Decentralized Frequency-Domain Conditions for D-Stability with Application to DC Microgrids
Zelin Sun, Shanshan Jiang, Xiaoyu Peng +3
This paper proposes a decentralized method for regional pole placement, or -stability, in linearized networked systems. Existing LMI-based methods are hindered by conf…
Decentralized Analysis Approach for Oscillation Damping in Grid-Forming and Grid-Following Heterogeneous Power Systems
Xiang Zhu, Xiuqiang He, Hongyang Qing +1
This letter proposes a decentralized local gain condition (LGC) to guarantee oscillation damping in inverter-based resource (IBR)-dominated power systems. The LGC constrains the dy…
Aggregating Inverter-Based Resources for Fast Frequency Response: A Nash Bargaining Game-Based Approach
Xiang Zhu, Hua Geng, Hongyang Qing +1
This paper proposes a multi-objective optimization (MOO) approach for grid-level frequency regulation by aggregating inverter-based resources (IBRs). Virtual power plants (VPPs), a…
Dynamic Virtual Power Plants with Robust Frequency Regulation Capability
Xiang Zhu, Hua Geng, Hongyang Qing +3
The rapid integration of inverter-based resources (IBRs) into power systems has identified frequency security challenges due to reduced inertia and increased load volatility. This…
Optimal Frequency Support from Virtual Power Plants: Minimal Reserve and Allocation
Xiang Zhu, Guangchun Ruan, Hua Geng
This paper proposes a novel reserve-minimizing and allocation strategy for virtual power plants (VPPs) to deliver optimal frequency support. The proposed strategy enables VPPs, act…
Multi-Objective Sizing Optimization Method of Microgrid Considering Cost and Carbon Emissions
Xiang Zhu, Guangchun Ruan, Hua Geng +3
Microgrid serves as a promising solution to integrate and manage distributed renewable energy resources. In this paper, we establish a stochastic multi-objective sizing optimizatio…
