The application discloses a wind farm unit reconstruction and
energy storage configuration collaborative
planning method and
system, and relates to the technical field of
new energy planning. The method comprises the following steps: obtaining equipment parameters and cost parameters of wind farm unit reconstruction and
energy storage configuration, and respectively constructing a technical model and a cost model of the unit reconstruction and the
energy storage configuration based on an operation performance optimization target; a wind farm
grid connection examination and auxiliary service income calculation model embedded with
time sequence operation
simulation is constructed, and a quantitative mapping of technical features to income of the wind farm
grid connection examination and auxiliary service income calculation model is utilized; based on the quantitative mapping relationship of the technical features to the income, a double-layer optimization framework of flexibility improvement considering
investment cost and income is constructed according to the technical model and the cost model of the unit reconstruction and the energy storage configuration. The application can systematically improve the flexibility level and market competitiveness of the wind farm while ensuring safe and stable operation of the wind farm.
