This paper presents the experiences in enhancement of Energy Management System (EMS) real time model, development and implementation of an application, and methodologies to validate the EMS model at Vermont Electric Power Company (VELCO), a ‘transmission only’ company in Vermont and a Local Control Center (LCC) for Independent System Operator in New England (ISO-NE). Methodology is developed for comprehensive...
This paper presents the experiences in enhancement of Energy Management System (EMS) real time model, development and implementation of an application and methodologies to validate the EMS model at Vermont Electric Power Company (VELCO), a ‘transmission only’ company in Vermont and a Local Control Center (LCC) for Independent System Operator in New England (ISO-NE).
This paper outlines the reasons why COES wants to adopt the CIM standard and the road map to make its information systems compatible with CIM. COES information system is an internally developed system (SICOES), and would be the starting point to adopt CIM. It is necessary to integrate the data of the third party software used in COES for power system analysis activities to the SICOES central equipment...
In our approach, we model an ICT-architecture for the utility domain for both transmission and distribution grids according to the IEC standards 61968 and 61970. To achieve this, we use three basic components. The first component is the Common Information Model (CIM) which is standardized by the IEC 61970/61968 standards. The OPC UA (Unified Architecture) is the second basic component. The OPC UA...
NSTAR is an investor owned utility transmitting and delivering electricity and gas to customers in Eastern and Central Massachusetts. In the process of becoming a Local Control Center, which allows NSTAR to work more closely with the Independent System Operator - New England (ISO-NE), NSTAR upgraded its SCADA system and added an integrated Energy Management System (EMS) in 2007. In anticipation of...
Energy management systems (EMSs) suffer from poor external modeling during wide area event occurring in interconnected power systems. In order to improve this situation, an IEC61970 standard based hierarchical network remodeling system for electrical power control centers is designed in China. In this designed system, through a wide-area communication network, each underlying control center automatically...
Powerlink Queensland is currently in the advanced stage of implementing a CIM-based enterprise-wide network asset model maintenance system. This model allows a single common repository for the planned and operational network model for use by planning, operations, EMS and protection. Planners are able to enter future projects with multiple possible scenarios with the capability to move the projects...
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...
