Optimization of energy procurement and load management

Programs for optimizing energy procurement are incorporated in the control center of the Pflazwerke AG. A main element in the optimizing strategy is load management. The authors deal with the procedures for energy import optimization based on the results of a load forecast program. Special emphasis is put on load management and the investigations for modeling the load behavior depending on season, kind of day, and temperature. In addition, practical aspects in exceptional situations such as equipment failures are handled. Load management is achieved by ripple control of storage heaters with an installed capacity of approximately 65% of the peak load
