Mesh-Grids (11/2016)

Author: Art Villanueva

Mesh-type grid arrangements introduce the inclusion of loops in the architecture, and eliminate nodal parent-child relationships such as those seen in fractalgrids and traditional microgrids. In addition, any microgrid node in a mesh-grid can act as a sibling to an interconnected microgrid. Each node, whether a microgrid, virtual power plant, or any distributed energy resource (DER), is identified as a peer and equally a participant in the energy cloud, ushering in a new era of collaborative consumption for energy in a sharing economy.

Transactive Energy Challenge: Energy Management in Microgrid Systems (2016)

Authors: Jennifer M. Worrall, Edward G. Cazalet, PhD, William T. Cox, PhD, Narayanan Rajagopal, Thomas R. Nudell, PhD, and Paul D. Heitmann

There has been extensive work in the abstract TE model as well as other standards based on Energy Interop, such as the Transactive Energy Market Information Exchange (TeMIX). However, we have yet to see a pilot demonstration that proves the efficacy of this mechanism in the context of a microgrid.

The output of this team’s work in the TE Challenge is the framework for an open-source, open-standards, Java-based implementation of the TeMIX platform, from use cases and requirements to a sample architecture for both Market Participants and a Market Facilitator. This will provide the basis for a live implementation of the Transactive Energy concepts in the next phase of the Transactive Energy Challenge.

Considerations for Designing and Operating Transactive Grids and Microgrids (2016)

Authors: Edward G. Cazalet, William T. Cox, Toby Considine, Jennifer M. Worrall

We describe some considerations for applying transactive energy to microgrids and grids. A broader view of business and policy approaches, in addition to practical application considerations, will help design and build more robust grids. For example, decoupling and avoiding assumptions of uniform objectives is important for all grids.

Establishing Communication and Power Sharing Links Between Components of a Distributed Energy System (2015)

Authors: Art Villanueva, Jennifer M. Worrall

This patent application is a method and system for sharing power or energy across various power supply and control modules. More specifically, disclosed are systems and methods for distributing energy. As explained, the method discloses receiving, at a microgrid, data from a plurality of data sources. The data is then analyzed to forecast power needs associated with the microgrids. Using the data, the microgrid may determine whether and when to share power with the requesting module.

Camp Pendleton FractalGrid Demonstration (2014)

Authors: Art Villanueva, Victor Fung, Jennifer Worrall, Jeff Trueblood

This was a California Energy Commission (CEC) Public Interest Energy Research (PIER)-sponsored grant for Harper Construction. This is a HEAVILY REDACTED VERSION. The full version is twice as long. Recent years have seen the rapid development of energy technologies such as advanced energy management systems. One such energy management system is the microgrid, a local energy grid with the ability to disconnect from the main grid and operate autonomously. In this project, the research team investigated the utility of a unique microgrid architecture concept called the FractalGrid, in which multiple microgrids are strategically arranged in a fractal, or recursive, pattern. The FractalGrid configuration has the potential to deliver clean, secure, and affordable energy security in localized areas throughout California by managing energy sources and storage and by distributing energy efficiently to identified use cases. This concept has peak shaving and load management capabilities, and has the ability to maintain critical loads at times of low energy availability, as well as the ability to shift energy use in order to level out energy use profiles during peak hours of utility-grid energy pricing. The Camp Pendleton FractalGrid Demonstration project is a proof of concept that realizes much of the promise of FractalGrid architectures and serves as a basis for further microgrid-enablement of the entire base. The project integrates energy storage and distributed renewable energy sources with an advanced software system to create a sustainable solution for utility-scale establishments that require a stable energy input. The research team installed and successfully tested four fractal microgrids with the capacity to operate autonomously as well as in concert with a parent microgrid at Camp Pendleton. The microgrids enhanced stability and reliability throughout the power network, demonstrating a new method for California energy management.

Architecting Critical Infrastructure Protection for the Energy Sector and Beyond (2012)

Authors: Robert M. Peabody, Arturo N. Villanueva, Jr.

This paper is the culmination of a capstone project executed for Northrop Grumman and UCSD. Utilizing a well-designed enterprise architecture, this paper describes compliant physical and cybersecurity and enhanced perimeter surveillance and remote monitoring solutions to protect the critical infrastructure of the power generation energy industry.

Where possible, we endeavor to utilize existing industry legacy protection systems currently in place to save customer costs and streamline time to market. Featuring enhanced infrastructure awareness and rapid decision-making support, the solution achieves Department of Energy (DOE) Critical Infrastructure Protection (CIP) standards compliance, meets rapid time to market goals, delivers best value COTS solutions and feature a highly adaptable framework to accommodate future infrastructure growth and manage complexity.
