At present

it is urgently needed to study the wind power grid-connected analysis method to realize the unified development of wind power and power grid so to provide technical support for wind power and grid operation and planning. In this paper

the production simulation method based on different time scales improvement is proposed to analyze the operation situation of each chain from power generation

transmission and operation after large scale grid connection of wind power

the correlation between regional wind power output and load and the peaking ability of regional conventional power supply in different seasons are analyzed. The conventional power supply combination with safety constraints is optimized and considered. The wind power consumption in continuous and operation situation of common power supply are analyzed based on the continuous time sequence

which provides technical data support for network planning of regional power grid.
