The Authors consider that as a mid-term storage technology (from some hours to some days), small/medium size CAES systems (1-10 MW) might be efficiently and profitably used for off-grid and self-consumption applications as well as for the provision of ancillary services on the lower grid levels....

The impact on a utility incorporating wind turbine generation due to wind speed sampling frequency, wind turbine performance model, and wind speed forecasting accuracy is examined. The utility analyzed in the study was the Los Angeles Department of Water and Power and the wind turbine assumed...

In this Appendix, the study framework and evaluation for economic and technical factors are explained. This material documents the analysis performed for Section 4.8 of the EIS. Coupled with the environmental analysis, the evaluation factors described below will be used to judge the relative...

Battelle, Pacific Northwest Laboratory (PNL) is conducting a program to help assess impacts of energy-related developments through the year 2025 in six northwestern states--Washington, Oregon, Idaho, Montana, Wyoming and Alaska. ELSA (Electric Power Supply Analysis Model), one component of this...

High temperature fuel cells (MCFCs and SOFCs) can operate at atmospheric or pressurised conditions. In both cases, system performance can be significantly improved when the fuel cells are integrated with proper devices, which are designed to provide the necessary air inlet conditions and to...

The Two-Element In Series (TEIS) and Two-Zone models have been used successfully for over twenty years to model test data for radial flow compressors and pumps. The models can also be used to predict the performance of new machines provided that the model inputs can be accurately specified....

The Two Element in Series (TEIS) and Two Zone models stand out as powerful tools that enable deeper understanding of compressor stage designs after they have been tested. The insights gained from these investigations have aided in improving new stage designs. Up to now, it has only been possible...

Tidal power generation with reciprocating turbines in a simple system is investigated on a performance simulation in order to enlarge the capability of practical use of tidal power with extra-low head and time-varying energy density characteristics. Four reciprocating turbines, which are two...
