Abstract
Cost reduction is a constant problem for modern regional utilities. Due to the liberalization of the energy market new possibilities arise. Energy is ordered out of the 110 kV- network of a TSO. Costs for the use- of — system charges and costs for energy trading at the spot market on the European Energy Exchange (EEX) have to be minimized. Technical, economic and legal restrictions must be brought together to reach this aim. There is an approach on the MV- Level chosen to investigate the possibilities of a regional utility. To have a reasonable size of control-, state- and environmental variables the MV- network is simplified by a mathematically and technically equal model witch includes the same complexity of all relevant variables as well as all types of side conditions.
After the development of the formal model the mathematical description for three time horizons (‘intraday’, ‘day ahead’, ‘long term’) will be developed concerning different entrepreneurial targets relating to the different time horizons. This leads to a discrete- continuous optimal control problem.
For investigation of the applicability of different optimization methods the properties of the optimization models were researched and shown by an example regarding the time horizon ‘day ahead’.
