Complete Characterization Method of AC Feasible Loadability Region in Power Systems
摘要
Abstract
[Purposes]The steady-state security region represents the set of AC feasible power in-jections that satisfy operational constraints in the power system.To fully explore and characterize the flexibility of power system load demand,the steady-state security region is projected onto the load de-mand space and an AC feasible loadability region is defined.[Methods]First,a nonlinear AC power flow model was used to completely characterize the AC feasible loadability region of the system.At the same time,to explore the impact of load characteristics on AC feasible loadability region,a poly-nomial load model(ZIP load model)describing nonlinear load characteristics was introduced into the load domain model.Finally,the advantages of the proposed characterization method in fully and accu-rately characterizing the loadability region were verified through numerical calculations.[Results]By comparing the proposed method with existing methods on the IEEE 30-bus,IEEE 57-bus,and IEEE 118-bus systems,the results demonstrate that the characterization obtained in this paper is more precise,validating the accuracy and superiority of the proposed method.关键词
