Title PI
Adaptive Islanding Demonstration in the Western Electricity Coordinating Council

This project developed an integrated algorithm to identify a cutset for a large power system for the application of a slow coherency based controlled islanding scheme. Controlled islanding is employed as a corrective measure of last resort to prevent cascading outages caused by large disturbances. The large scale power system is represented as a graph and a simplification algorithm is used to reduce the complexity of the system.

Vittal, Vijay
Agent-Based System Planning and Market Assessment

This task was focused on the development of a next generation computation/simulation tool that may be of use to the emerging industry. A joint effort between Cornell, Sandia, and Carnegie Mellon University, this project involved agent design as well as software development and testing.

Air Conditioner Testing

SCE and BPA have been conducting tests of individual residential and small commercial AC units to determine the conditions under which they stall.

Application of VARPRO to Ambient Mode Estimation

Research into the application of a VARPRO-based approach to modal analysis of ambient data from the power grid may improve on existing methods to estimate system damping. This would increase situational awareness of potential system instabilities.  Initial exploratory work has involved a first pass at recently acquired data, which shows promising results that warrant further investigation.  Direct application of VARPRO curve-fitting provides excellent results compared to brake-test ringdown.

Automatic Reliability Reports (ARR)

The FERC-NERC ARR tool was researched, prototyped and developed for FERC for automatically broadcast daily, monthly and yearly summary, or on-demand, reports on interconnections historical load-generation resource adequacy and control performance. ARR provides summaries of key reliability metrics, statistical analysis and trends. ARR also provides the starting point for understanding and analyzing reliability performance of each interconnection, identifies reliability performance trends that require corrective action, and facilitate evaluation for reliability standards adequacy.

Baseline Studies and Analysis

This project is also examining phase angles that are measured across the footprints of the same four ISOs in the Eastern Interconnection. It incorporates advanced statistical data processing techniques to identify trends in (or patterns involving) multiple phase angles, which are difficult to identify using standard analysis approaches.

Amidan, Brett
Benchmarking and Integrating Chance-Constrained Stochastic Unit Commitment Solution for Optimal Management of Uncertainty

This project is exploring approximate optimization methods to improve security-constrained unit commitment (SCUC) by: (a) developing robust scenario-reduction methods with assessment of impact optimality of the SCUC solution; (b) including contingencies in the SCUC formulation in addition to wind uncertainty; and (c) implementing the approximate-solution method for larger systems, while maintaining reasonable solution times.

Anderson, Lindsay
Business Model for Retail Aggregation of Responsive Load

This research project is exploring a proposed change in market design (and a corresponding business model) aimed at mobilizing the available flexibility of certain loads through proper incentives, and an aggregation scheme which will provide flexible resources to mitigate the uncertainty of variable energy resources (VERs)—allowing VERs to internalize the cost of uncertainty by contracting with responsive load (DR).

Oren, Shmuel
Candidate Frequency Events Monthly Reports Tool

The NERC-CFER tool was researched, prototyped and developed for NERC and is part of its Frequency Response standard process. For each interconnection, using phasor and SCADA data, identifies and delivers every month candidate critical frequency events including for each event, its frequency profile and most significant performance parameters. From CFER’s monthly reports NERC reliability subcommittees select the set of events that each Balancing Authority (BA) must use to measure and report its yearly Frequency Response Obligation.

Martinez, Carlos
Centerpoint Voltage Dip Events

Power quality recorders were placed on ten distribution feeders of the Centerpoint system in 2011.  1381 events were observed in the summers of 2011 through 2013. Many of these events were small voltage changes and single-sample spikes that, while of interest for other purposes, do not relate to the FIDVR phenomenon.  A selector based on a voltage-time profile was used to choose events that might be of interest.

Of the 317 events that were selected:

CERTS Microgrid Test Bed Phase I

The Consortium for Electric Reliability Technology Solutions (CERTS) Microgrid Laboratory Test Bed project's objective was to ease the integration of small energy sources into a microgrid. The project developed and demonstrated three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of small generating sources. The following three techniques comprise the CERTS Microgrid concept:

CERTS Microgrid Test Bed Phase II

Phase II of the CERTS Microgrid Test Bed Project focused on prioritizing, developing and, as appropriate, demonstrating at bench-scale the needed additional technology enhancements required to further optimize the microgrid from the explicit perspective of enhancing the business case for microgrids. The microgrid technology enhancements that were studied included:

  1. Reduction of protection costs
  2. Reduction of DC storage costs
  3. Inclusion of AC storage
  4. Inclusion of non-inverter-based microsources

Commercialization of the SuperOPF Framework

The objective of the SuperOPF project is to develop a framework that will provide proper allocation and valuation of resources through true co-optimization across multiple scenarios. Instead of solving a sequence of simpler and approximate sub-problems, the SuperOPF approach combines as much as possible into a single mathematical programming framework with a full AC network and simultaneous co-optimization across multiple scenarios with stochastic costs.

Composite Load Model Sensitivity Study

In 2015, LBNL contracted with Mitsubishi Engineering to conduct the initial phase for a sensitivity study of the composite load model. The study was coordinated with the WECC Load Modeling Task Force and involved analysis of the transmission planning models used by Pacific Gas and Electric, PacifiCorp, Salt River Project, and Southern California Edison. Subsequent phases of this study are being funded by DOE through the CERTS program. 

Computational Needs for the Next Generation Electric Grid

The April 2011 DOE workshop Computational Needs for the Next Generation Electric Grid was the culmination of a year‐long process to bring together some of the Nation’s leading researchers and experts to identify computational challenges associated with the operation and planning of the electric power system. The presented papers from the workshop are collected in the published proceedings.

Continuous Data-Driven Model Development

The objective of this activity is to develop a learning system that adequately characterizes the dynamic performance of generators, loads, and storage devices connected to the electric grid. This includes electronically coupled devices and other low-inertia or no-inertia devices with nontraditional dynamic behaviors. The ultimate value for electric system operators is to reduce the uncertainty associated with DER, renewable generation sources, and loads.

Curated Power Grid Data Center for BPA

A curated power grid data repository (PGDR) will provide researchers and developers with access to fully-curated data sets with known data quality handled in an automated process using well-tested and well-documented algorithms. Such a data repository will make power system information as provided by participating Utilities available to a broad research community to enable future power systems research. This project is working to develop the requirements and initial specifications of a PGDR and provide some prototyping of the capability.
