Distributed Energy Systems: Security Implications of the Grid of the Future

Distributed Energy Resources (DER) are being added to the nation's electric grid, and as penetration of these resources increases, they have the potential to displace or offset large-scale, capital-intensive, centralized generation. Integration of DER into operation of the traditional electric grid requires automated operational control and communication of DER elements, from system measurement to control hardware and software, in conjunction with a utility's existing automated and human-directed control of other portions of the system. Implementation of DER technologies suggests a number of gaps from both a security and a policy perspective.

Microgrid Cyber Security Reference Architecture (V2)

This document describes a microgrid cyber security reference architecture leveraging defense-in-depth techniques that are executed by first describing actor communication using data exchange attributes, then segmenting the microgrid control system network into enclaves, and finally grouping enclaves into functional domains. To illustrate the design approach, two notional microgrid control implementations are presented. Both include a discussion on types of communication occurring on that network, data exchange attributes for the actors, and examples of segmentation via enclaves and functional domains. The second example includes results from Red Team analysis and quantitative scoring according to a novel system that derives naturally from the implementation of the cyber security architecture.

Methodology for Preliminary Design of Electrical Microgrids

Many critical loads rely on simple backup generation to provide electricity in the event of a power outage. An Energy Surety MicrogridTM can protect against outages caused by single generator failures to improve reliability. An ESM will also provide a host of other benefits, including integration of renewable energy, fuel optimization, and maximizing the value of energy storage. The ESM concept includes a categorization for microgrid value propositions, and quantifies how the investment can be justified during either grid-connected or utility outage conditions. In contrast with many approaches, the ESM approach explicitly sets requirements based on unlikely extreme conditions, including the need to protect against determined cyber adversaries. During the United States (US) Department of Defense (DOD)/Department of Energy (DOE) Smart Power Infrastructure Demonstration for Energy Reliability and Security (SPIDERS) effort, the ESM methodology was successfully used to develop the preliminary designs, which direct supported the contracting, construction, and testing for three military bases.
