A review on the complementarity between grid-connected solar
• The paper proposes an ideal complementarity analysis of wind and solar sources. • Combined wind and solar generation results in smoother power supply in many places.
Han et al. have proposed a complementarity evaluation method for wind, solar, and hydropower by examining independent and combined power generation fluctuation. Hydropower is the primary source, while wind and solar participation are changed in each scenario to improve power system operation.
The combined use of wind and solar power is crucial for large-scale grid integration. Review of state-of-the-art approaches in the literature survey covers 41 papers. The paper proposes an ideal complementarity analysis of wind and solar sources. Combined wind and solar generation results in smoother power supply in many places.
For example, according to Nascimento et al., wind resources complement solar energy by 40 %–50 % in the Brazilian Northeast along the coastline, reaching up to 60 % in Rio Grande do Norte state. Concerning other regions, the complementarity levels reach 40 % in the South, Southeast, and the remainder of the Northeast .
Combined wind and solar generation results in smoother power supply in many places. Renewable energy has been used as an alternative solution to fossil fuels aiming to supply the increasing energy demand while reducing greenhouse gas emissions.
