Classic tit-for-tat between the US and Denmark with the added benefit of propping up struggling fossil firms

Is indonesias grid operator ready to connect all those turbines to the mainland grid? Who is going to finance these assets?

A pegada de carbono e as margens térmicas dependem da disponibilidade de GNL e gás, mas são menos dominantes mês a mês do que em secas anteriores.

Espere spreads de pico mais apertados quando o vento tiver baixo desempenho e durante restrições de transmissão; suavização fora do pico quando a energia solar/eólica estiverem alinhadas.

O que isso significa para os preços e o despacho:

A energia hidrelétrica de reservatório está se tornando cada vez mais um “amortecedor” flexível, moldando os picos e preservando a água em períodos de seca.

Isso evidencia que o crescimento da VRE está amenizando a escassez hidrelétrica, em vez de aumentar o despacho térmico.

🗣️ “Brazil has established itself as a global clean power leader,” says Ember’s Dr Raul Miranda

However the sparse digital infrastructure in the grid is often the greatest bottleneck! Will the #AI revolution in energy systems cut short by aging grids?

The authors admit more research must be done on inter-level dependencies and larger networks. Will we see #AI like this making #decisions on DSO level one day? (4)

The presented approach introduces a clever setup of hierarchial multi-agent RL. Agents with different policies each control sections of the grid. Rule based policies safeguard the grid, while low level agents are free to explore the smartest strategies (3)

The Problem:
Power grids are complex & dynamic, especially with a rise in res and storage. Optimizing their structure — like switching lines or buses — is a huge challenge due to the enormous action space involved. Traditional methods hit limits. (2)
