Do you think it is a technical problem that wind power is limited by more than 20% of the power grid

Introduction Do you think it is a technical problem that wind power is limited by more than 20% of the power grid's output? The rapid development of wind turbines has already had a great impact on the power grid. Low voltage ride through has been almost transformed,

Do you think it is a technical problem that wind power is limited by more than 20% of the power grid

Wind turbines have developed too fast and have had a great impact on the power grid. The low voltage ride through has been almost transformed. After the avc transformation is completed, the response of the power grid will be improved. I think the large-scale power rationing you mentioned is not a deliberate restriction by the power grid. It depends on the capacity of the local wind farm’s grid connection point. Your grid connection point is 220kV or 110kV, and the capacity cannot exceed 100, while the wind farms in Northeast China and Inner Mongolia The large one can reach 400,000, and the medium one can reach 200,000. The electricity consumption in Northeast and Inner Mongolia is low. The power grid was not that big when it was originally designed. However, the trend of new energy development is national policy. The power grid can dispatch wind farms, but it must comply with the national policies. In response to the development trend, wind farms were built in large numbers, but the power grid was not followed or transformed in advance, resulting in widespread power rationing. At present, if the wind farm is built near a 500kV main station, there will be almost no power rationing, that is, it will be almost the Spring Festival, because you can't affect it, and your full or zero output will have almost no impact on its voltage. I suggest you report it to your superiors. The location of the substation is very important. Avoid the ends of those lines and be close to the main station! Also, smart grids will come, and bread will come

Is 1.5 MW wind power considered breeze power?

1. Development of power generation plan: Since the output power of wind power is difficult to predict accurately, Therefore, in the day-ahead, real-time and dispatch stages of microgrids, the uncertainty of wind power needs to be considered and processed to ensure the balance of supply and demand in microgrids. For example, methods based on probabilistic prediction models can be used to estimate wind power generation and formulate corresponding dispatch plans.

2. Energy dispatch strategy: The uncertainty of wind power will also affect the energy dispatch strategy of microgrid. Due to the uncertainty of wind power output power, it will cause changes in the operation of other power generation equipment in the microgrid, thereby affecting the load satisfaction of the microgrid. Therefore, it is necessary to develop reasonable energy dispatch strategies for the uncertainty of wind power to maximize the power generation potential of wind power while ensuring the balance between supply and demand in microgrids.

3. Power quality and stability: The uncertainty of wind power will also affect the power quality and stability of microgrids. When the power generation of wind power suddenly changes, it will cause the voltage, frequency and other power parameters of the microgrid to fluctuate, thus affecting the power supply quality and stability of the microgrid. In order to solve this problem, technical means such as power electronic devices and energy storage equipment can be used to adjust the power parameters of the microgrid to ensure the stable operation of the microgrid.

4. Economic analysis: The economics of microgrids are also affected by the uncertainty of wind power. Due to the uncertainty of wind power, additional costs will be incurred in the dispatch of non-wind power equipment in microgrids. Therefore, in the planning and design of microgrids, the uncertainty of wind power needs to be fully considered and analyzed to maximize the economy of microgrids.

1.5 megawatts (MW) of wind power is not breeze power. Breeze power generation usually refers to power generation when the wind speed is low. Generally speaking, breeze power generation is suitable for environments with wind speeds between 2-7 meters/second.territory. This type of wind turbine is usually less powerful and suitable for operation in low wind speed conditions. And 1.5 MW wind power refers to a wind turbine with a rated power of 1.5 MW, which means it can generate electricity at 1.5 MW per hour. This power level is relatively large and generally suitable for medium to high wind speeds. Therefore, 1.5 MW wind power is more suitable for generating electricity under higher wind speed conditions and can provide larger power output. To sum up, 1.5 MW of wind power is power generation under medium to high wind speed conditions, not light wind power generation.
