Transmission and distribution systems were not historically engineered to accommodate energy storage, but a surge in rollout of the technology appears inevitable over the next decades. To help enable this aspect of the transition from the legacy to the next-generation electricity grid, standards development around energy storage has intensified.
IEEE has an array of more than 100 active standards or standards in development with relevance to the smart grid, and among those are several that directly pertain to energy storage. IEEE P2030.2™ “Guide for the Interoperability of Energy Storage Systems Integrated with the Electric Power Infrastructure” and IEEE P2030.3™ “Standard for Test Procedures for Electric Energy Storage Equipment and Systems for Electric Power Systems Applications” are among such standards-development projects, while the IEEE 1547™ Series of Interconnection Standards includes both active and in-development standards that have to do with energy storage.
The IEEE P2030.2 and IEEE P2030.3 development projects both grew out of the successful, two-year effort that yielded IEEE 2030® “IEEE Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS), End-Use Applications, and Loads.” As power, communication and Information Technology (IT) engineers collaborated on that foundational, cross-discipline interoperability guide, key areas of the developing smart grid that demanded more concentrated focus were revealed. Energy storage quickly emerged as one of them.
IEEE P2030.2 was launched in October 2010 to develop a standard that would facilitate wide-scale, consistent implementation of both discrete and hybrid energy-storage systems and their integration with the greater electric-power infrastructure. The standard is intended to define technical characteristics of the storage systems and their associated end-use applications and loads. In doing so, IEEE P2030.2 is designed to establish a go-to knowledge base for terminology, functional performance, evaluation criteria, operations, testing and application of engineering principles for energy-storage systems.
Work on IEEE P2030.3 began in February 2011. The goal is to provide hardware manufacturers, utilities, energy service companies and other industries and institutions with standardized test procedures with regard to verifying conformance of energy-storage systems to interconnection standards.
Expansion of the IEEE 1547 family of standards, amendments and standards-development projects has proceeded similarly, rippling out from development and real-world implementation of IEEE 1547 “Standard for Interconnecting Distributed Resources with Electric Power Systems,” published in 2003 and reaffirmed in 2008.
IEEE 1547 standards inform interconnection of storage systems around the world in valuable applications such as microgrids and distributed generation, and the lessons learned from these experiences in the field continue to fuel evolution of the family to better address market needs. For example, IEEE P1547.8™ “Recommended Practice for Establishing Methods and Procedures that Provide Supplemental Support for Implementation Strategies for Expanded Use of IEEE Standard 1547” is in development to extend the base IEEE 1547 standard to emerging storage technologies. The IEEE P1547a™ amendment, meanwhile, is also in development, to address voltage regulation and response to abnormal conditions of voltage and frequency.
In the case of IEEE P2030.2, IEEE P2030.3, the IEEE 1547 series and other energy-storage projects, IEEE standards are intended to establish interconnection requirements for any existing or future storage technology with which the grid might interact. While it is true that such standards ultimately help advance energy-storage technologies along to the marketplace for the benefit of humanity, the IEEE Standards Association’s role is to provide a forum in which industry experts can collaborate and develop the standards that they deem as necessary. In this way, it is global industry that drives IEEE standards, and it is the global marketplace that decides which of the many emerging energy-storage technologies see widespread uptake.
