Controlling Grid-Connected Inverters under Time-Varying Voltage Constraints

no code implementations20 Nov 2023 Zixiao Ma, Baosen Zhang

A particular challenge in the operation of grid connected IBRs is the variations in the grid side voltage.

Optimal Power Flow for Integrated Primary-Secondary Distribution Networks with Center-Tapped Service Transformers

no code implementations23 Jun 2023 Rui Cheng, Naihao Shi, Zhaoyu Wang, Zixiao Ma

This proposed SDNet OPF model can be easily embedded into existing primary distribution network (PDNet) OPF models, resulting in a holistic power system decision-making solution for integrated primary-secondary distribution networks.

A Two-Level Simulation-Assisted Sequential Distribution System Restoration Model With Frequency Dynamics Constraints

no code implementations16 Jan 2021 Qianzhi Zhang, Zixiao Ma, Yongli Zhu, Zhaoyu Wang

This paper proposes a service restoration model for unbalanced distribution systems and inverter-dominated microgrids (MGs), in which frequency dynamics constraints are developed to optimize the amount of load restoration and guarantee the dynamic performance of system frequency response during the restoration process.

Singular Perturbation-based Large-Signal Order Reduction of Microgrids for Stability and Accuracy Synthesis with Control

no code implementations8 Oct 2019 Zixiao Ma, Zhaoyu Wang, Yuxuan Yuan, Tianqi Hong

Higher-level controller design and stability analysis of such high-order systems are usually intractable and computation-costly.
