Chronological simulation study of wind power consumption with consideration of secure unit commitment constraints

Large scale wind consumption capability is influenced by generation mix, load characteristics, transmission network deliverability and even wind power characteristics. This paper performed chronological simulation with consideration of secure unit commitment constraints to study wind power consumption of a test system in North China. Case study indicates that the most challenging time period of wind power consumption is winter night especially during the Spring Festival when the load is very low and generation output cannot be decreased to meet heating needs.
