David Wallace is an assistant clinical professor of electrical engineering at Mississippi State University. The geomagnetic storm that began on May 10, 2024, generated stunning aurora borealis, more commonly known as the northern lights, that could be seen as far south as Mexico. They also generated headaches for farmers whose GPS-guided tractors were idled in the middle of planting season. Geomagnetic storms occur when a large bubble of superheated gas called plasma is ejected from the surface of the Sun and hits the Earth. This bubble is known as a coronal mass…

Author : Martin Craig, JCE Energy 14 May 2024 In the world of energy production, power is not just a component; it’s the cornerstone that propels every facet of the industry forward. From the depths of drilling and extraction to the complexities of processing and distribution, it is the uninterrupted flow of power that ensures operations run smoothly and efficiently. A disruption in this flow doesn’t merely pause operations; it halts the entire lifecycle of energy production and its revenue streams. Image: JCE Energy (Click here to view article in…

A group of scientists in Thailand has outlined a new approach to avoid oversizing and overvoltage in energy markets applying volt-watt droop curtailment strategies. The novel methodology leads to a reduction in a PV system’s net present value but also increases its levelized cost of energy. May 14, 2024 Emiliano Bellini Researchers from King Mongkut’s University of Technology North Bangkok in Thailand have proposed a new methodology to conduct techno-economic assessments of distributed PV systems considering overvoltage-induced curtailment. The scientists stressed that, unlike previous methods for PV system sizing, the…

A few factors can make going solar in San Diego worth the investment. Located in southern California, the city receives exceptionally high amounts of sunlight, a major benefit of solar energy. The city also has significantly high electricity prices, which solar panels can help offset. Combined with the state’s solar-friendly policies and incentives, these factors make San Diego a prime location to install a solar power system. The same is true for other cities in California, including the larger cities of Los Angeles and San Francisco or smaller towns like…
