Peer-to-Peer Energy Markets With Uniform Pricing: A Dynamic Operating Envelope Approach
The recent widespread adoption of rooftop solar backed by battery storage is enabling energy customers to both produce and consume electricity (i.e., prosumers of electricity). To facilitate prosumer participation in the electric grid, new market mechanisms are required. In this paper, we design peer-to-peer energy markets where prosumers trade their excess energy with peers to gain profit while satisfying the overall balance in electricity supply and demand.

Long-term electricity demand forecasting is essential for grid and operations planning, as well as for the analysis and planning of energy transition strategies.

They avoid heat as an intermediate step and are therefore much more efficient. This can significantly reduce the demand for primary energy in the future, which can then be fully covered by the expansion of renewable energies. Entropy and the maximum possible combustion temperature can be used to understand why combustion is so inefficient.

I dreamt last night that I was in Glasgow for a concert and a massive power failure occurred. There was no electricity and all electronics were fried - radio, phones, internet, nothing working except some very old cars with no electronic systems.
We heard rumours that either the Earth had been hit by an EMP pulse from a cosmic event, or maybe this was more local and was caused by a weapon of some kind.
Police were out on horseback telling us to stay calm but had no info. /1

I don’t know, asshole, was 1947 worth it? Was close to 80 years of settler colonialism and apartheid worth it? Is the current genocide of the Palestinian people being committed by israel worth it? https://ravenation.club/@welkin7/114652095075122736

Poland pilots solar arrays near major highway
Poland has installed solar arrays along the S5 expressway as part of a project to cut infrastructure operating costs. Surplus electricity will feed the grid or supply electric vehicle charging stations.

The world's data centers already consume three times as much electricity as Dutch national consumption. And this is expected to grow to 8 times within five years.

Trump’s newly signed tax and spending law, eviscerated Biden-era incentives for clean technologies such as wind and solar power.
Now Democrats aim to flip the usual partisan energy debate
by portraying Republicans as the party of electricity shortages and rising prices.
Their targets would include the moderate Republicans who spent months urging Congress to preserve the Biden tax breaks because of their projected economic gains for GOP-held districts

An advanced reliability reserve incentivizes flexibility investments while safeguarding the electricity market
To ensure security of supply in the power sector, many countries are already using or discussing the introduction of capacity mechanisms. Two main types of such mechanisms include capacity markets and capacity reserves. Simultaneously, the expansion of variable renewable energy sources increases the need for power sector flexibility, for which there are promising yet often under-utilized options on the demand side. In this paper, we analyze how a centralized capacity market and an advanced reli…

EU would require €241-286 billion investment to keep its nuclear power capacity roughly at today's level, draft shows. It would increase from 97 now to 109 GW by 2050; that's 12%, sharply reducing its share of growing overall electricity demand.

The most recent heatwave in Brussels (from 30 June to 2 July) led to a 15% increase in electricity consumption, according to the region's DSO.
Assuming that 🍦 production is only a marginal component of this, demineralisation and building insulation measures should be at the forefront of action.

Arbitrage Tactics in the Local Markets via Hierarchical Multi-agent Reinforcement Learning
Strategic bidding tactics employed by prosumers in local markets, including the Local Electricity Market (LEM) and Local Flexibility Market (LFM), have attracted significant attention due to their potential to enhance economic benefits for market participants through optimized energy management and bidding. While existing research has explored strategic bidding in a single market with multi-agent reinforcement learning (MARL) algorithms, arbitrage opportunities across local markets remain unexp…

It is just INSANE that the GOP is going to 🆘 tax new solar and wind capacity,
as well as a whole bunch of other terrible energy policies in the BBB,
when electricity prices have risen 20% since start of 2022,
and the grid is ever more fragile.
Prepare for a lot of rolling blackouts.

Optimization and Control Technologies for Renewable-Dominated Hydrogen-Blended Integrated Gas-Electricity System: A Review
The growing coupling among electricity, gas, and hydrogen systems is driven by green hydrogen blending into existing natural gas pipelines, paving the way toward a renewable-dominated energy future. However, the integration poses significant challenges, particularly ensuring efficient and safe operation under varying hydrogen penetration and infrastructure adaptability. This paper reviews progress in optimization and control technologies for hydrogen-blended integrated gas-electricity system. F…
