Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.
A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.
Solar and wind are available freely a nd thus appears to be a promising technology to provide reliable power supply in the remote areas and telecom industry of Ethiopia. The project aim generate and provide cost effective electric power to meet the BTS electric load requirement.
Wind energy penetration is the fraction of energy produced by wind compared with the total generation. Wind power's share of worldwide electricity usage in 2021 was almost 7%, up from 3.5% in 2015. There is no generally accepted maximum level of wind penetration.
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
UPS systems are cheaper upfront. But their batteries wear out faster and aren’t designed for daily use. BESS systems are more expensive initially, but they offer long-term savings through energy arbitrage, grid incentives, and durability (especially with lithium iron phosphate batteries). Which One Should You Choose?
For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
They use UPS for surge protection and instant switchovers and BESS to run for 8+ hours during blackouts, powered by solar. The company uses BESS to flatten peak loads and reduce utility bills by 25%, while UPS protects conveyor belts from sudden shutdowns. UPS and BESS both play critical roles, but in different ways.
