# Dynamical modelling of cascading failures in the Turkish power grid

## TL;DR

This paper introduces a novel dynamical model of the Turkish power grid that accounts for its topology and load distribution, revealing how centralized generation increases failure risk and highlighting conflicts between capacity and stability.

## Contribution

It presents the first model integrating dynamical properties and complex network topology to analyze cascading failures in the Turkish power grid.

## Key findings

- Network damage depends on load and generation distribution.
- Centralized generation is more susceptible to failures.
- Economic transmission capacity considerations conflict with grid stability.

## Abstract

A reliable supply of electricity is critical for our modern society and any large scale disturbance of the electrical system causes substantial costs. In 2015, one overloaded transmission line caused a cascading failure in the Turkish power grid, affecting about 75 million people. Here, we analyze the Turkish power grid and its dynamical and statistical properties. Specifically, we propose, for the first time, a model that incorporates the dynamical properties and the complex network topology of the Turkish power grid to investigate cascading failures. We find that the network damage depends on the load and generation distribution in the network with centralized generation being more susceptible to failures than a decentralized one. Furthermore, economic considerations on transmission line capacity are shown to conflict with stability.
