(PDF) Optimization and improvement method for complementary
This project will fully consider the complementary relationship between photovoltaic, wind and energy storage, and optimize the charging and discharging strategy of energy
Notwithstanding these limitations, the result of this work clearly highlights the added value of using wind and solar PV complementarity and electricity criteria as a planning strategy for new VRE capacity deployment aiming to reduce the power flexibility needs, namely, the use of expensive energy storage systems.
In, a considerable complementarity between the wind and solar power production in Portugal was also identified, i.e., when the solar PV output is maximum, wind generation tends to exhibit the minimum values (daytime), and vice versa.
This study provided the first spatially comprehensive analysis of solar and Wind energy Complementarity on a global scale. In addition, it showed which regions of the world have a greater degree of Complementarity between Wind and solar energy to reduce energy storage requirements.
The review of the techniques that have been used to evaluate the complementarity of solar and wind energy systems shows that traditional statistical methods are mostly applied to assess complementarity of the resources, such as correlation coefficient, variance, standard deviation, percentile ranking, and mean absolute error.
