SSSC optimization configuration-based power transmission capacity improvement method containing access of multiple wind power plants

The invention discloses a power transmission capacity improving method containing access of multiple wind power plants based on SSSC optimal configuration, and belongs to the technical field of electrical engineering. The method specifically comprises the steps of determining a probability model of wind speed and fan output; generating an initial scene, performing scene reduction, and extracting a representative typical operation scene; establishing an SSSC node power injection model and a power flow transfer entropy index, and performing site selection on the SSSC by taking the model and the index as an indirect optimization target; determining a ground state power flow based on an economic dispatching model, defining power flow transfer entropy index representation ATC, establishing a multi-objective optimization model, adopting a non-dominated sorting genetic algorithm retaining an elite strategy to solve, and sorting a Pareto solution set to determine an optimal configuration line of the SSSC; and an SSSC
