WG-2 ObjectivesThe objectives of the group are summarized as: Develop the vision for the next generation of EMS/MMS

architecture Gain adoption of the vision by the industry Facilitate its implementation as a de facto industry standard

The work in 2005 focused on: Identifying and prioritizing EMS/MMS issues common to

VLPGOs, and developing an international consensus Diagnosing present architecture problems Developing a high level vision for EMS/MMS systems for 21st

Century Developing recommendations Developing an actionable plan for 2006

Common General Issues The working group members were able to identify a

number of common general issues with current EMS/MMS architectures:

Excessive dependence on limited number of viable EMS vendors

Inadequate protection against cyber attacks. Lack of standards, usually limited to low level

protocols. Limited innovation, due to absence of standard

requirements and small market size.

Systems with a high Total Cost of Ownership

And similarly there was common agreement on key technical weaknesses

Lack of modularity and interoperability are obstacles to multi-vendor integration.

Inconsistent implementation of standard data models impacts interoperability.

System Design, driven by real-time performance requirements, prevents ease of expansion and reusability of software components

Multiplicity of User Interfaces among EMS/MMS functions and other control room systems limits operator effectiveness and increases error probability.

Systems that are difficult to operate and maintain

Common Technical Issues

Identified Root Causes Root causes for the identified problems can be traced to both

Vendors and Utilities

Vendor products have evolved over timeo High levels of investment required to make radical changes to

architecture. Limited market size

o Constrains investment potential. Lack of standardization in industry requirements

o Divergence in business requirements o Lack of coordination between system operatorso High levels of customization

High system performance requirements

The business model needs to change

Future StateDriving Principles

Any future state must support the following driving principles

Component Reusability

Platform Independence

Security built in

Business Continuity

Standards based

Performance

3rd Party Integration

“Evergreen”

Future StateIT Reference Architecture

The driving principles translate into the key requirements for an IT Reference Architecture:

Component based, Services Oriented Architecture for integration and reusability

Common Information Model and Market Extensions for data standards

Collaborative Business Models

There is an opportunity for the International Working Group to leverage and expand on a limited number of initiatives, such as:

International technical cooperation agreements Inter-regional coordination Joint funding opportunities

Recommendations Communicate the vision and rally industry support Refine the vision and develop common requirements

for the future EMS/MMS architecture Perform Gap Analysis and identify highest priorities Communicate development priorities to R&D

organizations and coordinate initiatives (e.g. EPRI, Gridwise, EPRI China, Hsinghua University, ECC)

Identify and plan opportunities for joint development/funding

2006 Action Plan Communicate the vision and rally industry support

o Joint meeting with IWG #3 – 1Q06o Presentations at key conferences (e.g. Cigre, IEEE Summer

Conference)– 2Q06o Publish joint white paper – 4Q06

Refine the vision and develop common requirements for the future EMS/MMS architectureo Develop an initial set of common requirements – 2Q06o Establish Workshops with vendors and consultants to gain industry

consensus and drive convergence – 2Q06o Finalize common requirements to be included in future Requests For

Proposals – 4Q06 Perform Gap Analysis and identify highest priorities

o IWG #2 Workshop – 3Q06 Communicate development priorities to R&D organizations and

coordinate initiatives (e.g. EPRI, Gridwise, EPRI China, Hsinghua University, ECC, CEPEL)o Regional Workshops with R&D organizations – 3Q06/4Q06

Identify and plan opportunities for joint development/fundingo IWG #2 Workshop – 3Q06/4Q06
