Computing Scaled Relative Graphs of Discrete-Time LTI Systems: A Frequency-Domain Approach
Guoming Shi, Fredy Ruiz
The scaled relative graph (SRG) represents the joint gain and phase properties of an input--output operator in the complex plane. This paper characterizes the SRG closure of causal…
SMGO-: Balancing Caution and Reward in Global Optimization with Black-Box Constraints
Lorenzo Sabug, Fredy Ruiz, Lorenzo Fagiano
In numerous applications across all science and engineering areas, there are optimization problems where both the objective function and the constraints have no closed-form express…
SMGO: A Set Membership Approach to Data-Driven Global Optimization
Lorenzo Sabug, Fredy Ruiz, Lorenzo Fagiano
Many science and engineering applications feature non-convex optimization problems where the objective function can not be handled analytically, i.e. it is a black box. Examples in…
Limiting gaming opportunities on incentive-based demand response programs
José Vuelvas, Fredy Ruiz, Giambattista Gruosso
Demand Response (DR) is a program designed to match supply and demand by modifying consumption profile. Some of these programs are based on economic incentives, in which, a user is…
A novel incentive-based demand response model for Cournot competition in electricity markets
José Vuelvas, Fredy Ruiz
This paper presents an analysis of competition between generators when incentive-based demand response is employed in an electricity market. Thermal and hydropower generation are c…
Rational consumer decisions in a peak time rebate program
José Vuelvas, Fredy Ruiz
A rational behavior of a consumer is analyzed when the user participates in a Peak Time Rebate (PTR) mechanism, which is a demand response (DR) incentive program based on a baselin…
