Course description

Module 1:  Distribution network expansion planning (DNEP)

Lecturer: Bertrand Cornélusse

Supporting material can be found on the eCampus page of the course

Lecture 1: Introduction, optimal power flow and DNEP, non-linear models

  • Lecture :
    • Introduction to LP, MILP, NLP
    • Optimal Power Flow in a DC  microgrid
    • The DNEP problem
  • Hands-on session:
    • Implement DNEP in Julia (MINLP)

Lecture 2: Convex reformulations

  • Lecture :
    • Same problems as in lecture 1, we will understand how to reformulate these problems as convex optimization problems.

Module 2:  Planning and operation of distribution networks

Lecturers: Prof. Damien Ernst, Alizera Bahmanyar, David Vangulick.

 

Lecture 1: Using load-flows and state estimation for the planning and operation of distribution network (03-03-2023) – David Vangulick and Prof. Damien Ernst

In this class, we will review how load-flow and state-estimation tools are currently used for operating and managing distribution networks. Technical difficulties for using them will also be analyzed (need for pseudo-measurements,  difficulties associated with the IT infrastructure, etc.).  The class will also explain how to use  Pandapower for running load-flows and state estimations. The class will end by describing an advanced operational planning scheme currently used in the Belgian electrical distribution industry.

Lecture 2: Introduction to distribution networks. Modelling and tools for the planning and operation of distribution network (10-03-2023) – Alizara Bahmanyar and Prof. Damien Ernst.

Topics that will be addressed during this first class: (i) modelling of the electrical distribution network (ii) power flow analysis (iii) state estimation (iv) protections of distribution networks.

Lecture 3: Advanced methods for operating and planning distribution networks (17-03-2023). Prof. Damien Ernst

During this class, students will have to present three papers related to the advanced analysis, operation, and planning of distribution networks. Group of maximum three students for presenting one paper. Here are the three default papers:

Phase Identification of Smart Meters by Clustering Voltage Measurements

Active network management for electrical distribution systems: problem formulation, benchmark, and approximate solution

Short-term active distribution network operation under uncertainty

New papers can be suggested by the students but have to be approved by Prof. Ernst before.

Results of the presentations

Module 3: Reliability management of bulk electric power systems

Lecturers: Louis Wehenkel and Efthymios Karangelos

The logistics for teaching will be chosen at a later stage, depending on the evolution of the general situation. Links to reading material and slides will be added below, for each lecture.

Lecture 1: The classical concept of operational power systems security (24-03-2023). Louis Wehenkel

  • The notions of contingency and of power system response to contingencies
  • The Dy Liacco state diagram for power system operation
  • The N-1 reliability standard for power system operation
  • The SCOPF formulation of the preventive vs corrective security control tradeoff
  • Implications for operation planning, asset management, and system development activities

Lecture 2: Towards a consistent probabilistic risk management approach (31-03-2023). Efthymios Karangelos

  • Motivation: what’s missing in the N-1 approach?
  • Risk-based real-time operation: how to account for the (low) likelihood and potential impact of contingencies?
  • Planning under uncertainty: how to tackle the daily randomness of renewable power generation?
  • The need for resilience: what can go wrong will go wrong?

Lecture 3: Cyber-physical risk management of the bulk electric energy supply system (21-04-2023). LW & EK

Ahead in time, the students will be provided with a list of papers on cyber-physical security of electric power systems, and by groups of two students they will prepare a 15 minutes presentation of one of these papers (choice based on a first-come/first-served basis)

  • Student presentations per group/paper: 15 minutes of presentation + 15 minutes of questions and answers for each paper
  • Open discussions about current research challenges for cyber-physical risk management

Module 4: Sustainable organisation, integration, and migration

Lecturers: BC, DE, EK, LW

The last part of the course aims at getting the big picture by understanding how the overall system, coupling microgrids, distribution grids, and transmission grids, can function, be organised, and evolve so as to co-optimise competing targets, such as reliability, environmental acceptability, societal fairness, and economic attractiveness.

Lecture 1: Global grid and IT platforms (21-04-2023)

Part I: Planification for the EU electrical network. Lesson given by David Radu. Watch the video of the class he gave in 2021, focusing more on the Global Grid

Part II: Coordination between DSOs and TSOs, market platforms, congestion management and balancing. Lesson given by Damien Ernst.

Lecture 2: Organisational integration: who does what TSOs, DSOs, MOs, retailers… (30-04-2021)

Lecture 3: Research and development challenges (05-05-2023)

The students will have the opportunity to discuss with a group of experts from the industry & academia, who have kindly accepted to present their perspective on the modern  challenges for electric power system security management. The invited experts (in alphabetical order) are:

  1. Mr. Jean-Yves Bourmaud, Rte, France.
  2. Dr. Balthazar Donon, University of Liege, Belgium & Rte, France.
