Examples of Member Application of ResultsValue ObtainedUtility

R&D Applied

LES discovered what appeared to be delaminated low voltage cables in their underground network and wanted to know if they should expect similar conditions on other cables of that vintage or if external factors specific to that location were the cause.  EPRI performed material analysis on the cable samples, as well as reviewed historical information about the cables provided by LES. Results showed the cable vintage was not an issue and that the damage was caused during installation.

EPRI performed full-scale overhead distribution structure testing to determine the failure modes of an existing and a proposed resilient structure design when subjected to a tree strike. This testing required EPRI’s unique full-scale structure test facility located in Lenox, MA.

Alabama Power uses a single control type for all reclosers deployed on their system. This has led to the use of third party control cables that may not be as reliable for measuring voltages. Alabama Power provided details on the issue and equipment to perform testing. EPRI developed testing to understand the performance of recloser’s embedded sensors.

Distribution Automation is a key aspect of Entergy’s Grid Modernization investments. A successful wide-scale deployment of DA requires critical design and operations decisions. Entergy has a significant need to innovate, evaluate, and demonstrate solutions to meet this challenge and optimize benefits. EPRI has gathered industry knowledge of practices for the commissioning and maintenance of DA devices and the present state of DA. EPRI’s laboratory testing of self-powered reclosers provided information to inform standards development related to device specification, control algorithms, and benefits analysis.

The research results showed that LES should not expect cables of a similar vintage to experience delamination and that wholesale replacement of cables of this vintage is not warranted.

Testing demonstrated that the primary failure mode of the existing structure is a broken pole. The failure mode of the proposed resilient structure is a crossarm. By shifting the damage from the pole to the crossarm, Dominion will improve restoration time and decrease restoration cost.

Testing helps to inform Alabama Power’s decision of which control cables they should be using. The testing also provides an understanding of recloser sensor / control cable / control system accuracy for voltage and currentmeasurements which they would like to eventually send to their DMS to improve online power flow analysis.

EPRI’s testing results and industry knowledge has assisted Entergy in making informed decisions regarding the specification and application of Distribution Automation on their system.

Alliant Energy was able to more effectively focus internal resources towards assessing improvements and identifying forecasting needs to help evolve our forecasting practices.

At LG&E/KU we are in the middle of a multi-year DA project as well as adopting a new DMS/DSCADA system. Participation in this project is helping us to implement more effective alarming practices that will improve operator awareness and decision making.  I have learned many methods to help improve Alarm Management in the Distribution Control Center.  The timing of this project couldn’t be better.

This project was extremely valuable to Centerpoint by evaluating reverse power trip as low-cost alternative to direct transfer trip for DER with low annual running hours. This project proved to be successful in helping meet both Centerpoint and the customer’s needs by providing a safe and reliable solution while also saving valuable time and money.

Provided a fast, efficient method to assess our system to identify cost-effective solutions to mitigate DER impacts and increase hosting capacity. Without it, this analysis would have required manual techniques that take up valuable engineering time.

DRIVE was applied for interconnection application screening and has helped fast track dozens of applications. It helped reduce interconnection application processing time by ~10x.

P174 – Integration of Distributed Energy Resources

2019 HighlightsIn 2019, P174 had a continued focus on delivering value through ground-breaking research to help the utility industry address the technical and economic challenges of integrating distributed solar, battery storage, and other distributed energy resources. The following are highlights from 2019:New research area for DERMS and Microgrid Integration

(174C) – in response to industry need, this new project set was launched to focus research on developing requirements and conducting laboratory testing and field demonstrations to identify the benefits of the technology.

Determining settings for Smart Inverters – With the release of IEEE 1547, the DER Integration program is performing modeling studies and device testing to provide utilities with guidance on best DER settings for their needs.

Simplifying access to information – P174 facilitates a set of interest groups and online information resources to help program members find the information you need.

• Established DERMS, DER Field Experience, and DER Inverter Settings Interest Groups.

• Created an online repository of information on: utility interconnection practices RFPs and reference language for DERMS; and data analytic algorithms.

• Established the DER Forum – a searchable online discussion board where utility personnel can have direct dialogue with one another and with EPRI staff.

• Created an online research results finder that allows users to perform advanced searches for EPRI resources related to DER integration.

Demonstration Projects – EPRI brings a unique skill set to the table to help members with experimental design, monitoring and data collection, and analytics to create and manage objective, scientifically-based technology demonstration projects. The end result is hands-on experience and actionable insights to inform member decisions. Example projects include:

• Tucson Electric Power’s first of kind DERMs demonstration bringing together PV, storage, and flexible loads through open standards-based communication.

• Pacificorp’s in-depth look at utility strategy for smart inverters, including evaluating hosting capacity benefits, settings, and interconnection requirements.

• Salt River Project’s investigation of advanced inverter applications for voltage management in collaboration with central control systems.

R&D Applied

In collaborating with EPRI via their Smart Inverters and Grid Supportive Technologies program, Southern Company has gained a better understanding about real-world capabilities of today’s commercial inverters.  Demonstrating inverters from different manufacturers has informed how Southern Company continues to approach interconnecting distributed energy resources.

With the rapid advances in DER technology and accelerating DER adoption, EPRI’s TSO/DSO Coordination Working Group is addressing an urgent need of the power industry by taking up, in a systematic and detailed manner, all the practical issues involved with DER participation in wholesale markets and the operational needs of DSOs to support a high-DER future grid. While the industry abounds with TSO/DSO discussions at the conceptual level, EPRI’s diverse working group is figuring out how to make it all work. I look forward to reconvening in 2020 to continue the effort.

EPRI performed a comprehensive analysis of scenario-driven approaches for mitigating distribution system grid impacts using distributed energy storage. EPRI’s application of its cost benefit analysis method informed Entergy’s understanding of the economic value provided by distributed energy storage on a specific distribution circuit, evaluating capacity deferral value along with potential revenues from wholesale market participation. 

EPRI’s DERMS interest group has been very productive in exemplifying the challenges and considerations when selecting and attempting to implement a DERMS. Everything from covering current efforts EPRI has championed with utilities in prototyping towards a DERMS solution and the open discussion has shed light on the operational challenges and internal alignment needed for a large-scale implementation. The DERMS tutorial conducted by EPRI was very informative and helped APS internally align with the concept that a DERMS solution need not be exclusively a centrally-controlled system but may also be effectively employed as a federated system.

Leveraging industry knowledge and learnings accrued from standards development activities, EPRI reviewed Duke Energy’s Fast Track interconnection technical review practices and suggested improvements that recognize emerging inverter grid support functions, streamline processes, and maintain grid reliability and safety objectives. The assessment drew from national data and benchmarking with other utilities, and helped inform the technical review practices Duke Energy currently uses to review DER interconnection applications.
