Sep 04, 2009 | At Solnova 1, mirrors in the form of parabolic troughs concentrate sunlight in a pipe and heat up special oil, the so-called heat transfer medium, circulating in it. Another method consists of concentrating sunlight from numerous flat mirrors on a small surface at the top of a tower frequently over 100 meters in height. A range of different technologies will likely be used on the visionary Desertec project: the project plans to transfer electricity from solarthermal power stations in Northern Africa to Europe. Over such a distance, this is only possible with little leakage using high-voltage DC transmission systems (HVDC). HVDC lines will constitute the backbone of future interconnected networks as “electricity highways”.

Sep 04, 2009 | In the future, car drivers will be able to precisely preselect how much electricity the battery should store and when it should be charged. The car will thus become a flexible electricity trader in the Smart Grid. Cars could fill up at night in the future, when electricity costs less, and feed energy back into the network during the day, when a particularly large amount of electricity is required. It is by all means conceivable that the car owner will be remunerated for this electricity. He could individually select charging and feed-in times, drawing electricity when it is cheap and feeding in when he receives the most money for it. In any case, the car driver can determine for himself in detail the charging status of his vehicle – for the daily commute to work or the start of his annual vacation.

Sep 04, 2009 | Siemens, in association with the high-performance carmaker Ruf Automobile GmbH, has demonstrated how attractive electric vehicle can be with the eRuf Greenster. The eRuf Greenster is already fitted with charging technology to charge up at public electric vehicle filling stations. It is therefore already today part of the future Smart Grid.

Sep 04, 2009 | Researchers at Siemens Corporate Technology have developed an integrated system of engine/generator, power electronics, and an interface with battery application for the eRuf Greenster prototype from Ruf Automobile GmbH. Siemens’ central research unit is conducting an exhaustive investigation into electric mobility, including the requirements for the electric car with the electric drive and recovery of energy, as well as the configuration of the infrastructure.

Sep 04, 2009 | In future Smart Grids, electricity will no longer be centrally generated in large power stations but increasingly in small, local units. Even residential buildings will become producers of electricity. Photovoltaic modules on the roof or facade will directly supply electricity which is then fed into the network. In addition, intelligent building technology will ensure a reduction in building power consumption, for example with more needs-based air conditioning and ventilation technology.

Sep 04, 2009 | A house today, together with its appliances such as a heating pump, refrigerator or consumer electronics, is usually an electricity consumer. However, a Smart Grid will make it possible to reverse the flow of current. Photovoltaic systems are today already feeding electricity into the supply network. In the future, the car may also become an power supplier. The idea: when a large amount of electricity is available, the car battery charges up. If power consumption increases, for example in the early evening, the flow is reversed. The car feeds electricity into the network. In the future, when millions of electric cars are connected to the supply network, they will even be able to buffer the fluctuating supply of solar and wind power. In place of building storage systems to cushion current fluctuations, cars and their batteries will automatically provide storage capacity.

Sep 04, 2009 | In the future, electric cars will be equipped with a quick charging function, enabling them to charge up within a short time. Cars could then be recharged within a few minutes at charging stations, similarly to current filling stations. Integrated charging technology systems for vehicles are currently under development. These systems operate with considerably higher voltage and amperage to quickly replenish the batteries. In addition, the technology will be fitted with a communications interface with which the vehicle can exchange data with the power supplier. In a similar way to the cellular phone, the vehicle will be identified and the amount of electricity accordingly invoiced.

Sep 04, 2009 | A car spends the majority of its lifetime parked. An electric vehicle can therefore be easily charged in the parking garage while its owner is shopping or at work. If several hundred vehicles draw electricity from the supply network simultaneously, large amounts of electricity are quickly accumulated which can be networked via substations. Siemens has had this kind of network technology in its portfolio for a long time. It is currently being adapted for use in the Smart Grid. Parked vehicles can of course also be used as electricity suppliers. In the future, when millions of electric cars are connected to the supply network, they will even be able to buffer the fluctuating supply of solar and wind power. Smart Grids, and with them electric cars, will thus counteract power failures – even in the event of heavily fluctuating power generation.

Sep 04, 2009 | Following successful final acceptance testing at the Nuremberg transformer plant, the 800 kilovolt extra-high voltage convertor transformer is ready for delivery. The transformer will be used in the “Yunnan-Guangdong” high-voltage DC transmission system (HVDC) in China, one of the current two HVDC systems with the highest rated capacity in the world.

Sep 04, 2009 | The share of offshore wind farms supplying European energy is increasing. In strong winds, Denmark could today generate more electricity with existing wind turbine generators than the country consumes. However, the fluctuations in the generators, a result of the weather, make more intelligent networks necessary for further expansion of capacity. One day, these might, for example, automatically switch over in good time to other generators during periods of calm weather without becoming unstable. In the pictured Lillgrund offshore wind farm in the Öresund between Malmö and Copenhagen, 48 Siemens SWT-2.3-93 wind turbine generators with an output of 2.3 megawatts each have been installed.

Sep 04, 2009 | Ever more solarthermal power stations are connecting to the grid in Southern Europe. They concentrate sunlight with the help of mirrors and use it to heat water. Under high pressure, the steam then drives a turbine. The technology has already existed for decades but only now reached a degree of efficiency to make its large-scale use attractive. Subsidies are providing a further boost. While the pictured Solnova 1 plant at Abengoa Solar, near Seville, has a capacity of 50 megawatts, numerous projects at the development and construction stage are already providing for a power station capacity of far greater than 200 megawatts each. Siemens has the technology for the key components of solarthermal power stations in its portfolio.

Sep 04, 2009 | Siemens is today the global market leader in control technology – an essential pillar of the Smart Grid – and has deep experience from initial Smart Grid projects in the U.S. and Europe, for example in the connection of wind farms and other renewable energy sources. Electric mobility will evolve into an essential part of the future Smart Grid. Siemens already has the necessary technology in its portfolio.
