Tunable Experimental Testbed for Evaluating Load Coordination Methods

no code implementations21 May 2023 Drew A. Geller, Johanna L. Mathieu

Driven by the need to offset the variability of wind and solar generation on the electrical grid, development of load controls is a highly active field in the engineering literature.

Using Demand Response to Improve Power System Small-Signal Stability

no code implementations12 Apr 2023 Mengqi Yao, Sandip Roy, Johanna L. Mathieu

Our results show that shifting the load between buses, can improve a small-signal stability margin.

An Invariant Set Construction Method, Applied to Safe Coordination of Thermostatic Loads

no code implementations11 Feb 2022 Sunho Jang, Necmiye Ozay, Johanna L. Mathieu

In this paper, we introduce a strategy to obtain an implicit representation of a controlled invariant set for a collection of switched subsystems, and construct a safety-guaranteed controller to coordinate the subsystems using the representation.

Strategies for Network-Safe Load Control with a Third-Party Aggregator and a Distribution Operator

no code implementations3 Dec 2020 Stephanie C. Ross, Johanna L. Mathieu

Using this architecture, we propose two control strategies, which differ in terms of measurement and communication requirements, as well as model complexity and scalability.

Baseline Estimation of Commercial Building HVAC Fan Power Using Tensor Completion

no code implementations24 Apr 2020 Shunbo Lei, David Hong, Johanna L. Mathieu, Ian A. Hiskens

Commercial building heating, ventilation, and air conditioning (HVAC) systems have been studied for providing ancillary services to power grids via demand response (DR).

Effects of Load-Based Frequency Regulation on Distribution Network Operation

1 code implementation9 Jul 2018 Stephanie C. Ross, Gabrielle Vuylsteke, Johanna L. Mathieu

This paper examines the operation of distribution networks that have large aggregations of thermostatically controlled loads (TCLs) providing secondary frequency regulation to the bulk power system.

Real-Time Energy Disaggregation of a Distribution Feeder's Demand Using Online Learning

no code implementations16 Jan 2017 Gregory S. Ledva, Laura Balzano, Johanna L. Mathieu

We use an online learning algorithm, Dynamic Fixed Share (DFS), that uses the real-time distribution feeder measurements as well as models generated from historical building- and device-level data.
