WIDER Working Paper No. 2013/067 Characterizing wind power resource reliability in southern Africa

چکیده
Producing electricity from wind is attractive because it provides a clean, low-maintenance power supply. However, wind resource is intermittent on various time scales, thus introducing variability in power output that is difficult for electric grid planning. In the following study, wind resource is characterized using metrics that highlight these intermittency issues, therefore identifying areas of high and low wind power reliability in southern Africa at different time scales. After developing a wind speed profile, these metrics are applied at various heights in order to assess the added benefit of raising the wind turbine hub. Furthermore, since the interconnection of wind farms can aid in reducing the overall intermittency, the value of interconnecting near-by sites is mapped using three distinct methods. Of the countries in this region, the Republic of South Africa has shown the most .../

WIDER Working Paper No. 2013/071 The impact of climate change on wind and solar resources in southern Africa
Climate change is an issue that requires global attention and co-operation. As climate science develops an understanding of changes to the future climate state, policy makers and engineering project planners beg to know what claims can be made on the subject with a reasonable level of confidence. A common and popular mitigation strategy for reducing emissions is to build away from carbon intens...
متن کاملReliability Assessment of Power Generation Systems in Presence of Wind Farms Using Fuzzy Logic Method
A wind farm is a collection of wind turbines built in an area to provide electricity. Wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. In this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in HL1 level is proposed. In proposed procedure, application of Fuzzy – Markov f...
متن کاملRisk Analysis and Economic Load Dispatch Evaluation of Network with High Wind Power Penetration
This study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. Wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. However due to unpredictable nature...
متن کاملCharacterization of the wind power resource in Europe and its intermittency*
Wind power is assessed over Europe, with a special care given to the quantification of intermittency. Using the methodology developed in Gunturu and Schlosser [1], the MERRA boundary flux data was used to compute wind power density profiles over Europe. Besides of the analysis of capacity factor, other metrics have been designed to further quantify the availability and reliability of this resou...
