In recent years, there has been an increase in the use of renewable energy resources, which led to need for large-scale Energy Storage units electric grid. Currently, Compressed Air (CAES) and Pumped Hydro (PHES) are main commercially available storage technologies. However, these technologies restricted geographically can require fossil fuel streams heat air. Thus, is a develop novel that do n...

ANCILLARY services such as frequency regulation are required for reliable operation of the electric grid. Currently, the same traditional thermal generators that supply bulk power also perform nearly all frequency regulation. Instead, using high power energy storage resources to provide frequency regulation can allow traditional thermal generators to operate more smoothly. However, using energy...

The energy system must be producing close to zero emissions by mid-century to meet stringent climate goals. There are many possible clean energy options, but few are ready or able to replace coal and gas as primary electricity supplies. This paper addresses the issue of whether a viable energy system can be based mostly around solar thermal electricity. It is found that, using thermal storage, ...

Advantages, such as thermal storage improvement, are found when using PCMs (Phase Change Materials) in storage tanks. The inclusion of three different types of materials in a 60 l test tank is studied. Two test methodologies were developed, and four tests were performed following each methodology. A thermal analysis is performed to check the thermal properties of each PCM. The distributions of ...

Solar-driven organic Rankine cycle (ORC) has been drawing increasing attention due to its high potential in energy conversion efficiency. The two core components of thermal application systems of solar energy are solar collectors and thermal energy storage systems, and many studies have been published. ORC also has attracted much attention in recent years due to its potential in reducing consum...

In this paper, a conventional thermal power plant with single stage reheat turbine is taken into consideration. It is equipped with AVR, IEEE type dual input PSS3B and integral controlled AGC loop. A hybrid distributed generation (DG) system consisting of wind turbine generators, aqua electrolyzer, fuel cells, diesel engine generator, flywheel energy storage system and battery energy storage sy...

Chemical incompatibility and low thermal conductivity issues of molten-salt-based thermal energy storage materials can be addressed by using microstructured composites. Using a eutectic mixture of lithium and sodium carbonates as molten salt, magnesium oxide as supporting material, and graphite as thermal conductivity enhancer, the microstructural development, chemical compatibility, thermal st...
