Abstractions for operator support in energy management systems

This paper describes operator support systems for energy management, based on two complementary approaches. The first one involves development of synoptic views of network status that present the system to the human operator in a concise way. The second involves development of software components that reduce the amount of run-time information directed to the operator. Both approaches implement abstracting mechanisms along the space and time dimensions of the supervised process. It is argued that the described techniques support effectively the operators in their complex task of supervision and management of power transmission networks.
