The provision of renewable electricity is the foundation for a sustainable future. To achieve the goal of sustainable renewable energy, Battery Energy Storage Systems (BESS) could play a key role to counteract the intermittency of solar and wind generation power. In order to aid the system, the BESS can simply charge at low wholesale prices and discharge during high prices, which is also called energy arbitrage.

“Stimulating flexible demand by 8.3% benefits solar producers 31 per cent more than if new demand follows traditional patterns by increasing capture price for solar producers by 9.9 per cent”

How Batteries, Not Natural Gas, Can Power the Data Center Boom
Tech companies are turning to natural gas to help power the growing number of A.I. data centers in the U.S. Jigar Shah, a former Energy Department official, explains how installing batteries instead can help balance the grid, lower electricity bills, and support renewable energy.

Australia's renewable energy boom is coming—and it could solve a surprising problem.
Over the next decade, we'll build more clean energy infrastructure than the past 30 years combined. But where will thousands of construction workers live in regional towns already facing housing shortages?
A new RE-Alliance report shows worker accommodation can become lasting community assets: refurbished aged-care homes, workforce villages transformed into suburbs.

Solar and Wind Power Forecasting: A Comparative Review of LSTM, Random Forest, and XGBoost Models
Rising global energy demand from population growth raises concerns about the sustainability of fossil fuels. Consequently, the energy sector has increasingly transitioned to renewable energy sources like solar and wind, which are naturally abundant. However, the periodic and unpredictable nature of these resources pose significant challenges for power system reliability. Accurate forecasting is essential to ensure grid stability and optimize energy management. But due to the high variability in…

Power Reserve Capacity from Virtual Power Plants with Reliability and Cost Guarantees
The growing penetration of renewable energy sources is expected to drive higher demand for power reserve ancillary services (AS). One solution is to increase the supply by integrating distributed energy resources (DERs) into the AS market through virtual power plants (VPPs). Several methods have been developed to assess the potential of VPPs to provide services. However, the existing approaches fail to account for AS products' requirements (reliability and technical specifications) and to provi…

Toward a Robust Biomimetic Hybrid Battery: Bridging Biology, Electrochemistry and Data-Driven Control
Electric vehicles and renewable energy systems need batteries that charge quickly, last many years and still store a lot of energy, but current chemistries struggle to deliver all three. Inspired by electric fish that deliver bursts of current and birds that sleep with half their brains, we propose a hybrid battery concept called SwiftPulse. It combines sodium-ion cells that provide energy with niobium-oxide cells that accept high-power pulses. A pulse-based charger and a battery-management str…

Uncertainty-Aware Flexibility of Buildings: From Quantification to Provision
Buildings represent a promising flexibility source to support the integration of renewable energy sources, as they may shift their heating energy consumption over time without impacting users' comfort. However, a building's predicted flexibility potential is based on uncertain ambient weather forecasts and a typically inaccurate building thermal model. Hence, this paper presents an uncertainty-aware flexibility quantifier using a chance-constrained formulation. Because such a quantifier may be …

Multi-Loop Design of Virtual Synchronous Machine Control for DFIG-Based Wind Farms
The displacement of synchronous generators by converter-interfaced renewable energy sources obliges wind farms to provide inertia, damping, and voltage support, above all in increasingly weak grid conditions. This paper presents a co-ordinated frequency-domain methodology for tuning all control layers of doubly-fed induction generators (DFIGs) within a wind farm operated as a Virtual Synchronous Machine (VSM). Starting from a full small-signal linearisation that preserves loop-to-loop and machi…
