IntroductionDuring three-phase faults in power grids, existing low-voltage ride-through (LVRT) strategies are often constrained by the current withstand capability of converters, resulting in insufficient voltage support. In addition, the widely used virtual impedance method involves complex calculations and difficult parameter selection under complex grid conditions.MethodsTo address these issue…

The complementary utilization of oxyhydrogen and bio-isopropanol in carbon-neutral fuel engines can effectively enhance power output and combustion stability. However, oxyhydrogen blended combustion results in an increase in NOx emissions. To address this issue, this study explores the synergistic mechanisms of lean-burn coupled with exhaust gas recirculation (EGR) in an engine featuring oxyhydro…

With the high penetration of renewable energy, electricity spot market prices exhibit significant temporal volatility, exposing photovoltaic (PV) power plants to the risk of “price cannibalization” during their peak generation periods. The traditional design paradigm, which relies on the single objective of “maximizing annual power generation,” neglects the time value of electricity and is no lon…

To address the operational challenges arising from the large-scale integration of distributed photovoltaic (PV) generation in distribution power network (DPN), this paper investigates an optimal configuration strategy and enhanced performance evaluation of soft normally open point (SNOP) in DPN. First, a bi-level optimization model is developed to jointly consider the investment cost and annual o…

Multi-terminal flexible DC transmission is the primary means for transmitting renewable energy from deserts, gobi, and southeastern Tibetan regions. The online insertion and bypass of high- or low-voltage valves in modular multilevel converters (MMCs) is a unique issue for ultra-high voltage DC (UHVDC) systems, which does not exist in conventional HVDC systems. HVDC systems have only one valve pe…

IntroductionAs clean energy penetration grows, short-term coordination of pumped storage hydropower plants (PSHPs), wind power and photovoltaic (PV) generation is increasingly important for secure and economical dispatch under renewable variability.MethodsThis study proposes a short-term forecasting-based scheduling and benefit allocation method for a PSHP-wind-PV complementary system. A hierarch…

Weak grids face critical challenges of insufficient inertia support and phase-locked loop instability in wind power integration. Traditional deloading strategies rely on inflexible look-up tables, while virtual synchronous generator (VSG) control suffers from coupled droop and damping parameters, causing severe DC bus voltage fluctuations. To address these issues, this paper proposes a novel delo…

The Mexican government just unveiled a prototype for a new homegrown, ultra-affordable EV. Mexican President Claudia Sheinbaum drove the prototype, dubbed the Olinia Uno, onto a stage Sunday during an unveiling event inside a Mexican Air Force hangar near Mexico City. The Olinia Uno is a planned six-passenger car that can travel up to 125 kilometers (77 miles) on a single charge. It is expected t…

For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits on how much force it can exert. Through new research published in Nature, a team led by Dong Wu at Anhui University, […]

GOLDEN, Colorado – Scientists are engaged in research with an eye toward transforming the cold climes of Mars into a far more humane place for Earthlings in the future. One notion proposed is dispersion of an aerosol meant to motivate the warming of Mars’s atmosphere. The idea is projected to be a first step toward […]

USC Viterbi researchers have proved that fracture geometry can suppress unstable flow patterns and enhance fluid mixing, with implications for groundwater remediation, carbon storage, hydrogen storage and energy production. The post A New Way to Control How Fluids Move Through Rock appeared first on USC Viterbi | School of Engineering .

The Problem: Feature Velocity Was Creating Structural Debt The system originally started as a simple feature delivery backend: A Django API powering agricultural insights Celery workers handling asynchronous processing Independent endpoints for each new capability A growing set of Earth Observation computations (NDVI, NDWI, etc.) At first, it worked. But as more features were added, a pattern eme…

From the ashes of clean tech 1.0 to scaling automotive-grade silicon anodes in Moses Lake, Sila co-founder and CEO Gene Berdichevsky shares why patience, market forces, and material science are the true keys to the energy transition. Read More

Industry 4.0 gets talked about like it is one big thing. In practice, it is a data pipeline. Sensors generate readings. Gateways process them. Cloud platforms store and analyze them. Dashboards surface them. Automation acts on them. If you are building the software layer for any of this, what matters is understanding how data flows through each stage because that is where the architecture decisio…
