UrduAbstract A high-quality solar power forecasting system that strictly adheres to grid regulations is valuable for system operators to formulate strategies for power system scheduling. Some grid operators, therefore, enact penalty schemes for the forecasts submitted by photovoltaic (PV) plant…

Hydrogen Technologies Take Leading Role Toward Net Zero
Achieving Net Zero energy, where the total amount of energy used is equal to the amount of renewable energy created, is closer than ever before, and hydrogen technologies will play an important role in achieving that goal, but needs and gaps need to be addressed before a true hydrogen-powered future can take form. There are many opportunities in the global public and private sectors for research, development, and deployment collaboration.
Powering Navigational Buoys With Help of Ocean Waves
Traditionally used energy harvesting technologies, like photovoltaic panels or wind turbines, suffer from several limitations. In the absence of daylight and wind, neither of the two can supply any power. In the case of ocean buoys, a potential solution is omnipresent: wave energy. Abundant, predictable, and consistent, the ocean’s waves can be used to power navigation buoys. Researchers have developed sphere-based triboelectric nanogenerators that can be incorporated directly into navigational buoys to provide electricity from ocean waves.
Indoor Lighting Creates Power for Rechargeable Devices, Sensors
As more devices require recharging their batteries, researchers are looking to ambient lighting as a potential source of generating small amounts of power for indoor devices. The researchers used one lighting source, a white LED akin to normal brightness for indoor lights, to test three different modules — a gallium indium phosphide semiconductor, a gallium arsenide semiconductor, and a silicon semiconductor. The light source peaked in intensity on the shorter wavelengths of light.
Measuring Photovoltaic Performance Indoors
As photovoltaic technology continues to progress, PV devices’ applications in harvesting energy from indoor ambient light have become more realistic. Some combinations of PV material and light source can be more efficient in converting power than the same material under solar illumination, and a better understanding of these relationships is needed to fully characterize the behavior of solar cells under very low illumination conditions.
Tweaks Behind the Rebirth of Nearly Discarded Organic Solar Technologies
A minuscule, counterintuitive chemical tweak is advancing an organic solar technology that was believed unviable.
