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.

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)?

Framework for Assessing the Impact of Coordinated Aggregation of DER on Bulk Power System Performance

The overall objective of this project is to develop a framework to assess the impact on bulk power system performance of distributed energy resources (DERs) when coordinated (via an aggregator) to provide ancillary services (e.g., frequency regulation). Of special interest is understanding the potential negative effects of failures in channels utilized by the aggregator to exchange information with the individual DERs and the hardware used to implement the DER local control.

Domínguez-García, Alejandro
FIDVR Meetings and Workshops

In 2007, the utility industry approached DOE to discuss growing concerns they had regarding the potential impacts of FIDVR on grid reliability. DOE has co-sponsored three national workshops (in 2008, 2009, and 2015) with NERC to vet the topic with both the utility and air-conditioner manufacturing industries. These workshops are the precursor to the current DOE research initiative with industry on FIDVR.

FIDVR Load Modeling Tool

The purpose of this task is to generalize the load model development and calibration methodology developed for WECC to address the FIDVR phenomenon in planning studies.  Specifically, residential and commercial building load models must explicitly identify the load composition by electrical characteristics (i.e., static power, impedance, 1 and 3 phase motors, motor torque/speed characteristics, motor inertia, variable speed drive, and motor protection characteristics).

Etingov, Pavel
