Multifaceted Mathematics for Complex Energy Systems (M2ACS)
Project Director: Mihai Anitescu, Argonne National Lab
Goals:
• Taking a holistic view, develop deep mathematical
understanding and effective algorithms at the
intersection of multiple math areas for problems
with multiple math facets (dynamics, graph theory,
integer/continous, probabilistic …) for CES
• We do integrative mathematics to support a DOE
grand challenge while advancing math itself.
PICTURE
Integrated Novel Mathematics Research:
• Predictive modeling
• Mathematics of decisions
• Scalable algorithms for optimization and
dynamic simulation
• Integrative frameworks (90/10 vs 10/90
Mission; we identify the math patterns that will
enable the CSE applications.
Long-Term DOE Impact:
• Development of new mathematics at the
intersection of multiple mathematical subdomains
• Addresses a broad class of math patterns from
complex energy systems, such as :
• Planning for power grid and related
infrastructure
• Analysis and design for renewable energy
integration

New fundamental graph theory opportunity?
How do we concisely but comprehensively
for our goals parameterize graph
structure?
What are probabilistic models for graph
theory with “few parameters” that capture
the fundamentals of end-goal behaviors
(including evolution)?
What are graph metrics which are
“sufficient statistics” (both state and
topology) for our problems? –stats
mechanics analogy: the only “predictable
observables”
How do we know the resulting models are
consistent and sample from such models –
heterogeneous materials analogy?
Solution will likely involve: probability, data
analysis, optimization, graph theory,
dynamical systems
