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...
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...
A smart start program decision making system based on power system integrated data platform is introduced in this paper. The data platform of the power system is integrated with EMS, GIS, DAS as well as MIS for protective relaying, which abbeys IEC61970. Many obstacles are conquered with all of the new techniques, which will be described in detail.
This paper describes the implementation, testing, and performance of phasor measurements in an industrial state estimation at the New York Power Authority (NYPA). Phasor Measurement Units (PMU) with GPS synchronization were incorporated into the data acquisition subsystem of the Energy Management System (EMS). The modified state estimator was subjected to pre- and post-field installation testing....
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...
The real-time voltage stability analysis (RTVSA) project is slated to be a part of the suite of computational tools needed for congestion management in the California ISO (CAISO). This is because the problems of voltage stability will be magnified by the effects of multi-transfers through the network. These simultaneous transfers are manifest due to the buying and selling of electric power when the...
This paper presents a cost effective approach, using special-purpose hardware implemented using field programmable gate arrays (FPGA) - commodity programmable hardware, to accelerate the performance of key components of an energy management system (EMS). These components include state estimation, optimal power flow, and load flow computation. All of these components have at their core the solution...
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.
In order for electric power generating capacity to be supplanted to a meaningful extent by sources smaller than 200 kW, an automated means of managing systems of small sources must be found or their sheer number will over-whelm the power production community. Micro grids - power systems comprising multiple small interconnected generators - are a promising response to this need, but an automated micro...
The IEC TC 57 common information model (CIM) started with a focus on the power system models in the energy management systems (EMS) domain. The need for a common model in distribution management systems (DMS) and market operations drove CIM into those areas. The CIM was created in order to provide an information exchange format to facilitate the integration of applications and systems independent...
Control centers (CC) play a very important role in power system operation. An overall view of the system with information about all existing resources and needs is implemented through SCADA (Supervisory control and data acquisition system) and an EMS (energy management system). As advanced technologies have made their way into the utility environment, the operators are flooded with huge amount of...
