Static Security Region Analysis of Power System With Large Scale New Energy Based on Heuristic Algorithm

Large-scale new energy grid integration increases the uncertainty of the power system, and traditional stability analysis methods have limitations. Therefore, the static stability analysis of the system is considered from the perspective of three-dimensional static security region (SSR). In view of the shortcomings of traditional algorithms such as long time and low accuracy, IPSO-RLS hybrid algorithm was proposed. The algorithm based on continuous power flow data, tracked system safety critical points of voltage active and reactive power, formed SSR critical surface. Used DIgSILENT /Power Factory software to simulate and analyse three wind farm regions of Hami Power Grid. Finally, sensitivity analysis method was used to verify the stability and feasibility of SSR surface. The results showed that the IPSO-RLS hybrid algorithm has good robustness and practicability in analyzing SSR of high proportion new energy power system.
