DMS Guides on Switch Order Management Project


Distribution Management System Guides(P180.012)

• Overall research objectiveExpand electric distribution industry knowledge of Distribution Management System (DMS).

• What are we doing in 2016?Developing guides to provide specific, proven and practical guidance for deploying and operating Switch Order Management.

• Why is it valuable?Members participating in this research can apply the Switch Order Management (SOM) Guide to support the creation, execution, display, modification, maintenance, and printing of switching orders and benefit by being able to take advantage of the experiences of multiple utilities, avoiding pitfalls and accelerating achievement of benefits.

Operational Research


Operational Studies and Research(P180.013)• Overall research objective

This research will investigate and expose the impacts of the changing distribution utility landscape on Distribution Operations. This new project, initiating in 2016, will encompass a wide range of studies and research to determine the most effective approaches to a number of operational decisions.

• What are we doing in 2015?The challenges and opportunities associated with adaptive feeder protection (e.g. fuse saving, reclosing, etc.) will be studied and evaluated.

• Why is it valuable?Existing decisions may be based on historical norms for a particular utility, regulatory requirements or pressures, local customer expectations or some other combination of factors. This research will expose the key contributing factors that lead to different approaches, enabling utilities to evaluate the benefits of changing from their existing operational practices.

During normal blue sky days, do you mostly employ FUSE SAVING or FUSE SACRIFICE on your distribution feeders?



Yes3

No19

Do you adaptively switch from FUSE SAVING to FUSE SACRIFICE based on operating conditions

(temperature, weather conditions, etc.)?



How many shots of reclosing do you typically set on overhead distribution feeders?

Next Steps

Instead of looking at data that was previously collected, we need to collect fresh data for the next year.Each Utility picks 4 feeders

– Treed– Significant Fault History

For the next 12 months collect detailed fault information for these feeders (Oct 1 2016 – Sept 30 2017)– Breaker / Recloser Operations– Digital Fault Record Including Maximum Fault Current– Concurrent Fuse Outages– Mainline Patrol Results (if part of normal processes)

EPRI will analyze these records looking for correlations with wind/lightning, fault current, etc.


DA/FLISR Application with DER Project


Smart Distribution Applications for Distributed Energy Resources (P180.014)

• Overall research objectiveDetermine expanded role of DERs in volt-VAR optimization, reliability improvement measures, system reconfiguration, microgrid operation and control, and other DA/DMS applications

• What are we doing in 2016?In 2016, this work will continue with deep dives into the specific changes necessary to deploy an automated restoration (fault location isolation and service restoration, FLISR) application, as well as the changes necessary to deploy predictive fault location on distribution systems with high penetration of DERs.

• Why is it valuable?Provides insight into new functions and operational benefits from integration of DERs.

2016 Project: DA/FLISR with DER

THE PROBLEMAutomated Restoration (FLISR, FDIR, FISR, etc.) solutions

lack visibility and control of DER assets

IMPACTRestoration Control algorithms do not account for total load

(resulting from the loss of DER after initial trip)Existing algorithms will fail in several different ways:

– Restore then trip on overcurrent– Restore then an asset (wire) will fail on overload– Fail to Restore


Example of the Problem – DA/FLISR with DER

0 MVA0 MVA

12.6 MVA 9.5 MVA 6.3 MVA

The FLISR Algorithm is only aware of 9.4 MVA, however with the loss of all DER supply, the actual Load to be Restored is 12.6 MVA.

Normally Open DA Switches F and L are closed to restore service. This is OK for Feeder 1, but the feeder supplying Tie L will get 2.3 MVA more than it expects. This could lead to an Overload or a Trip.

Things to Investigate and Model with New FLISR AlgorithmMonitoring of DER to be able to monitor and react to TOTAL

LOAD, not just NET LOAD (Total Load – DER Contribution)

Simulate the ability to Control DER from FLISR commands to restore the DER Contribution within the FLISR restoration cycle

Model different control algorithms to determine which switching steps to use for FLISR based on presence of and contribution of DER

Integration FLISR with Volt/VAR/CVR controls
