energy generation and supply-controlled ‘intelligent’ demand over the past two years. 250 test households in two local communities are taking part in the project (Innovations).
Electricity transmission lines from the next generation
In order to be able to operate existing grids more effectively, we are currently installing high-temperature transmission lines on a trial basis. They permit transmission of higher electricity loads and are therefore ideal for increased decentral energy generation (Innovations).
In future, underground high-temperature superconductors may be used in urban environments – despite a similar name, this technology is fundamentally different – to contribute to energy efficiency. We are currently running a pilot project to test this technology in the AmpaCity project (Innovations).
