Paper and poster sessions

Cyber security: Cyber security assessment to improve substation security

Presenter: Fabricio Beltram |  Time: TBD
Paper authors:
Peter Rietmann, Fabricio Beltram, Steve Kunsman

Because today’s industrial control systems are networked more than ever before, there are new risks that threaten control system availability and security. Whether it’s a malicious attack, Stuxnet1-like worm or an unintentional security breach, such as an employee opening an infected file, the potential impact of such an incident could lead to endangerment of public or employee safety, loss of production, violation of regulatory requirements, harm to the environment and equipment damage. Having a well-defined cyber security strategy can help mitigate the risk of employee or system error as well as aimed attacks. This presentation will focus on outlining and discussing essential cyber security measures and features in the field of substation automation. 

Condition-based autoreclosing in an IEC 61850 environment

Presenter: Dmitry Ishchenko  |  Time: TBD
Paper authors: Dmitry Ishchenko, Mirrasoul Mousavi, Harshavardhan Karandikar

Using IEC 61850 standardized semantic models for disturbance recording, autoreclosing and protection trip conditioning functions offers an advantage for creating interoperable distributed protection and control solution. Mapping the semantic model objects to fast GOOSE messages for status and control purpose satisfies strict functional and time performance requirements. The presentation will describe the IEC 61850 architecture, services and data objects for the proposed solution and will provide several practical examples based on the real fault data.

What happened to the IEEE PES PSRC and how it effects the protection and control standards process

Presenter: Roger Hedding  |  Time: TBD
Paper author: Roger Hedding

Over four years ago, realizing that protection and control were melding together, PSRC officers approached the PES Technical Council with a proposal to combine the C0 Subcommittee on Data Acquisition, Processing & Control Systems with PSRC H Communications Subcommittee. This started an entire PES Technical Council reorganization effort that has been put in place and is commencing at the July 2016 PES General Meeting. This presentation will address what is the reorganization, what has changed, and how this organization effects the protection and control standardization process.

Combining subsynchronous oscillations detection and synchrophasor measurements to increase power system stability

Presenter: Roger Hedding  |  Time: TBD
Paper authors: Roger Hedding, V. Madani (PG&E), Galina Antonova

This presentation will review the subsynchronous oscillation phenomena and the interactions between the electrical power system and the mechanical turbine generator system. It describes subsynchronous oscillation detection algorithms and special filters’ designs, and presents an application that combines subsynchronous oscillations detections with synchrophasors streaming.  Finally, some results will be given showing the applications, simulation results and field experience in several power systems.

Mitigating transformer tank rupture: A relay engineer's challenge

Presenter: Ilija Jankovic  |  Time: TBD
Paper authors:
Ilija Jankovic and Roger Hedding

Expensive, and in many cases unrepairable, ruptures of power transformer tanks are caused by lengthy clearing of internal faults which can be avoided with the choice of the correct protection algorithm. Insulation of power transformer winding can break down at any time, causing significant ground fault current, especially in strong and solidly grounded power systems, as is the case with most power transmission systems. This presentation will explain the proposed protection algorithm in detail.

Life cycle considerations for microprocessor relays

Presenter: Michael Kleman  |  Time: TBD
Paper authors:
Michael Kleman, Todd Moyer P.E. (Metropolitan Edison Company)

The understood and average microprocessor relay life span is on the order of fifteen years.  During the course of this life span, there are inherent costs associated with the maintenance of these devices which are generally not considered but are critical to the performance of the device and the intended application. This presentation examines the planned costs associated with such things as NERC testing requirements and manufacturer or customer specific non-critical firmware enhancements.

Benefits of open standards based process bus architectures and how to protect them

Presenter: Peter Rietmann  |  Time: TBD
Paper authors:
Steve Kunsman, Peter Reitmann, Herb Falk (Sisco Inc.), Chan Wong (Entergy)

This session discusses different architectures and the benefits of process bus solutions based on open standards, results and field experiences involving the NCIT, combined with the flexibility and modularity of the stand-alone merging units for process bus IO system. As well, the paper will cover security architectures to ensure highest availability of IEC 61850-9-2 solutions.

Adventures on the smart grid

Presenter: Denzil Radford  |  Time: TBD

The term “Smart Grid” often conjures up images of a complete transformation of the utility grid along with the associated financial implications. This mindset has led many managers of utility grids to put off the implementation of any grid modernization investments beyond what is demanded by key customers. The reality of grid modernization is that the implementation can be accomplished by deploying advanced technologies incrementally to accomplish very specific goals. This poster will provide an overview of applications that can be executed using technologies such as sensors, automation devices, and communication technologies. Examples of actionable Smart Grid events will be presented, and the step by step self-healing response of the system will be described.

Increasing grid capacity to connect distributed energy resources

Presenter: Steve Kunsman  |  Time: TBD
Paper authors: 
Steve Kunsman, Goran Leci, Peter Kreutzer

The poster will present an approach on how enhanced operation of the distribution grid improves with the automation deeper in distribution grid in a cost-effectively and proofed way. Volt/VAr optimization refers to the optimization of reactive power and voltage regulation resources on the distribution system for the purpose of power factor correction, voltage correction, conservation voltage reduction, or loss reduction. Optimized VAr flow improves power factor and can result in substantial savings in cost of energy and infrastructure utilization. Optimized voltage improves power quality by preventing over-under voltage conditions and achieving a flatter voltage profile along circuits. 

High penetration renewable power microgrids

Presenter: Nathan Adams  |  Time: TBD

In order to reduce greenhouse gas emissions, lower the kWh cost of energy to their customers and wean themselves from the use of fossil fuels, a number of remote and island communities are investing in renewable generation. Wind and solar resources are abundant and inexhaustible. Generating power from these resources can create jobs, improve public health, and mitigate environmental impact. However, these renewable sources present a number of challenges to power grid operators. This poster will discuss how to mitigate these challenges. 

Cyber security - Security strategy for electricity distribution management system and security architecture considerations

Presenter: Sukumara Shetty  |  Time: TBD

This  poster will cover some of the strategies and methods in creating effective cyber security architectures for substation and distribution automation systems which are robust enough to withstand cyber-attacks in the first place and resilient enough to recover in the event of security compromise.
