Three-Stage Dynamic Security-Constrained Coordinated Scheduling of Power Systems
摘要
Abstract
[Objective]High renewable energy penetration exacerbates power-system stability challenges,particularly concerning frequency security and short-circuit current adequacy.Conventional cost-driven scheduling methods may violate these dynamic security limits.However,directly embedding detailed nonlinear security models into scheduling model is computationally prohibitive.This study addresses this gap by proposing a practical and tractable solution framework to ensure the dynamic security of power systems with high renewable energy penetration.[Methods]A rescheduling-based iterative framework is proposed that enforces dynamic security through simulation-guided constraint generation.This method first solves a conventional scheduling model.Subsequently,high-fidelity dynamic security assessments—including frequency-response analysis and short-circuit analysis—are performed on the resulting schedule.Upon detection of security violations,sensitivity-based linear security constraints are generated and incorporated into the scheduling optimization formulation.This process iterates until all dynamic security criteria are satisfied.[Results]Simulations on the HRP-38 test system demonstrate that the proposed approach converges efficiently to schedules that are both secure and economically competitive.It effectively eliminates dynamic security violations while incurring only a modest increase in operational cost,thereby validating its capability to maintain system security while preserving economic efficiency.[Conclusions]The framework presented in this study offers a practical and tractable pathway to reliability-aware scheduling in systems with high renewable penetration.关键词
