Does solar-wind complementarity exist in continental China?
In their assessment of solar-wind complementarity in continental China, and using the Pearson correlation coefficient, Ren et al. found similar results to ours regarding the spatial distribution of synergy between these two VRES on a daily scale.
Why do we need a spatial analysis of solar and wind energy complementarity?
A further problem reducing the spatial coverage of studies, is a lack of uniform method applied in available studies. Therefore, this work contributes to the existing body of knowledge by providing a first spatially comprehensive analysis of solar and wind energy complementarity on a global scale.
What is the complementarity metric for solar-wind hybrid generation?
Besides using Kendall's tau correlation as the complementarity metric, this research is based on a pair of indicators (a: solar share, and b: sizing coefficient) derived from a concept of sizing of stand-alone solar-wind hybrid generation to minimize fluctuations of energy production, consequently reducing the required energy storage capacity.
Is Kendall's tau a theoretical limit for solar-wind complementarity?
Among the primary findings of this paper, we can mention that Kendall's Tau ranges between –0.75 and 0.75, are in line with previous research for specific regions, and might work for a theoretical limit in applied research benefiting from solar-wind complementarity.

What is the power system in Cape Town?
Cape Town's power system is made up of a grid that distributes electricity across the city. Electricity is crucial to the functioning of Cape Town, powering homes, businesses, and infrastructure. The sources of electricity in Cape Town include coal, natural gas, and renewable energy options.
What is the most important source of electricity in Cape Town?
Coal is the most significant source of electricity in Cape Town, accounting for a significant portion of the city's energy mix. However, there is a growing emphasis on diversifying the energy sources and increasing the share of renewable energy in the city's power generation.
What type of energy does Cape Town use?
Cape Town relies on a mix of energy sources for its electricity generation. The city's power plants use coal, natural gas, and renewable energy sources such as wind and solar power. Coal is the most significant source of electricity in Cape Town, accounting for a significant portion of the city's energy mix.
What is the power grid in Cape Town?
Cape Town's power grid is a complex network of transmission lines and substations that distribute electricity across the city. The grid is divided into different zones or areas that receive power from specific substations. These substations receive electricity from the transmission lines, which are connected to power plants.
