Impact of Decentralized Wind Generation in Power Systems Reliability. Variable Speed Wind Turbines

摘要

Electricity supply is challenged from deregulation and third party access to the network. In consequence of this, dispersed generation from Independent Power Producers based on co-generation units, renewable ener- gies or other conventional sources increase in all countries. Wind Energy Converters is one of the different technologies in use and development. Most utility-scale wind turbines are operated at constant speed, but there is an increasing interest in variable speed ones. In this paper, a variable speed, stall regulated wind turbine has been simulated, evaluated and compared to a fixed speed wind turbine to study the impact in power sy- stems reliability, on the basis of classic indices and risk base capacity benefit factors, as adequacy indices.
