The project’s main technical aim is to collect real-world experience with innovative battery and other energy storage Grid integration of Pellworm island’s energy storage solutions and observe the portfolio. effect of energy storage on the grid’s operation. Pellworm Island smart grid - operational strategies The operational strategies for the Pellworm smart grid will comprise market, grid and local supply-oriented storage and RES (Renewable Energy Sources) operation including the direct marketing of renewables, a joint operation of fluctuating renewables and storage systems to address different markets for RES and VPP (Virtual Power Plant) operators, a day-ahead and intraday market, and finally reserve power markets. For the DSO (Distribution Service Operator), the primary goal of the project is the grid integration of renewables to support the distribution grid operation. This will enable the service operator to prevent power curtailment, support voltage and reduce losses. For power companies, Renewable Energy Sources (RES) and Virtual Power Plant (VPP) operators, the project should support the direct supply of local customers with energy from regional renewable generation units while storage systems could be operated to balance generation and local demand. This yields a combination of direct regional supply and market transactions which are also grid compatible with the aim of reducing curtailment. Energy storage - making smart grids smarter Dr. Klaus Peter Röttgen, Head of Energy Storage at E.ON’s Innovation Center, explains why E.ON believes that energy storage will play a vital role in smart grids: “E.ON regards energy storage as a key innovation that will help improve the grid performance and especially the integration of renewable energy, and Li-ion batteries are one of the most interesting and important technologies in this sector. Pellworm Island is therefore a crucial lighthouse project that will enable us to evaluate how Li-ion technology can operate in a real-world situation to help make smart grids even smarter.” “Further detailed analysis will be required to determine how much energy storage capacity is required, but the initial suggestions are that for Europe it will be in the order of Gigawatts. The horizon for implementation at this scale is very closely tied to the penetration of renewables, since the more renewables that are connected onto the grid then the greater the need for storage to address the volatility and grid compatibility issues. ”For E.ON, the most important barriers to the introduction of energy storage are not technical, so much as legal and administrative. Key questions need to be answered such Saft Intensium Max containerized Li-ion energy storage system. as: how will energy storage systems be financed? How will the services they provide be paid for? How can we provide potential investors with the security they need in planning their investments?” Overall, the prospects for energy storage being accepted are good, especially with compact solutions such as Li-ion technology that are easy to install within a restricted footprint. The main measures for the success of this particular project will be that the system works as promised, that there are no HSE (Health, Safety and Environmental) concerns and that the costs are acceptable for future commercial installations. But it is equally important that politicians and the general public they serve are happy with this solution. www.electronics-eetimes.com Electronic Engineering Times Europe September 2013 41
