Title PI
Frequency Response Standard

NERC BAL-003-1 (Frequency Response Standard) has two main objectives: To require sufficient Frequency Response from the Balancing Authority (BA) to maintain Interconnection Frequency within predefined bounds by arresting frequency deviations and supporting frequency until the frequency is restored to its scheduled value; and to provide consistent methods for measuring Frequency Response and determining the Frequency Bias Setting.

Martinez, Carlos
Frequency Responsive Demand

This project is exploring methods by which loads can be aggregated into a grid-friendly network of actively configured, autonomous responses to self-sense frequency and voltage fluctuations, and provide a full range of ancillary services—including virtual inertia, regulation, ramping, spinning reserve, and emergency curtailment capabilities.

Kalsi, Karan

Buckner, Mark
Grid Performance Metrics (GPM) Real-Time Monitoring Tool

The MISO-GPM tool was research, prototype and is being field tested at MISO. GPM estimates Grid’s voltage, stability, and thermal performance metrics using model-less algorithms and MISO grid phasor data within MISO phasor infrastructure. Grid performance metrics are presented to MISO Operations in real time geo-graphic multi-view displays and in an automatic deliverable daily reliability performance report.

Martinez, Carlos
Grid Reliability Metrics

The project builds upon earlier work to assess current available metrics, perform a comparative assessment of data on metrics used by different Independent System Operators (ISOs) and regions, identify gaps in available metrics, define metrics needed to address all elements of the grid and markets, validate the metrics with industry stakeholders, develop prototypes using CERTS technology platform for performance monitoring, field test, implement and perform periodic comparative assessments.  

Dyer, Jim
Improved Oscillation Detection for Alarming and Daily Summary Reports

This project is enhancing a spectral coherence algorithm to improve the detection of persistent oscillations in the power system in a manner that will provide better information on the characteristics of these oscillations to the end user. This phase of work will refine the approach by investigating new algorithms for the oscillation detection within the DISAT framework, as well as further investigating the use of the statistical quantities to aid in alarming.  

Tuffner, Frank
Information Management for Grid Control

This research focused on control issues associated with the bulk power system—initially control-area management and transmission reliability. This project aimed to develop an information flow model for interchange schedules and real-time grid operating data, and to develop a description of the concepts and relationships that can exist in an agent community for information management.  

Smathers, Douglas C.
Integrated Security Analysis

This project was designed to investigate alternative frameworks for the integration of these tools into a comprehensive package that can be more responsive to changing conditions and simultaneous transactions.  These frameworks aimed build on the availability of raw data from existing security tools both static and dynamic.

Sauer, Pete
Integration of Variable Renewable Generation

FERC staff commissioned LBNL to study how a critical aspect of reliability—the control of power system frequency during the period immediately following the sudden loss of a large conventional power plant—can be better measured to assess the adequacy of frequency control in the interconnections currently and be used to manage the reliable integration of new resources, including variable renewable generation.

Intelligent Alarms Tool: Disturbance Alarm, Response, and Analysis (DARA)

The NERC-IA real-time tool is an automatic, integrated process to identify abnormal interconnections load-generation unbalances, and broadcast intelligent alarm descriptions together, possible root-causes, and recommend preventive actions to Reliability Coordinators, Operations Management, and Regulators.

Martinez, Carlos
Interactions of Environmental Policies in a Transmission-constrained Competitive Electric Market

This project was designed to address several emerging issues for the Western US and the context of the WECC: (1) Will multiple concurrent market-based policies necessarily benefit renewable producers at the expense of consumers and coal-based producers? (2) What is the relationship among prices of electric energy, emissions permits, and renewable energy credits (RECs)? (3) Will multiple concurrent market-based policies grant a greater magnitude of incentive for companies to manipulate markets in their favor (i.e., market power)?

Load as a Resource Scoping Studies

CERTS assembled an interdisciplinary team to assess the research needs associated with a range of topics related to the use of load (or demand response) as a system reliability resource, mainly to provide ancillary services.

Eto, Joe
Load as a Resource Technical Assistance

This project provided technical assistance to ISO-NE on design and implementation of a Demand Response Reserves Pilot project, to NYISO on aspects of the real-time pricing programs operated by the utilities in the state, and to PJM’s demand response staff and system operators to facilitate the implementation of new market rules to enable customer loads to directly provide spinning reserve and regulation services.

Goldman, Charles
Load-Generation Control Performance Standards (NERC BAL-001 and BAL-002)

The purpose of BAL-001(-1) (Real Power Balancing Control Performance) is to maintain Interconnection steady-state frequency within defined limits by balancing real power demand and supply in real time. The purpose of BAL-002(-1) (Disturbance Control Performance) is to ensure the Balancing Authority is able to utilize its Contingency Reserve to balance resources and demand and return Interconnection frequency within defined limits following a Reportable Disturbance.

Martinez, Carlos
Long-Term Planning and Investment for Transmission and Generation

This project was designed to investigate how the presence of forward contracts affects the behavior of suppliers in real-time markets, how suppliers and buyers determine an equilibrium between forward and real-time sales, how the volatility of spot prices affects the levels of investment in new generation capacity and demand-side response, and how to provide incentives for transmission, generation and distributed energy resources (including load response) to maintain acceptable standards of reliability in the supply system (i.e. maintain system adequacy).

Mount, Tim
Managing Uncertainty in the Modern Power System: from Algorithms to Market Design

This research aims to develop novel algorithmic tools to efficiently manage the variability that renewable energy resources bring to bear on power system operations at scale. Specifically, this work aims to (1) develop distributionally robust control algorithms to enable the near-optimal dispatch of uncertain power networks; and (2) design stochastic market clearing mechanisms to provide a competitive medium through which renewable power producers can sell their variable supply on equal footing with conventional power producers and flexible demand.

Shulze, Bill
Market Power Monitoring Metrics with Visualization

Market power gives certain market participants the ability to manipulate the market to their advantage.  In our research we identify resources which have the potential for market power either individually or within a small group based on sensitivity information that can be obtained from an optimal power flow.  Specifically we cluster generators with the ability to adjust prices without affecting dispatch, potentially enabling them to set prices.  This project was designed to develop and demonstrate robust algorithms that can be applied to ISO-scale systems.

Lesieutre, Bernie
Measurement Error Impacts on Synchrophasor-Based Applications

This activity encompasses assessing the impact of measurement errors on synchrophasor measurement unit (PMU) applications. IEEE Standard C37.118 defines the accuracy requirements for PMUs. Frequency and angle errors from the standard is used in the error analysis. Four areas have been identified for the initial assessments: event location detection, oscillation detection, islanding detection, and dynamic line rating.

Liu, Yilu
Measurement of Phasor-like Qualities

Devices called Phasor Measurement Units (PMUs) report the values of (for example) amplitude, frequency and phase of the power system. These parameters describe a mathematical entity called a phasor.  But the power system quantities are not phasors—they are 'phasor-like.' Their frequency and amplitude are not constant, and constant parameters are a requirement of a phasor. Further, the word phase is not even defined as a parameter relating two signals of different frequencies, and yet that is a required output of a PMU.
