What impact does wind energy have on the operation of the electricity system?

Reduction of wind power from a high production level to a lower level or an outage will have a greater impact on the operation of the electricity grid. The intermittent characteristics of wind power determine the random fluctuation characteristics of wind farm output. Once wind power is connected to the power grid, it does not have the stable and dispatchable production characteristics of traditional thermal power plants. For the power grid, the fluctuation in wind power output is more like a negative load disturbance. Therefore, the conventional power supply of the power grid not only needs to provide enough reserves for load fluctuations, but also needs to consider reserving a certain amount of reserve for wind farms to balance the changes in wind farm output when 'a large amount of windElectricity is injected into the network. When wind farm output fluctuates significantly, other power plants in the electricity grid must be dispatched to change their output levels to balance the changes in wind power output. Especially when the load is low, conventional power plant units have been adjusted to reduce their output. If the wind farm's output increases significantly at that time, whether conventional units can produce more power to allow the wind power to carry the load determines the capacity of the grid. capacity to accept wind energy, that is, the peak shaving capacity of conventional units at low load periods is said to be a key condition that limits the ability of the provincial grid to accept wind energy. 'wind power.

Electric power projects are ddivided into four categories: thermal energy projects (including gas generators), electricity transmission and transformation projects, nuclear energy projects and wind energy projects. These four types of projects include different projects, for example:

Thermal power projects include main factory building, chimney, cooling tower, unit installation, l installation of boilers, installation of turbogenerators and booster stations, environmental protection projects, auxiliary projects and other engineering projects.
