计及动态安全的源网荷储三阶段协同调度方法
Three-Stage Dynamic Security-Constrained Coordinated Scheduling of Power Systems
【目的】随着电力系统中高比例分布式光伏、风电的接入，系统的安全稳定运行面临挑战。传统的优化调度方案在满足小时级功率平衡的基础上追求经济最优，忽略了动态频率与短路电流安全。为弥补这一空白，本文提出一种内嵌动态安全约束的源网荷储协同调度方法以保障电力系统的动态安全。【方法】提出一种基于再调度方法的三阶段迭代求解方法，首先求解传统的源网荷储协同优化模型，随后基于实时仿真对调度方案进行动态安全校验，包括频率安全校验和短路电流安全校验。若不满足动态安全约束，将基于灵敏度分析获取提升动态安全的增补约束并将其添加到调度模型中重新求解，该过程迭代至所有动态安全约束均得到满足。【结果】在HRP-38测试系统上进行算例分析，结果表明所提方法能够高效收敛于满足动态安全约束的调度方案。【结论】所提基于再调度的源网荷储协同调度方法为高可再生能源渗透的电力系统安全稳定运行提供了可行的解决方案。
[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.

Carbon dioxide removal technologies, such as bioenergy with carbon capture and direct air capture, are valuable for stringent climate targets. Previous work has examined implications of carbon removal, primarily bioenergy-based technologies using integrated assessment models, but not investigated the effects of a portfolio of removal options on power systems in detail. Here, we explore impacts of carbon removal technologies on electric sector investments, costs, and emissions using a detailed capacity planning and dispatch model with hourly resolution. We show that adding carbon removal to a mix of low-carbon generation technologies lowers the costs of deep decarbonization. Changes to system costs and investments from including carbon removal are larger as policy ambition increases, reducing the dependence on technologies like advanced nuclear and long-duration storage. Bioenergy with carbon capture is selected for net-zero electric sector emissions targets, but direct air capture deployment increases as biomass supply costs rise.

Frequency security is an essential issue in power system operation and planning, especially with the increasing penetration level of intermittent and non-synchronous energy sources, which causes insufficiency of inertial and primary frequency responses. Therefore, various studies must observe the frequency security in the problem formulation as objective function and/or constraints. This letter proposes a Frequency Security Index (FSI), which determines the frequency security based on all aspects of the frequency profile. This index presents a quantitative percentage for the frequency security in order to specify the relative distance from the insecure (0%), secure (100%), and absolute secure (200%) conditions. The FSI considers transient and steady-state aspects of frequency security based on the boundaries related to each power system requirements and standards. The applicability, correctness, and sufficiency of the proposed index are demonstrated based on the numerical results of a real large-scale power system.
