Project abstract

Distribution grids are experiencing changes because of the integration of new loads, such as electric vehicles, and distributed generation such as solar panels. This represents a challenge to ensure the reliability of power supply. Proposed solutions often include the development of a cyber-physical system, where sensors generate data that enable operators to model the grid, or even to create a ”digital twin”. The processing of the collected data provides information that supports efficient decision taking, to keep the grid reliable, even with a high penetration of renewables and electric vehicles.

However, the installation of sensors and meters on a large scale might encounter three major issues: i) Economic issue: It might be unprofitable to install many sensors, compared to the benefits they provide. ii) Environmental issue: The collection, processing and storage of very large amounts of data can be power-intensive. ii) Technical issue: Adding equipment and functionality always carries a risk of giving rise to new failure modes as well as new uncertainties.

The objective of the PhD is to reflect on the value of data, and to adapt the ICT system accordingly, so that the physical grid evolves towards a smarter grid. The first step has been to establish the relations between data and grid performance. Then, two approaches have been identified: Approach 1: Use data already collected more efficiently and Approach 2: Explore how much additional data are needed to achieve a reliable smart grid.


Summary of work

2018.
Conception of the framework for the project: improvement of asset management in the power systems based on data analytics.
Selection of three main areas to investigate: i) prediction, ii) selection, iii) detection.

2019.
Work on the impacts of data quality on asset management decisions, and selection of an profitable level of investments in improved data quality.
Work on failure prediction at the component level using machine learning methods (research visit in Japan).

2020.
Literature review of algorithms that can be used for detection purposes in local power systems.
Work on failure prediction at the substation level.
Work on the elaboration of importance indices for components at the distribution level to support maintenance activities.

2021.
One journal paper written and submitted (failure prediction of an HVDC line without component-specific sensors).
Working on a program to convert time series measurement into CIM-XML files.
Work on a warning system using meter data, that sends an alarm to the DSO when household loads change significantly, and indicates the probable cause of the change.
