Operational Control of a Multi-energy District Heating System: Comparison of Model-Predictive Control and Rule-Based Control
This study focuses on operational control strategies for a multi-energy District Heating Network (DHN). Two control strategies are investigated and compared: (i) a reactive rule-based control (RBC) and (ii) a model predictive control (MPC). For the purpose of the study a small scale district heating network is modelled using Modelica. The production plant combines a heat pump, a gas boiler and a thermal solar field on the production side with a storage tank for flexibility purposes. On the cons…

"Schrimpf and his colleagues trained a model to generate sentences that, when read, would activate or suppress neural activity in the reader’s brain," exerting "noninvasive control over high-level brain activity" https://www.quantamagazine.org…

Guaraní is one of the most widely spoken Indigenous languages in the Americas.
A mother tongue of roughly six and half million people—in particular, in Paraguay.
There, most Paraguayans speak Guaraní or a mixture of Guaraní and Spanish, regardless of whether or not they are Indigenous Guaraní, mestizo, or white.
Paraguay is the only country in the Americas where a Native American language has resisted assimilation into Spanish or Portuguese,
and where its very use w…

Hat tip to John Kemp for admitting that he was wrong to blame Spain's blackout on excessive reliance on inverter-based renewables and insufficient inertia, and 👏 for his very decent explainer on what actually happened. https://jkempenergy.com/2025/06/19/spa

Spain’s blackout blamed on poor voltage control
19 June 2025 Spain’s massive blackout was caused by overvoltage on the transmission system and the failure of the country’s generators to compensate by absorbing more reactive power, according to t…
