Probability Assessment on Voltage Stability of Power Grid Containing Wind Farms and Its Application in Reactive Power Optimization
摘要
Abstract
To analyze the influences of intermittence and randomness of wind driven generators on power grid, the stochastic response surface method (SRSM) was led in to build a probability assessment model for static state voltage stability of power grid, and the built model was led into the solution of multi-objective reactive power optimization. The SRSM can express the relation between the probability parameters of active power output of wind driven generators and the load margin of the response in polynomial form, and the statistical information of the response could be assessed by faster simulation process. Simulation results of IEEE 14-bus system connected with wind farm showed that higher efficiency and accuracy could be achieved by the proposed probability model, thus the adaptability of reactive power optimization scheme to wind speed was improved, and the influences of stochastic power output of wind driven generators on power grid operation could be overall considered to find out more reasonable reactive power scheduling scheme.关键词
