What factors influence the total cost of generating electricity from grid-connected wind turbines?

1. Initial investment in unit installation

2. The unit failure rate. Many domestic manufacturers are now engaged in a price war. The cost of electricity per unit of wind turbine has fallen repeatedly. but the quality of the units often does not guarantee, many manufacturers do Tai Chi when they shout about the low failure rate. Failure rate does not mean how long a component of the unit fails once, but it is based on the proportion of time. that the unit cannot produce electricity due to the unit breaking down for the entire time it can produce electricity, so manufacturers who offer good after-sales service have an advantage . Once the unit breaks down, I will shut down and continue producing electricity. as usual after repair. However, some manufacturers do not do a good job of after-sales servicee. Repairing the unit after a breakdown takes a long time. In this case, the failure rate of an easily broken unit is high. smaller than that of a good quality unit, but its maintenance cost is more expensive than that of a good quality unit. Therefore, these two points must be balanced when considering the failure rate.

3. Power rationing. Many wind farms with good wind resources are located in remote areas, especially in Xinjiang. Qinghai and Inner Mongolia are the most affected wind areas. Due to insufficient construction of the local power grid, many wind turbines have to shut down and limit power in windy weather. In this case, the energy production of the wind turbines is reduced, but on a daily basis. maintenance still needs to be carried out, which ultimately leads to an increase in electricity generation costs.

4. Selection of energy storage devices. The battery cannot be charged and discharged frequently, which will greatly reduce battery life. Now battery technology cannot be said to be relatively mature, but battery usage should always be minimized during the power generation process.
