Abstract In this project a state-of-the-art generic framework using service-oriented architecture for automated power production distribution in a network of virtual power plants is designed. The balance in the electrical distribution system is very important. Production must always equal consuming. When a sudden unbalance in the system appears, the transmission system operator uses the regulating market. The producer is required to start production within 15 minutes. This amount of time is because many large producers need to warm up their machines before a production can begin. Using smaller production units from a framework, the startup time could be significantly reduced because smaller units use less time to start producing. Smaller producers often cannot afford to trade in Nord Pool because of the expenses of the balance responsible actor, but if many producers join a network as a virtual power plant expenses can be shared. A virtual power plant means that several power producers join a network and with one interface to the outside world making them to appear as one power plant. The type of producers in the network might be wind power plants, combined heat and power units or any other type of producers. One of the problems in the power market is that trading cannot be done in real time. Because the Nord Pool exchange has secured slots for one-hour slots a day ahead the power production is not optimized fully. Ideally a power plant would start up and shut down (assuming this would be a cost-free task) as the markets fluctuate and optimize its own production. The one hour slots in a future solution should ideally disappear in a manner that would make the exchange between the best producers as flexible as possible. Trading has so far been done manually by a judicial entity with this responsibility. Software can be used to implement automatic trading. This might eliminate human resources from the actual trading functionality and decrease human errors, but also optimize production. An example is a wind power plant where changing weather makes production difficult to plan. The wind might be blowing for 5 hours followed by 5 hours of calm wind. These production peaks could be sold in an automatic trading system. In this project producers will be able to join the framework and trade power automatically. The framework uses a server broker agent to optimize and balance the production with the purpose of making it as effective as possible. The actual decision making regarding production does however lie with the producers themselves. The project contains analysis of problems and case studies of several design solutions.
