Wind-light-water coordinated power transmission and distribution system distributed optimization method

The invention discloses a wind-light-water coordinated power transmission and distribution system distributed optimization method. The method is characterized in that: complementation and difference of renewable energy water, wind, and light power generation characteristics are used to perform wind-light-water coordinated optimization, coordination between a power transmission network and a power distribution network are considered while the water, wind, and light are optimized coordinately, the transmission capacity of the power transmission network and renewable energy output in the power distribution network are coordinated, and the consumption of renewable energy sources is promoted; power distribution network line capacity limitation node voltage limitation, and power transmission network line capacity limitation and outgoing power limitation are considered at the same time in wind-light-water coordinated dispatching under transmission and distribution cooperation, renewable energy output in a power tran
