Ancillary Services Provision Utilizing a Network of Fast-Charging Stations for Electrical Buses

Colin Neil Jones, Faran Ahmed Qureshi, Altug Bitlislioglu

Fast-charging stations that supply energy to electrical vehicles at high power rates may incorporate energy storage to avoid high currents to the grid and reduce peak-demand costs. We demonstrate the potential for utilizing such infrastructure for the prov ...

Regularized economic model predictive control with barrier functions

Colin Neil Jones, Altug Bitlislioglu

In this article, we consider the use of barrier functions as a regularizing cost in economic model predictive control (EMPC). We focus on a specific variant, EMPC with generalized terminal constraints (G-EMPC), as it is suitable for tackling large-scale pr ...

Experimental Implementation of Frequency Regulation Service Using Commercial Buildings

Colin Neil Jones, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Ioannis Lymperopoulos, Altug Bitlislioglu, Luca Fabietti

Frequency control reserves are a fundamental mechanism in the current electric power system to preserve the balance between demand and generation of active power at all times. The traditional approach is to exploit conventional power plants for frequency r ...

Interior Point Decomposition for Multi-Agent Optimization

Colin Neil Jones, Ivan Pejcic, Altug Bitlislioglu

In this paper we present the application of the interior-point decomposition (IPD) method, which was originally formulated for stochastic programming, to optimization problems involving multiple agents that are coupled through constraints and objectives. I ...

Robust Tracking Commitment

Colin Neil Jones, Tomasz Tadeusz Gorecki, Altug Bitlislioglu

Many engineering problems that involve hierarchical control applications, such as demand side ancillary service provision to the power grid, can be posed as a robust tracking commitment problem. In this setting, the lower-level controller commits a set of ...

On Coordinated Primal-Dual Interior-Point Methods for Multi-Agent Optimization

Colin Neil Jones, Altug Bitlislioglu

This paper presents a coordinated primal-dual interior point (PDIP) method for solving structured convex linear and quadratic programs (LP-QP) in a distributed man- ner. The considered class of problems represents a multi-agent setting, where the aggregate ...

Guaranteeing Input Tracking For Constrained Systems: Theory and Application to Demand Response

Georgios Stathopoulos, Colin Neil Jones, Tomasz Tadeusz Gorecki, Altug Bitlislioglu

A method for certifying exact input trackability for constrained discrete time linear systems is introduced in this paper. A signal is assumed to be drawn from a reference set and the system must track this signal with a linear combination of its inputs. U ...
