Given large-scale modern power systems with power electronic converters, the numerical simulation with subsynchronous oscillation (SSO) faces great challenges in engineering practice due to sharply enlarged modeling scale and high computational burden. To reduce the modeling scale, network partition and equivalent becomes a vital technique in numerical simulations. Although several methods have been

Linear Active Disturbance Rejection Control and Stability Analysis for Modular Multilevel Converters Under Weak Grid Journal of Modern Power Systems and Clean Energy (IF 6.3) Pub Date : 2023-06-01 Hailiang Xu, Mingkun Gao, Pingjuan Ge, Jiabing Hu
The modular multilevel converters (MMCs) are popularly used in high-voltage direct current (HVDC) transmission systems. However, for the direct modulation based MMC, its complex internal dynamics and the interaction with the grid impedance would induce the frequency coupling effect, which may lead to instability issues, especially in the case of weak grid. To effectively suppress the sub- and super-synchronous

Game-theoretical Model for Dynamic Defense Resource Allocation in Cyber-physical Power Systems Under Distributed Denial of Service Attacks Journal of Modern Power Systems and Clean Energy (IF 6.3) Pub Date : 2023-05-25 Bingjing Yan, Pengchao Yao, Tao Yang, Boyang Zhou, Qiang Yang
Electric power grids are evolving into complex cyber-physical power systems (CPPSs) that integrate advanced information and communication technologies (ICTs) but face increasing cyberspace threats and attacks. This study considers CPPS cyberspace security under distributed denial of service (DDoS) attacks and proposes a nonzero-sum game-theoretical model with incomplete information for appropriate

Integrated Frequency-constrained Scheduling Considering Coordination of Frequency Regulation Capabilities from Multi-source Converters Journal of Modern Power Systems and Clean Energy (IF 6.3) Pub Date : 2023-05-25 Jiaming Li, Ying Qiao, Zongxiang Lu, Wei Ma, Xin Cao, Rongfu Sun
As the proportion of renewable energy (RE) increases, the inertia and the primary frequency regulation (FR) capability of the power system decrease. Thus, ensuring frequency security in the scheduling model has become a new technical requirement in power systems with a high share of RE. Due to a shortage of conventional synchronous generators, the frequency support of multi-source converters has become

Scalable Distributed Optimization Combining Conic Projection and Linear Programming for Energy Community Scheduling Journal of Modern Power Systems and Clean Energy (IF 6.3) Pub Date : 2023-05-25 Mohammad Dolatabadi, Alberto Borghetti, Pierluigi Siano
In this paper, a new method to address the scheduling problem of a renewable energy community while considering network constraints and users' privacy preservation is proposed. The method decouples the optimization solution into two interacting procedures: conic projection (CP) and linear programming (LP) optimization. A new optimal CP method is proposed based on local computations and on the calculation

FPGA-Based Digital Implementation of Flexible Power Control for Three-Phase to Single-Phase MMC-Based Advanced Co-Phase Traction Power Supply System Journal of Modern Power Systems and Clean Energy (IF 6.3) Pub Date : 2023-05-25 Jiangpeng Yang, Hongjian Lin, Haotian Zhu, Zeliang Shu, Lan Ma, Changsong Cai, Pengcheng Zhang, Li He, Ruoyu Li, Shasha Song, Josep M. Guerrero
A three-phase to single-phase modular multilevel converter based advanced co-phase traction power supply (MMC-ACTPS) system is an effective structure to address the concerns of phase splitting and poor power quality of the conventional electrified railway. Due to the large number of MMCACTPS system modules, I/O resources and computing speed have high requirements on processors. Moreover, the module
