Multi-time scale coordination of complementary resources for the provision of ancillary services

Christophe Salzmann, Colin Neil Jones, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Luca Fabietti

This paper presents a predictive control scheme for coordinating a set of heterogeneous and complementary resources at different time scales for the provision of ancillary services. In particular, we combine building thermodynamics (slow), and energy stora ...

A design method for distributed luenberger observers

Colin Neil Jones, Francisco Fernandes Castro Rego

The paper addresses the problem of designing distributed observers for discrete linear time-invariant (LTI) systems with distributed sensor nodes subjected to bounded measurement noise. A solution is proposed in terms of a distributed LTI Luenberger observ ...

Enhancing the dispatchability of distribution networks through utility-scale batteries and flexible demand

Mario Paolone, Colin Neil Jones, Tomasz Tadeusz Gorecki, Emil Namor, Fabrizio Sossan, Luca Fabietti

In this paper, the problem of dispatching the operation of a distribution feeder comprising a set of heterogeneous resources is investigated. The main objective is to track a power trajectory, called the dispatch plan, which is computed the day before the ...

Use of model predictive control for short-term operating reserve using commercial buildings in the United Kingdom context

Colin Neil Jones

Flexibility, particularly in terms of reserve services, is an essential requirement of power systems with high penetration of renewable electrical generation, which can reduce undesirable curtailment and enable higher integration of clean electrical power ...

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 ...

Active Directional Modifier Adaptation with Trust Region - Application to Energy-Harvesting Kites

Dominique Bonvin, Colin Neil Jones, Martand Singhal, Matthieu Jonin, Sanket Sanjay Diwale

Many real-time optimization schemes maximize process performance by performing a model-based optimization. However, due to plant-model mismatch, the model-based solution is often suboptimal. In modifier adaptation, measurements are used to correct the mode ...

Economic Advantages of Office Buildings Providing Ancillary Services with Intraday Participation

Ali Ahmadi Khatir, Colin Neil Jones, Faran Ahmed Qureshi, Ioannis Lymperopoulos

Controlling the consumption profile of office buildings can be used to provide balancing services to the power grid at a financial benefit without violating its thermal comfort constraints. The economic advantage of such a service is a reduction in the tot ...

Real-Time Optimization of Uncertain Process Systems via Modifier Adaptation and Gaussian Processes

Dominique Bonvin, Colin Neil Jones, Timm Faulwasser, Tafarel de Avila Ferreira, Harsh Ambarishkumar Shukla

In the context of static real-time optimization, the use of measurements allows dealing with uncertainty in the form of plant-model mismatch and disturbances. Modifier adaptation (MA) is a measurement-based scheme that uses first-order corrections to the m ...

Economic study of the participation of multiple energy resources in grid services markets

Colin Neil Jones, Tomasz Tadeusz Gorecki

This paper presents a method to analyze the technical and economic potential of combining different types of resources to provide grid services, with a particular focus on battery systems. The paper proposes a modelling paradigm where resources are describ ...

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

Colin Neil Jones, Faran Ahmed Qureshi, Ioannis Lymperopoulos, Altug Bitlislioglu

We demonstrate how charging infrastructure for electrical vehicles can be utilized for the provision of Ancillary Services to the Power Grid. Fast- charging stations that supply energy to vehicles at high power rates in- corporate energy storage to prevent ...

A coordinator-driven communication reduction scheme for distributed optimization using the projected gradient method

Georgios Stathopoulos, Colin Neil Jones

We propose a way to estimate the value function of a convex proximal minimization problem. The scheme constructs a convex set within which the optimizer resides and iteratively refines the set every time that the value function is sampled, namely every tim ...

Learning Proximal Operators with Gaussian Processes

Georgios Stathopoulos, Colin Neil Jones, Xuan Truong Nghiem

Several distributed-optimization setups involve a group of agents coordinated by a central entity (coordinator), altogether operating in a collaborative framework. In such environments, it is often common that the agents solve proximal minimization problem ...

Quantization Design for Distributed Optimization

Colin Neil Jones, Ye Pu, Melanie Nicole Zeilinger

We consider the problem of solving a distributed optimization problem using a distributed computing platform, where the communication in the network is limited: each node can only communicate with its neighbors and the channel has a limited data-rate. A co ...

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 ...

Complexity Certification of the Fast Alternating Minimization Algorithm for Linear MPC

Colin Neil Jones, Ye Pu, Melanie Nicole Zeilinger

In this technical note, the fast alternating minimization algorithm (FAMA) is proposed to solve model predictive control (MPC) problems with polytopic and second-order cone constraints. Two splitting strategies with efficient implementations for MPC proble ...

Constrained bundle methods with inexact minimization applied to the energy regulation provision problem

Colin Neil Jones, Tomasz Tadeusz Gorecki

We consider a class of large scale robust optimization problems. While the robust optimization literature often relies on structural assumptions to reformulate the problem in a tractable form using duality, this method is not always applicable and can resu ...

Data-driven Demand Response Modeling and Control of Buildings with Gaussian Processes

Colin Neil Jones, Xuan Truong Nghiem

This paper presents an approach to provide demand response services with buildings. Each building receives a normalized signal that tells it to increase or decrease its power demand, and the building is free to implement any suitable strategy to follow the ...

Convergence rates of moment-sum-of-squares hierarchies for optimal control problems

Colin Neil Jones, Milan Korda

We study the convergence rate of the moment-sum-of-squares hierarchy of semidefinite programs for optimal control problems with polynomial data. It is known that this hierarchy generates polynomial under-approximations to the value function of the optimal ...
