Advanced Protection Packages for the Interconnection of Distributed Renewable Energy Resources

Mike Kockott, Hitachi Energy

It's getting common in modern power systems that long AC overhead lines and cables have several sections with varying parameters. They have large series impedance and also quite large and distributed capacitance to ground. Such complex installations introduce both magnitude change and phase angle shift for phase current along the line length. Therefore, when traditional line differential protection is used, it will measure quite large false differential current during normal operating conditions. The model-based differential protection takes into account the exact information about the protected object, which is modeled within the relay by using sequence matrices. Based on the model and local measurements, the expected remote end phase currents can be accurately estimated. This effectively provides exact charging current compensation when these estimated currents are compared with actual currents from the remote end, which are measured via a communication link. As result, the model-based differential protection pickup can be set quite sensitively, irrespective of the protected object properties.

Facility Relocations – Negotiating Success

Manuel Silveira, Jack Barrett, Burns & McDonnell

Facility relocations—the act of relocating utilities due to third-party DOT or municipal requirements in continued use of public ROW—are a necessary part of utility operations. Often these relocations are a nonreimbursable cost to the utility and a cost that can be surprising or detrimental to normal business needs. The party requesting the relocation will provide an ask based on guidelines that can be conservative or confusing to navigate by those (specifically electric utilities) that may not be familiar with the world of DOT requirements and standards. Bringing a team of utility and transportation engineers together to help facilitate successful negotiation of minimized utility relocations customized for each situation can provide significant benefit to the utility that can drive costs down upwards of 90%. Our team will provide real-world examples of successful negotiation and planning tactics that have saved utilities around the country millions in construction costs.

Case Study: Consolidating Monitoring with Protection

Mike Ramlachan, GE Vernova

Today’s disturbance monitoring and reporting requirements provided by FERC and NERC, or else individual regional reliability organizations are typically defined by PRC-002-2 for Bulk Electric System (BES). Similarly, PRC-028-1 defines monitoring and reporting requirements for invertor-based resources. This paper will discuss the similarities and differences between PRC-002-2 and PRC-028-1. With advancements in today' s technology, one can argue the benefits of consolidating monitoring and protection to be able to meet the above monitoring and reporting requirements. This paper will discuss a case study of including monitoring within protection and control devices to meet these requirements. These requirements include minimum sampling rate, fault and disturbance record lengths, sequence of event record lengths, time sync and continuous record length.

Overview and Applications of Secure Routable Goose and Sample Values

Mark Adamiak, PCItek

Overview and Applications of Secure Routable GOOSE and Sample Values. The IEC 61850 standard defined a multicast communication protocol known as the Generic Object-Oriented Substation Event, or GOOSE. GOOSE only had Layer 2 (ethernet) addressing and thus could not pass through a router. In the most recent version of the standard, a routable and secure version of GOOSE has been defined, known as R-GOOSE. This paper presents an overview of R-GOOSE with security, architecture, and several potential applications.

An Introduction to the ASCE Solar PV Structures Manual of Practice

Steve Gartner, HDR, Inc.

Solar Photovoltaic (PV) systems are relatively new to the power generation industry, compared to established systems like nuclear, gas, and coal-fired facilities. As with any new technology, there is a learning curve for the industry to establish itself and develop methods for the design and construction of the systems. Although the structural systems of solar PV systems do not require large or heavy structural elements, there are unique challenges that solar PV structural and geotechnical engineers face daily. These challenges do not exist in other industries and currently, the US solar industry operates without solar-specific structural consensus standards or codes to guide engineers, owners, manufacturers, developers, and contractors on how to design and build solar PV structures. Design engineers and manufacturers rely on local building codes or any literature they can find to design these unique structures. Since there is no consistent way to design solar PV structures, it is left up to the interpretation of the Engineers of Record (EORs), who are using standards and guidelines that were developed for other industries.

To provide a more reliable and consistent approach to the design of solar PV structures, the American Society of Civil Engineers (ASCE), through its Structural Engineering Institute (SEI), created the Solar PV Structures Committee in 2020. This committee comprises structural engineers, geotechnical engineers, contractors, tracker manufacturers, wind specialists, solar developers, and owners. The committee has been working together for the past four years to develop an ASCE Manual of Practice. This Manual, although it is not a standard, will guide engineers on how they can rationally design solar PV structures for ground-mounted PV, elevated PV, rooftop PV, and floating PV systems. This presentation will discuss the unique aspects of solar PV structural systems, introduce the Solar PV Structures Committee, and provide an overview of the main topics covered in the soon-to-be-published ASCE Solar PV Structures Manual of Practice. Although the presentation will be geared toward structural and geotechnical engineers, all stakeholders involved in solar PV systems and power generation, including owners, developers, contractors, and engineers, will benefit from attending.
