However, the movement of traction trains causes real-time changes in the resistance of the traction network, leading to variations in power sharing at traction substations (TSSs) determined by droop control, thereby impacting the voltage operation quality of the DC traction power supply system (TPSS). In this paper, an adaptive power-voltage hierarchical control strategy considering rational traction power sharing and voltage compensation based on the consensus algorithm is proposed to mitigate the impact of train movement. Firstly, to enhance the convergence speed of inter-station communication algorithms in the system layer control, an improved consensus algorithm with a convergence factor is proposed to calculate the average values of TSS state variables needed for the local layer control. Secondly, in the local layer control, the per-unit average power of TSSs is introduced to compensate for the impact of train movement on the droop coefficient. Furthermore, to reduce power loss in the traction network, a base quantity for virtual power is proposed for further compensation of the droop coefficient. Through dynamic compensation of the droop coefficient, a rational sharing of traction power according to rated capacity and power supply distance at TSSs is achieved. Moreover, the voltage average is utilized for secondary compensation of voltage deviations at TSSs. Finally, simulations based on a four-terminal DC TPSS have been established to validate the effectiveness of the proposed method in terms of power sharing and voltage control.</div></div>","PeriodicalId":50547,"journal":{"name":"Electric Power Systems Research","volume":"245 ","pages":"Article 111642"},"PeriodicalIF":3.3,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance system resilience and enable rapid recovery after an attack, this paper proposes a novel two-stage recovery strategy specifically designed to address FDIAs. In the first stage, a detection method based on Normalized State Variable Residuals (NSVR) is introduced. By leveraging the distinct convergence behaviors of Weighted Least Squares (WLS) and the Extended Kalman Filter (EKF) under FDIAs, NSVR serves as an effective metric for detecting compromised measurements. The second stage employs a multi-step prediction compensation (MSPC) approach for attack correction. After identifying the attacked buses in the first stage, the prediction step of the EKF is utilized to compute the predicted values of the measurements. These predicted values are then selectively used to replace tampered measurements, reconstructing a set of corrected measurements for subsequent state estimation. Comprehensive simulation experiments were conducted on IEEE 14-bus and IEEE 30-bus test systems. The results confirm the efficacy of the proposed algorithm in accurately detecting FDIAs and achieving recovery of the power system.</div></div>","PeriodicalId":50547,"journal":{"name":"Electric Power Systems Research","volume":"245 ","pages":"Article 111632"},"PeriodicalIF":3.3,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143696624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a novel tri-level method for coordinated planning of flexible transmission grid and distribution grid (TSG-DSG) is proposed considering normal operational conditions and severe fault conditions; moreover, a novel network structure regulation as well as coal-fired power units and energy storage systems are employed as flexible tools for flexibility enhancement of transmission and distribution system under static security and transient stability framework.

By leveraging grid-forming converters and simulating the properties of rotating masses, this idea allows modern grids to move away from fossil fuels towards a more sustainable future without compromising sustainability. This study introduces the application of green inertia within four state-of-the-art grid-forming DC-DC converters designed for battery integration.

Leveraging the Virtual Compound DC Machine (VCDCM), this research introduces novel inertia emulation techniques, marking the first implementation of VCDCM in DAB, ThPh-DAB, and DAHB converters. Extensive simulations highlight the effectiveness of these converters in stabilizing DC microgrid performance while balancing technical efficiency and cost-effectiveness.

The decision-making paradigm integrates spatial considerations based on the population distribution of different regions, thus predicting their battery swapping demand. To accommodate this demand, MBSS are loaded with a determined number of batteries. As these batteries are depleted, MBSS return to the BSS to deposit empty units and procure fully-charged ones. The BSS, in its operational dynamics, holds these depleted batteries, strategically charging them based on dynamic energy prices to optimize grid sales and increase revenue. A mixed integer programming model has been formulated and developed to offer a systematic solution to this multifaceted problem. Results show that Case Study I prioritizes battery swap operations, while Case Study II allocates more capacity to energy sales. Ultimately, Case Study I achieves higher profitability than Case Study II, despite the latter’s increased energy sales revenue.
