Knowledge management based cooperation for energy cost optimization

Abstract

The paper presents studies on the improvement and development of cooperation methods for cost optimization in power supply systems using polygeneration technology. A support for cooperating operators, which are responsible for maintenance and supervision of the power supply system, is realized by means of appropriately chosen mathematical models and ontology based knowledge sharing and management idea. Ontology based approach enables various pieces of the integrated system to cooperate more autonomously by optimizing and reducing their need for communication. In effect, the system operators are provided with strictly necessary information on: the functioning of devices, the number of operating states, available control strategies and the actual and expected prices of electricity. Based on this information, the system operators are able to take appropriate decisions leading to cost reduction and to maintain reliability of the power supply system at the desired level for various operating conditions. © 2013 Springer-Verlag Berlin Heidelberg.
