Wide-Area Damping Control Proof-of-Concept

The primary objective of this project is to design and demonstrate a prototype control system for damping inter-area oscillations in large-scale interconnected power systems. This is a collaborative effort involving the Bonneville Power Administration (BPA), Sandia National Laboratories, and Montana Tech University. The damping control strategy employs real power injections at strategically located points in the grid based upon real-time Phasor Measurement Unit (PMU) feedback.

Voltage Stability Applications Using Synchrophasor Data

The main objective of this project is to develop a voltage stability margin computation method using PMU data. The approach is to use the PMU data to estimate the Thevenin equivalent voltage and reactance, allowing a smaller size system to be analyzed for real-time stability application. Simultaneously, a new steady-state voltage stability technique called the AQ-bus method has been developed, which benefited this proposed voltage stability method. The program was handed over to BPA to allow for calculation, in an off-line capacity, of stability concerns.

This project focused on data quality on the real-time market operations of a power system.  In particular, the project addressed the following pertinent issues: (i) in the presence of bad data, to what degree that real-time locational marginal prices are affected? (ii) What are the worst scenarios of bad data that have the most significant impact on real-time prices of electricity? (iii) What are the effects of analog and digital forms of bad data? (iv) What are the potential risks on market operations from cyber data attacks?

Technical support for revisions to NERC Standard BAL-003

LBNL contractors John Undrill, Energy Mark, and Advanced System Research, participated in a variety of technical support activities leading to the revisions to NERC Standard BAL-003. As a result of these efforts the NERC Standard BAL-003 contains for the first time requirements for interconnection frequency response and creates obligations for balancing authorities to maintain minimum levels of frequency response.

SuperOPF Optimization Solver Enhancement

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.

Scoping Study on Research and Priorities for Distribution-System Phasor Measurement Units

This study addresses the potential use of phasor measurement units (PMUs) within electricity distribution systems, and was written to assess whether or not PMUs could provide significant benefit, at the national level. We analyze examples of present and emerging distribution-system issues related to reliability, integration of distributed energy resources, and the changing electrical characteristics of load. We find that PMUs offer important and irreplaceable advantages over present approaches.
