Due to the rapid increase of energy demand and environmental pollution caused by traditional fossil energy

a large number of low-cost

clean and environment-friendly distributed energy are connected to the power grid.Its volatility

randomness

intermittence and other characteristics also bring great challenges to the power system.This paper proposes a multi scenario decentralized coordination method for multi-area interconnected power system with wind power

which can effectively deal with the uncertainty of wind power and realize multi area coordinated consumption of wind power in interconnected power grid.Firstly

the economic dispatch model of wind power forecasting scenario is established

and the target cascade analysis method is used for decentralized coordination optimization; Secondly

the uncertain scenarios of wind power are generated by multi scenario sampling method

and the error correction and optimization of the economic dispatch model of the determined scenarios are carried out; Finally

the optimal generation scheduling scheme of the whole network is calculated by the iteration of decentralized coordination optimization and error correction optimization.The results of example analysis show that the proposed method can effectively deal with the uncertainty of wind power and achieve the purpose of cross regional consumption of large-scale wind power in energy Internet.
