Huatong Yuanhang''s wind-solar complementary system for
Based on the complementarity of wind energy and solar energy, the base station wind-solar complementary power supply system has the advantages of stable power supply,
Since base stations are major consumers of cellular networks energy with significant contribution to operational expenditures, powering base stations sites using the energy of wind, sun, fuel cells or a combination gain mobile operators' attention.
It is shown that mobile network operators express significant interest for powering remote base stations using renewable energy sources. This is because a significant percentage of remote base station sites on the global level are still diesel powered due to lack of connections to the electricity grid.
Wind power has no effect on base load. However, since base load providers can not be ramped down, if wind turbines produce power when there is no or little peak load, the extra electricity has to be dumped (e.g., into the ground) or the wind turbines turned off (”curtailment”). How does wind power affect peak load?
The preferred source that wind power may replace on the grid is hydro power, which is already carbon dioxide free. If a conventional source is replaced, it may simply be ramped down or switched from generation to standby, in which mode it still burns fuel and emits carbon dioxide.
