A new energy power generation-containing cross-regional power grid unit combination decentralized coordination optimization strategy

The invention discloses a new energy power generation-containing cross-regional power grid unit combination decentralized coordination optimization strategy. The method comprises steps of based on thetarget cascade technology, taking a boundary node voltage phase angle value influencing the power of the interconnection line between the interconnected power grids as an inter-region coordination variable; the problem of circulation between regions is avoided; an upper layer coordinator is formed for coordinating and optimizing voltage phase angles of boundary nodes of all the areas, a lower layer is optimized for parallel solving of SCUC problems of all the areas, convergence is judged through alternate iteration solving of the upper layer coordinator optimization problem and the lower layer coordinator optimization problem, and if all the areas converge at any time, iteration is finished, and an optimal solution is obtained; In this way, coordinated optimization of the unit starting and stopping plan, the stan
