Small-sized communication base station wind and solar complementarity
This paper describes the design of an off-grid wind-solar complementary power generation system of a 1500m high mountain weather station in Yunhe County, Lishui City.
Typically, wind power and photovoltaic stations are situated at different locations, necessitating the study and analysis of wind speed-radiation complementarity across various regions. This study focuses on wind power stations and photovoltaic stations in Qinghai and Gansu provinces to explore their complementarity.
The joint operation of wind, solar, water, and thermal power based on pumped storage power stations is not only a supplement and improvement to traditional energy systems but also a crucial step towards a cleaner, more efficient, and more sustainable energy future.
Utilizing the clustering outcomes, we computed the complementary coefficient R between the wind speed of wind power stations and the radiation of photovoltaic stations, resulting in the following complementary coefficient matrix (Fig. 17.).
Previous studies have primarily used the Pearson correlation coefficient (CC) and similar metrics to evaluate the complementarity of wind and solar resources. For instance, Che et al. directly calculated Pearson CC to analyze the complementarity between wind and solar power and between wind and hydropower.
