However, the performance of the conventional dissipating energy flow (DEF) is significantly affected by measurement noise and other irrelevant modal components. To address this challenge, an optimal subspace-enhanced (Os-enhanced) dynamic mode decomposition (DMD)-assisted DEF-based FOSL is proposed in this paper using synchrophasor measurement. First, Os-enhanced DMD is employed to decompose multi-channel measurements into time-domain responses of individual modes. Then, the time-domain components associated with FO are distinguished from the decomposed modes based on the rate of change of modal energy, and are subsequently used to calculate the DEF at all generator buses. Furthermore, the rate of forced energy is introduced as an indicator of energy flow direction to localize the FO source. The performance of the Os-enhanced DMD-assisted DEF is evaluated by the simulated data from IEEE 16-machine 5-area system and field phasor measurement unit (PMU) measurement data from Independent System Operator New England (ISO-NE). Comparative results demonstrate that the Os-enhanced DMD-assisted DEF achieves improved accuracy and robustness for localizing FO sources under noisy conditions.","PeriodicalId":51326,"journal":{"name":"Journal of Modern Power Systems and Clean Energy","volume":"14 5","pages":"1622-1633"},"PeriodicalIF":6.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11458068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149033998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high dimensionality and strong nonlinearity of this model, due to the aggregated distributed energy resource (DER_A) component, greatly complicate the reliable parameter estimation. We put forth a parameter interdependency analysis to partition the entire parameter space into smaller subsets, thereby decomposing the original high-dimensional estimation problem into multiple tractable subproblems. After applying the interdependency-based parameter grouping, the estimation for each subset is performed using both the Levenberg-Marquardt (LM) algorithm and the enhanced snake optimizer (ESO), demonstrating the solver-agnostic improvements in the convergence stability and estimation accuracy. An initialization strategy is developed to improve the robustness of subsequent optimization. Case studies in the New England 68-bus system confirm that the interdependency-based parameter grouping significantly improves the convergence speed, numerical stability, and estimation accuracy across different disturbance scenarios. The ability of the proposed estimation method is further validated through real-world measurements, and it can be broadly applicable to other modeling problems.","PeriodicalId":51326,"journal":{"name":"Journal of Modern Power Systems and Clean Energy","volume":"14 5","pages":"1820-1832"},"PeriodicalIF":6.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11495403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149034215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the available adjustment capacity is limited and short-lasting, requiring reserve power for more capacity. For wind farms (WFs), reserve power dispatching is important both at steady state and during dynamic grid frequency support process, as it influences the lifespan and cost of WFs. Moreover, power dispatching at steady state and during dynamic grid frequency support process may have a mutual impact on their performance. For this regard, this paper proposes a hierarchical reserve power dispatching (HRPD) strategy of WFs for grid frequency support. The hierarchical concept is reflected on the WF and the WT control layers spatially, as well as on the steady-state layer and the dynamic grid frequency support layer temporally. First, the central controller of WF determines the reserve power command of each WT at the steady-state layer according to the total reserve power requirement, where the total fatigue of WFs and the fatigue distribution among WTs are considered to reduce the operating fatigue of the WF and maintain the consistency of WTs. Meanwhile, the WT controller assesses the real-time grid frequency support capability of each WT at the dynamic grid frequency support layer, according to the available kinetic energy of rotor and the real-time pitch angle to optimize the utilization of regulation capacity while maintaining the performance of grid frequency support. Based on this, the central controller adjusts and assigns a dynamic frequency droop coefficient to each WT. Case studies validate the performance of the proposed HRPD strategy in total fatigue reduction, fatigue distribution restriction, and grid frequency support.","PeriodicalId":51326,"journal":{"name":"Journal of Modern Power Systems and Clean Energy","volume":"14 5","pages":"1609-1621"},"PeriodicalIF":6.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11484048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149033445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods typically aggregate the contributions of all generation units or rely on system identification during disturbances. However, these methods may yield inaccurate or incomplete results in systems with a high penetration of inverter-based resources (IBRs), as IBRs may reach their power reserve limits (PRLs) and fail to provide the expected frequency support. To overcome this limitation, this paper proposes an assessment method of equivalent inertia and PFR of power systems considering PRLs of IBRs. In addition, dead zones and control delays are incorporated to further enhance the accuracy of the assessment. Based on the assessment results, an optimal parameter-setting approach for equivalent inertia and PFR is then developed. Notably, the theoretical optimal settings are generally difficult to achieve in practice, implying that conventional parameter settings may lead to significantly lower equivalent inertia than expected.

However, when applied to complex large-scale power systems, two prominent challenges emerge: ① high-dimensional discrete-continuous hybrid action space poses great adaptation difficulty for regular DRL methods, as they are designed primarily for purely discrete or continuous action spaces; and ② unguided exploration within vast action spaces leads to inefficient convergence performance. To mitigate these limitations, this paper develops a knowledge-guided hybrid DRL-based method for transient stability emergency control. The proposed method adopts a novel hybrid policy to represent the hybrid action domain, and employs a novel derivative-free DRL for optimization, which eliminates the training instability issues associated with jointly optimizing gradients for different action types. Then, the prior domain knowledge is utilized to formulate mask rules and incorporate them into DRL training through trainable action mask (TAM) technique to guide exploration. Moreover, the proposed method is further integrated into a hierarchical DRL framework to alleviate computational complexity and enhance scalability. Case studies on the IEEE 300-bus system show that the proposed method improves solution quality by 52.9% and 42.8% compared with purely discrete and conventional hybrid action DRL methods, and achieves an 80.0% improvement in convergence efficiency compared with the method without knowledge guidance.","PeriodicalId":51326,"journal":{"name":"Journal of Modern Power Systems and Clean Energy","volume":"14 5","pages":"1634-1646"},"PeriodicalIF":6.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11458072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149033816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
