Module 2:  Planning and operation of distribution networks

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

Lectures will be given through the Webex platform, using the following link:

Lecture 1: Introduction to distribution networks. Modelling and tools for the planning and operation of distribution network (26-02-2021) – 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.

Podcast Lecture 1

Lecture 2: Using load-flows and state estimation for the planning and operation of distribution network (05-03-2021) – 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 with a description of an advanced operational planning scheme currently used in the Belgian electrical distribution industry.

Podcast Lecture 2

Lecture 3: Advanced methods for operating and planning distribution networks (12-03-2021). Prof. Damien Ernst

During this class, students will have to present three papers related to the advanced analysis, operation, and planning of distribution networks. All the papers will be put on the website one week before the class and will have to be read/studied by all the students in the class. 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.

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 (19-03-2021). 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

Further reading and background material

Lecture 2: Towards a consistent probabilistic risk management approach (26-03-2021). 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 (02-04-2021). 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.
