Bi-level Optimal Configuration of STATCOM in Wind Power Grid-connected System Considering Available Transfer Capacity

Targeting the problem of optimal location and capacity of static synchronous compensator （STATCOM）， the paper establishes a bi-level optimization configuration model of STATCOM in wind power integrated system considering the available transfer capacity， static voltage stability and investment cost. The scenario division of wind power output is done based on backward reduction method. The upper layer is a multi-objective optimal allocation layer， and the lower layer is a optimal power flow calculation layer. By adding the chaos initialization to the multi-objective gray wolf algorithm and introducing the speed calculation method of a particle swarm optimization algorithm， a multi-objective gray wolf particle swarm optimization algorithm based on the grid method is proposed to solve the multi-objective optimization problem. The feasibility of the model and the effectiveness of the algorithm improvement are verified by solving the model in an IEEE 30-node system.
