Just a reminder for those planning to attend the 22nd annual EMMOS (Energy Management and Market Operations Systems) user group conference on September 21-23 at the Marriott Renaissance Hotel in Carmel, Indiana can make hotel reservations at a discounted rate until August 27th.
This year’s conference agenda will feature topical speakers and roundtable sessions, technical training classes and a vendor exhibition.
Featured conference and training topics at the 2015 gathering of North American and international control and market systems operations management and staff include:
- Cyber Security Perspectives in Light of CIPS V5
- Overview of MISO Market and System Reliability Operations
- North American Developments in DMS and DA Usage
- Situational Awareness
- Communications Standards
- Renewables Integration and Management
- Network Security Applications
- Next Generation Systems
- The Future of Energy – Smart Grid and Beyond, and several additional control systems related topics.
The 2015 conference will include tours of the Midwest ISO (MISO) control center on Tuesday afternoon and Wednesday morning. The vendor exhibition will include a cocktail and hors d’oeuvres reception on Monday evening.
The annual EMMOS conference attendees include electric power operations officials involved with transmission, distribution and generation, as well as IT managers, planning engineers, consultants, ISO staffs, and related systems personnel involved with control systems and substation modernization, distribution automation, outage management and geographic information systems.
Further information on the upcoming 2015 EMMOS conference, including registration information and hotel booking arrangements can be found on the EMMOS website at www.emmos.org. Exhibitor opportunity information is available from Ms. Erika Ferguson at EFerguson@osisoft.com
This is part one of a four part series on ADMS and Distribution Automation. Part one discusses Advanced DA, differences between Distribution SCADA and ADMS, market participants, usage patterns, challenges, priorities, and comments from users.
What utilities have said
Based on a mid-2014 study of the market for Distribution Automation (along with multiple earlier studies), increasing numbers of large utilities have indicated the following:
- Integrated systems are becoming more desirable
- Entrenched suppliers of large control systems (EMS primarily) have an “in” but often cannot provide the required component systems for an integrated approach to DMS-OMS-GIS.
- Many mid-size utilities consider their DSCADA systems (primarily the ACS, OSI and Telvent communities) as suitable platforms for DMS/DA.
- A high proportion of all respondents do not yet see a need for a separate DMS. This is especially true among the mid-tier utilities.
- DMS systems can be (and most often are) implemented in a single control center that cuts across state lines in the United States.
- Typically, operating companies under a large holding corporation operate their own DMS or DSCADA installations.
10 attributes of advanced DA
Here are the 10 attributes of an advanced distribution automation capability based on Intelligrid’s definition:
- Real-time Distribution Operation Model and Analysis (DOMA)
- Fault Location, Isolation and Service Restoration (FLISR/FDIR)
- Voltage/var Control (VVC/VVO)
- Distribution Contingency Analysis (DCA)
- Multi-level Feeder Reconfiguration (MFR)
- Relay Protection Re-coordination (RPRC)
- Pre-arming of Remedial Action Schemes (PRAS)
- Coordination of Emergency Actions (CEmA)
- Coordination of Restorative Actions (CRA)
- Intelligent Alarm Processing (IAP)
While ADMS platforms are increasingly used by Tier One utilities, many other utilities continue to rely on their DSCADA system to manage a growing portfolio of ADA functions.
Use of DMS as of Mid-2014 (Participants in Newton-Evans’ Study)
- Just over 40% of all respondents indicated use of a DMS as of June 2014.
- IOUs were more likely to indicate having a DMS installation than were respondents from other utility types.
- All of the surveyed utilities have a DSCADA capability and are likely to be applying SCADA control over basic DA functions such as capacitor bank control and recloser control.
ADMS and DSCADA market participants
The total North American DMS market is made up of ADMS and DSCADA, with some overlapping providers and some different market participants in each category. Among this North America sample of large utilities, GE and ABB/Ventyx led in mentions of current ADMS installations. OSI is also a major supplier of DSCADA and ADMS installations, but their clients tend to be mid-size utilities. All of the mentions for both GE and ABB/Ventyx were made by IOU respondents.
