Negative Imaginary and Passivity Properties of Synchronous Machine Systems
Maryam Khodabakhshloo, Elizabeth L. Ratnam, Ian R. Petersen
The recent rapid proliferation of renewable energy is fundamentally changing the dynamic operations of power systems, necessitating new approaches to assess stability for these hig…
Equilibrium points and stability of synchronous machine systems
Maryam Khodabakhshloo, Elizabeth L. Ratnam, Ian R. Petersen
This paper investigates equilibrium points and stability in two synchronous machine configurations: (i) a single generator with an impedance load and (ii) two interconnected machin…
An Electricity Market with Reactive Power Trading: Incorporating Dynamic Operating Envelopes
Zeinab Salehi, Elizabeth L. Ratnam, Yijun Chen +3
Electricity market design that accounts for grid constraints such as voltage and thermal limits at the distribution level can increase opportunities for the grid integration of Dis…
Peer-to-Peer Energy Markets With Uniform Pricing: A Dynamic Operating Envelope Approach
Zeinab Salehi, Yijun Chen, Ian R. Petersen +3
The recent widespread adoption of rooftop solar backed by battery storage is enabling energy customers to both produce and consume electricity (i.e., prosumers of electricity). To…
Electric Grid Topology and Admittance Estimation: Quantifying Phasor-based Measurement Requirements
Norak Rin, Iman Shames, Ian R. Petersen +1
In this paper, we quantify voltage and current phasor-based measurement requirements for the unique estimation of the electric grid topology and admittance parameters. Our approach…
On the Stability of Networked Nonlinear Negative Imaginary Systems with Applications to Electrical Power Systems
Yijun Chen, Kanghong Shi, Ian R. Petersen +1
In the transition to achieving net zero emissions, it has been suggested that a substantial expansion of electric power grids will be necessary to support emerging renewable energy…
Discrete-time Integral Resonant Control of Negative Imaginary Systems: Application to a High-speed Nanopositioner
Kanghong Shi, Erfan Khodabakhshi, Prosanto Biswas +2
We propose a discrete-time integral resonant control (IRC) approach for negative imaginary (NI) systems, which overcomes several limitations of continuous-time IRC. We show that a…

Yijun Chen, Kanghong Shi, Ian R. Petersen +1
This paper proposes a unified methodology for voltage regulation, frequency synchronization, and rotor angle control in power transmission systems considering a one-axis generator…
Digital control of negative imaginary systems: a discrete-time hybrid integrator-gain system approach
Kanghong Shi, Ian R. Petersen
A hybrid integrator-gain system (HIGS) is a control element that switches between an integrator and a gain, which overcomes some inherent limitations of linear controllers. In this…
Hybrid integrator-gain system based integral resonant controllers for negative imaginary systems
Kanghong Shi, Ian R. Petersen
We introduce a hybrid control system called a hybrid integrator-gain system (HIGS) based integral resonant controller (IRC) to stabilize negative imaginary (NI) systems. A HIGS-bas…
Competitive Equilibrium in Microgrids With Dynamic Loads
Zeinab Salehi, Yijun Chen, Ian R. Petersen +2
In this paper, we consider microgrids that interconnect prosumers with distributed energy resources and dynamic loads. Prosumers are connected through the microgrid to trade energy…
