Heat, a major source for electricity, can be obtained from either green energy sources such as solar heat and geothermal energy, or raw energy sources (e.g., petroleum, natural gas, and coal). According to a report from Lawrence Livermore National Laboratory, out of about 98.3 Quads (1 ...
But despite the current distaste for nuclear, it has a critical advantage over other clean sources. It generates electricity that doesn’t fluctuate depending on the time or day or weather conditions, so it can help to balance out intermittent wind and solar generation, without requiring vast amo...
Considering the uncertain component outrage induced by the hurricane extreme weather event and stochastic renewable energy sources (RESs) output, a two-stage risk dispatch model for the CEHS can be proposed to hedge against the risk brought by the uncertain.The hurricane-induced distribution line out...
