Rare desynchronization events in power grids: On data implementation and dimensional reductions
Tim Ritmeester, Hildegard Meyer-Ortmanns
We discuss the frequency of desynchronization events in power grids for realistic data input. We focus on the role of time correlations in the fluctuating power production and prop…
Belief propagation for supply networks: Efficient clustering of their factor graphs
Tim Ritmeester, Hildegard Meyer-Ortmanns
We consider belief propagation (BP) as an efficient and scalable tool for state estimation and optimization problems in supply networks such as power grids. BP algorithms make use…
The cavity method for minority games between arbitrageurs on financial markets
Tim Ritmeester, Hildegard Meyer-Ortmanns
We use the cavity method from statistical physics for analyzing the transient and stationary dynamics of a minority game that is played by agents performing market arbitrage. On th…
Rare extinction events in cyclic predator-prey games
Shannon R Serrao, Tim Ritmeester, Hildegard Meyer-Ortmanns
In the May-Leonard model of three cyclically competing species, we analyze the statistics of rare events in which all three species go extinct due to strong but rare fluctuations.…
State Estimation of Power Flows for Smart Grids via Belief Propagation
Tim Ritmeester, Hildegard Meyer-Ortmanns
Belief propagation is an algorithm that is known from statistical physics and computer science. It provides an efficient way of calculating marginals that involve large sums of pro…
Minority games played by arbitrageurs on the energy market
Tim Ritmeester, Hildegard Meyer-Ortmanns
Along with the energy transition, the energy markets change their organization toward more decentralized and self-organized structures, striving for locally optimal profits. These…
