This paper presents the design and implementation of one object-oriented EMS real-time database. The database is constructed by the dynamic modeling technology based on the meta-data and meta-rules, conforms to IEC61970 standard. Compare to the relational and hierarchical database, the object-oriented database has the better openness and interoperability. The dynamic modeling technology based on the...
This paper describes a laboratory setup as the scaled model of a three substation power system. The scaled model has been developed at the Power System Control and Automation Laboratory of Georgia Institute of Technology. Elaborate physical models for the power system components along with high fidelity models for signal generation and interfacing to the laboratory setup are among its unique features...
In order to make the platform more effective, reliable and flexible, multi-agent technology has been used to construct a distributed computing platform for New generation of EMS (N-EMS) in this paper. Staged Event Driven Architecture (SEDA) model and cluster-computing technology are proposed to implement the agents for a single function, and then taking Blackboard model as a media, these agents are...
Energy Management Systems (EMS) play the all important role of monitoring and control of the power systems and state estimation forms its backbone. In these days of increased operation of power system near to its limits and the tendency to utilize the grid to its full potential, monitoring and control with high level of accuracy becomes a boon. Dynamic state estimation (DSE) techniques with their...
A major step in the evolution of Energy Management System (EMS) capabilities is towards improved presentation of real-time power system condition information (not just data) to the system operator; the primary purpose being to facilitate prompt identification and location of problem areas, and to expedite confident decision-making, in order to mitigate or obviate escalation of the problem at hand.
With the development of electric power market, the centralized legacy energy management system (EMS) is hardly adaptive to the polytrope of market environment. Firstly the definitions of agent as well as multi-agent system (MAS) are analyzed. Then based on the knowledge of ontology and considered IEC 61970 common information model (CIM) as the data ontology of EMS region, the structure of ontology...
