The impact of wind power variability on the least-cost dispatch of units in the electricity generation system

摘要: This thesis investigates the dynamics of electricity generation systems that involve high levels wind power. Methods to account for power variability in electricity-dispatch models are explored, and impact on optimal output units, so as meet system load with lowest possible cost (economic dispatch), is analyzed several systems, both regional European cases. Systems lack active variation management, well management through storage, charging plug-in hybrid electric vehicles, trade hydropower-rich Nordic countries, investigated. The work considers which supplies between 20 % 40 demand an annual basis. From this thesis, it concluded inclusion cycling costs can have significant impacts capacity factor individual units obtained from modeling dispatch penetration (i.e., relative electricity). Whether need be included analysis depends level research question being posed, relationship running thermal system. Furthermore, shown a wind-thermal system, corresponds about 20% electricity, variations net (here defined reduced by each hour) follow diurnal pattern, shifting day night reduces competition poor properties. However, 40% power, ability store or shift over longer time periods days) confers advantages compared night, owing altered pattern load. Finally, shows role electricity-generation context relies heavily balance investments interconnector capacity. If planned interconnections Norway rest Europe established, export likely countries Germany UK, whereby would play central redistributing high-wind events peak-load events.
