In this paper we use concepts from a philosophical ontology to guide us in interpreting the concept of role. Specifically we chose two(More)
This paper deals with load frequency control of an interconnected reheat thermal system considering battery energy storage (BES) system. Area control error (ACE) is used for the control of power system with battery energy storage system. The controllers design problem is formulated as an optimization problem. The genetic algorithm (GA) is used to search for(More)
