Pricing of Short Circuit Current in High IBR-Penetrated System
With the growing penetration of Inverter-Based Resources (IBRs) in power systems, stability service markets have emerged to incentivize technologies that ensure power system stability and reliability.
Managing the Uncertainty in System Dynamics Through Distributionally Robust Stability-Constrained Optimization
To address this issue, a propagation mechanism from the uncertainty of the system dynamic parameters to the stability constraint coefficients is established.
Cyber Recovery from Dynamic Load Altering Attacks: Linking Electricity, Transportation, and Cyber Networks
To address the increasing vulnerability of power grids, significant attention has been focused on the attack detection and impact mitigation.
Control-mode as a Grid Service in Software-defined Power Grids: GFL vs GFM
In power systems with high penetration of power electronics, grid-forming control is proposed to replace traditional Grid-Following Converter (GFL) in order to improve the overall system strength and resist small-signal instability in weak grids by directly forming the terminal voltage.
Stability Constrained Optimization in High IBR-Penetrated Power Systems-Part II: Constraint Validation and Applications
Multiple operational constraints of power system stability are derived analytically and reformulated into Second-Order Cone (SOC) form through a unification method in Part I of this paper.
Stability Constrained Optimization in High IBR-Penetrated Power Systems-Part I: Constraint Development and Unification
To ensure system stability during system operation and to provide appropriate incentives in the future market-based stability maintenance framework, it is essential to develop a comprehensive set of power system stability constraints which can be incorporated into system operation, market design and planning problems.
Optimal Design of Neural Network Structure for Power System Frequency Security Constraints
Recently, frequency security is challenged by high uncertainty and low inertia in power system with high penetration of Renewable Energy Sources (RES).
Risk-Aware Objective-Based Forecasting in Inertia Management
The objective-based forecasting considers the asymmetric and non-linear impacts of forecasting errors on decision objectives, thus improving the effectiveness of its downstream decision-making process.
Scheduling of Software-Defined Microgrids for Optimal Frequency Regulation
Integrated with a high share of Inverter-Based Resources (IBRs), microgrids face increasing complexity of frequency dynamics, especially after unintentional islanding from the maingrid.
Voltage Stability Constrained Unit Commitment in High IBG-Penetrated Power Systems
Based on this, an optimal system scheduling model is proposed to minimize the overall system operation cost while maintaining the voltage stability during normal operation through dynamically optimizing the active and reactive power output from IBGs.
Frequency-Constrained Resilient Scheduling of Microgrid: A Distributionally Robust Approach
In order to prevent the potential frequency instability due to the high Power Electronics (PE) penetration under an unintentional islanding event, this paper presents a novel microgrid scheduling model which explicitly models the system frequency dynamics as well as the long/short term uncertainty associated with renewable energy resources and load.
