Research on energy storage capacity planning in multi-energy complementary form of park

As a flexible resource, energy storage plays a role in promoting the absorption of new energy and the safe and stable operation of power system. However, limited by the cost of energy storage investment, it is difficult to rely on large-scale energy storage to meet the flexibility requirements of the system. In order to solve the problem of electric/thermal energy storage configuration of integrated energy, a method of electric/thermal energy storage configuration of regional integrated energy system with wind power access was proposed. Firstly, the dynamic neural network prediction model for wind power prediction is constructed to effectively predict the wind farm output in the regional integrated energy system. Then, the charging and discharging behavior of electric/thermal energy storage in regional integrated energy system is analyzed, the relationship between electric and thermal storage and regional wind farm power is established, and the electric/thermal coupling relationship is considered to form a joint optimal configuration model of electric/thermal energy storage.
