Optimal Dispatch Method for Distribution Network Considering Synergy Between Improved Convex Inner Approximation and Feasible Solution Recovery
摘要
Abstract
Under the strategy of carbon emission peak and carbon neutrality,the high penetration of renewable energy imposes higher requirements on the secure and stable operation of power systems.How to enhance economic performance under a secure operational framework has become a significant issue.To address this,this paper proposes an optimal dispatch method integrating improved convex inner approximation with feasible solution recovery.First,a dynamic boundary mechanism is proposed to refine the convex inner approximation method and construct an optimization model.This approach strictly ensures security while significantly expanding the feasible region,thereby establishing a safety foundation for better economic performance.Second,by incorporating a feasible solution recovery mechanism,the initial feasible solution undergoes gradient-guided,refined and coordinated adjustment of active and reactive power based on sensitivity information.After being fully validated by AC power flow analysis,a more secure and economically favorable dispatch plan is ultimately obtained.Finally,the simulation conducted on IEEE 33-bus,PG&E 69-bus,and IEEE 118-bus distribution systems using the YALMIP-CPLEX platform demonstrates that the proposed method achieves efficient dispatch while rigorously ensuring security.关键词
