Comments Off on New smart grid solution heals itself amid central grid outages

Renewable energy may offer emissions-free electricity , but it isn’t always easy for electrical grids to integrate that energy. Dutch company Alfen is launching their answer to the dilemma. The Cellular Smart Grid Platform (CSGriP) allows a central grid to be divided into smaller cells that can operate independently, if necessary, and even self-heal . CSGriP provides energy from sources like biogas , solar power , or wind power for local consumers. It includes “a 0.5 megawatt energy storage system and complex algorithm used for local energy management.” Should the central grid go out, local cells would take over to restore power for local customers. According to Alfen, “Once the grid balance within a cell is restored, it automatically reconnects to other cells, and, as such, quickly rebuilds the larger power grid” to reduce the duration of central grid outages. Related: INFOGRAPHIC: How a smart electric grid could reduce emissions by 58 percent in the US Alfen energy storage specialist Evert Raaijen said in a statement, “Unique about this solution is that the local cells are intrinsically stable through self-adjustment of supply and demand based on the frequency of the electricity grid. This makes the grid truly self-healing in cases of central grid outages. The self-healing mechanism based on frequencies sets it apart from many IT-related smart grids that require relatively vulnerable data and ICT connections for balancing local grids.” In developed countries, the point of the platform is to decentralize the grid and make it more ready for renewables. But the platform could also be deployed in developing countries that still need to be electrified, allowing them to avoid constructing central grids obtaining power from large fossil fuel -burning plants in favor of these local cells with storage systems for renewable sources. Alfen has worked in countries from the United Kingdom to the Czech Republic to Nigeria, on projects for electric vehicle charging , transformer substations, energy storage, smart grids, and grid automation. They are currently field testing CSGriP at the Application Center for Renewable Resources in Lelystad, the Netherlands . + Alfen Via Alfen Images via Alfen on Twitter ( 1 , 2 )

Archaeologists find 2,150-year-old Petra monument ‘hiding in plain sight’

Comments Off on Archaeologists find 2,150-year-old Petra monument ‘hiding in plain sight’

The ancient city of Petra in Jordan is known for its fascinating ruins built into surrounding rocky cliffs, and now archaeologists have made an exciting new discovery. Using satellite images , they recently discovered a massive subterranean monument that remained hidden for years. The monument is about the length and double the width of an Olympic swimming pool . The archaeologists used satellite imagery to find the platform, which is 184 feet by 161 feet. An interior platform had columns along one end and a huge staircase. Based on pottery studies, the researchers think the platform could be at least 2,150 years old . Related: Family accidentally discovers “extraordinarily well-preserved” Roman villa in England Given the colossal size, it’s surprising no one has yet discovered the monument, but the researchers said it was difficult to get to and “hidden.”Even though the monument is close to the center of Petra – just around half a mile south, prior surveys didn’t find it. The paper the archaeologists published is titled ” Hiding in Plain Sight .” Co-author of the paper Christopher Tuttle told National Geographic, “I’m sure that over the course of two centuries of research [in Petra], someone had to know [this site] was there, but it’s never been systematically studied or written up. I’ve worked in Petra for 20 years, and I knew that something was there, but it’s certainly legitimate to call this a discovery.” Tuttle told The Guardian the platform could have been used for “some kind of massive display function.” Throughout the rest of Petra, there are several shrines and sites used for “various cultic displays or political activities.” However, one reason the new monument stands apart is because the massive staircase doesn’t face Petra’s city center. “We don’t understand what the purpose [of visible shrines], because the Nabateans didn’t leave any written documents to tell us,” Tuttle said. “But I find it interesting that such a monumental feature doesn’t have a visible relationship to the city.” As of now the researchers don’t have a plan for excavation , but they hope to work at the site at some point.
