Overall Performance Evaluation of Wind Power and Micro-CAES Hybrid Electricity-Generation System

Abstract:

Article Preview

Micro-CAES can balance fluctuations in supply and demand of electricity. In this technology, air is compressed with a motor/generator using low cost, off-peak or discarded electricity from wind power and stored underground in caverns or pipes. This pressurized air is released then be burned with gas in a combustor. The hot expanding gases drive a micro-turbo expander and run a motor/generator which, in turn, produces electricity during peak demand periods. By considering the factors including economy, reliability, environment protection, and CO2 emission, a fuzzy overall evaluation model for different power supply mode is proposed. The related calculation and optimization are made. Linking with wind power, the overall performance of micro-CAES is best.
