Understanding, simulating and predicting the behavior of overhead lines and their supporting structures (including electrical towers) is essential for securing grid maintenance and extending asset life. Phlowers provides tools to achieve this in a simple way, despite the complexity of the underlying algorithms.

Phlowers is an Open Source ecosystem that brings mechanical and thermal modeling of overhead lines to engineers, researchers and operators, including those working offline. In the future, it will integrate the modeling of supporting structures (pylons/towers) to simulate mechanical constraints and interactions within the grid.

The ecosystem currently includes Python libraries for simulations and an offline web application called Stellar. It enables users to customize models, integrate their own data and adapt tools to operational needs. It will also support large-scale batch computations to assess maintenance policies, simulate multiple scenarios and optimize long-term asset management strategies.

In this session, we will explore its architecture, use cases and contribution to innovation in grid asset management.
