Integrated energy management in distributed systems

Energy management describes the process of managing the generation and the consumption of energy, generally to minimise demand and costs. The energy management has to look for efficient solutions for the challenges of the changing conditions of the international energy economy which are caused by the world wide liberalisation of the energy market restricted by limited resources and increasing prices. Before this background distributed energy resources become more and more important. The paper focuses on a multidisciplinary approach to the development of energy information systems combining mathematical and informational methods with energy generation and saving technologies related to the framework of the energy economy. Energy management methods are demonstrated by the analysis and forecast of the power consumption as well as by the optimisation of the operating schedule in cogeneration systems
