Using Geographic Load Shifting to Reduce Carbon Emissions
Julia Lindberg, Bernard C. Lesieutre, Line A. Roald
An increasing focus on the electricity use and carbon emissions associated with computing has lead to pledges by major cloud computing companies to lower their carbon footprint. Da…
A Guide to Reducing Carbon Emissions through Data Center Geographical Load Shifting
Julia Lindberg, Yasmine Abdennadher, Jiaqi Chen +2
Recent computing needs have lead technology companies to develop large scale, highly optimized data centers. These data centers represent large loads on electric power networks whi…
Exploiting Symmetry in the Power Flow Equations Using Monodromy
Julia Lindberg, Nigel Boston, Bernard C. Lesieutre
We propose solving the power flow equations using monodromy. We prove the variety under consideration decomposes into trivial and nontrivial subvarieties and that the nontrivial su…
The Environmental Potential of Hyper-Scale Data Centers: Using Locational Marginal CO Emissions to Guide Geographical Load Shifting
Julia Lindberg, Bernard C. Lesieutre, Line Roald
Increasing demand for computing has lead to the development of large-scale, highly optimized data centers, which represent large loads in the electric power network. Many major com…
The Distribution of the Number of Real Solutions to the Power Flow Equations
Julia Lindberg, Alisha Zachariah, Nigel Boston +1
In this paper we study the distributions of the number of real solutions to the power flow equations over varying electrical parameters. We introduce a new monodromy and parameter…
RTO Frequency Regulation Market Clearing Formulations and the Effect of Opportunity Costs on Electricity Prices
Adria E. Brooks, Bernard C. Lesieutre
The Regional Transmission Operators each have unique methods to procure frequency regulation reserves used to track real power fluctuations on the grid. Some market clearing practi…
A Locational Price for Power Injection Fluctuations of Variable Generation and Load
Adria E. Brooks, Bernard C. Lesieutre
In this paper we calculate the incremental system production cost associated with a measure of locational power injection uncertainty that can be interpreted as a locational price…
The Power Grid Library for Benchmarking AC Optimal Power Flow Algorithms
Sogol Babaeinejadsarookolaee, Adam Birchfield, Richard D. Christie +20
In recent years, the power systems research community has seen an explosion of novel methods for formulating the AC power flow equations. Consequently, benchmarking studies using t…
Safe control of thermostatically controlled loads with installed timers for demand side management
Nishant Mehta, Nikolai. A. Sinitsyn, Scott Backhaus +1
We develop safe protocols for thermostatically controlled loads (TCLs) to provide power pulses to the grid without a subsequent oscillatory response. Such pulses can alleviate powe…
A Sufficient Condition for Power Flow Insolvability with Applications to Voltage Stability Margins
Daniel K. Molzahn, Bernard C. Lesieutre, Christopher L. DeMarco
For the nonlinear power flow problem specified with standard PQ, PV, and slack bus equality constraints, we present a sufficient condition under which the specified set of nonlinea…
