Optimizing the Grid in Real Time

By combining Grid data, Asset information, Customer Consumption, Load Profiles, and real time SCADA measurements the ADMS calculation engine is able to calculation the energy flow in the entire grid in near real time.

Project Life Cycle – Extending and Maintaining the grid

GIS Project Assistant▪ Documents the plans for the project in GIS.▪ Creates patch exports for DMS.▪ Post changes in GIS when project is in production in

DMS.▪ Documents final implementation once information is

received from project manger.

Grid Operator▪ Controls the switching state of the network▪ Communicates with the field crew during commissioning or

decommissioning of equipment.▪ Energize patches in DMS which updates the electric model and

triggers feedback to GIS.

DMS Model Manager▪ Evaluates patches and approve them for later

energization or reject them and return them to GIS for corrections.

▪ Draws schematic layout in DMS.▪ Ensures that new data sent to DMS is correct.▪ Handles full feeders containing final

documentation of the network.

Project manager▪ Plans the work to be carried out▪ Delivers plans to GIS documentation

department▪ Delivers finial documentation when the job

is carried out.

Field Crew▪ Follows the orders of the grid operator.▪ Carries out the work planned by the project

manager.▪ Delivers information for final documentation

of the finished project to the project manager

SMS’s are send using service endpoints on SAP-PI and a 3rd party SMS Service Provider. SMS’s can either schedule or cancel an outage.

If we are unable to send a SMS, a letter are send using service endpoints on SAP-PI. Letters can either schedule or cancel an outage.

▪ Customer load with synthesized load curves.

▪ Load flow every 10. min with calculated loads and voltages for all components

▪ Short circuit for breakers and switches every 24 hours.

▪ Contingency (N-1) every 4 hours.

Smart Grid Ambition

Data Requirement

Smart Grid Ambition

Data Requirement

• Data Quality is relative to the usage. Working with Smart Grid

this fact becomes very evident

• The business case of the Smart Grid strongly depends on the

organization's ability to produce and maintain high quality data

• The real option for automating the grid requires accurate data

• The data model must capture a rich and precise electric

representation of the grid

• Completeness and classification correctness must be close to

100% (if not 100%)

• Data is shared among multiple systems for multiple purposes

Implementing the GIS-ADMS integration

41

▪ Form a Master Data Management Strategy

- Get an overview of what data is needed in which system and in which process

- Delegate the responsibility of storing each needed data element to a particular system

- Ensure that all data elements are maintained as close to the business process changing the configurations

▪ Work with business processes

- Understanding the actual processes

- Select the ones that will be supported

- Draw the primary data flows

▪ Enrich the data

- Identify the critical data for supporting processes in ADMS

- Validate the current state on these data: Completeness, accuracy, classification, topology?

- Plan the data cleansing processes, and how the data is validated in source and target systems

▪ Make a masterplan

- Establishing the needed organization

- Defining the key milestones

- Align Expectations

• Further integration of maintenance processes across technology platforms

• Extend the use of GIS to analyze, explorer and visualize data

• Streamline the current integration and dataflow

• Support new business process for asset management and “Smart” Maintenance

MAINTENANCE STRATEGIES

Condition-based maintenance (CBM):

CBM periodically evaluates the state of equipment deterioration expressed quantitatively as a score or failure risk, and maintains equipment when the condition falls below acceptable thresholds. Additionally, CBM approaches rank assets within a given asset group with respect to each other, thereby enabling a prioritization of investments.

Time-based maintenance (TBM):

TBM is performed at regular and scheduled intervals, loosely based on the service history of a component and/or the experience of service personnel. This maintenance policy can be expensive and may not minimize the annualized cost of equipment.

Reliability-centered maintenance (RCM):

RCM considers both the probability of equipment failure and the system impact should a failure occur. RCM approaches rely on frameworks for estimatingnetwork reliability indices based on the failure rates of the different components. Most commonly, suchframeworks operate at the level of individual feedersand can be divided into analytical and simulationapproaches.
