Abstract:

As the global energy crisis approaches, the development and utilization of new energy has become an important field for people to explore today. Solar energy, wind power, hydrogen energy, etc. have become the important representatives of the new energy development by their advantages of clean and pollution-free. Among them, wind power storage is an important part of the current power system, which can be connected to the grid system to provide important help to meet the power supply needs of people in a region, and has a very bright development prospect. However, the wind power generation is seriously affected by climate, and its power supply output has randomness and instability. Therefore, energy storage devices need to be configured in wind power system to realize the energy storage capacity optimization, so as to ensure the balance and stability of power supply in the grid. Based on the development status of wind power system, this paper analyzes its hybrid energy storage capacity optimization model, and proposes a collaborative optimal configuration scheme considering different conditions for hybrid energy storage capacity of wind power system, which can provide a reference for effectively improving the operation efficiency and quality of the grid with the wind power integration.

Key words: wind power, hybrid energy storage, distribution network risk, energy storage capacity optimization
