Delay-Dependent Stability Analysis of Modern Shipboard Microgrids

Burak Yildirim et al.

Summary: This study suggests a new application for delay-dependent stability analysis in a shipboard microgrid system, incorporating a virtual gain and phase margin tester to achieve desired stabilization. Time delay margin values are obtained and their accuracy in terms of gain and phase margin values is investigated, showing the accuracy in using real data of renewable energy sources and loads. A real-time hardware-in-the-loop simulation is used to confirm the applicability of the method for load frequency control in the shipboard microgrid.

Impact of electric vehicles aggregators with communication delays on stability delay margins of two-area load frequency control system

Ausnain Naveed et al.

Summary: This paper investigates the impact of electric vehicles (EVs) aggregator with communication time delay on the stability delay margin of a two-area load frequency control (LFC) system. The study proposes a new method to accurately determine system stability and root tendency with respect to time delay, and develops an analytical formula to compute delay margins. The results are verified by time domain simulations and a quasi-polynomial mapping-based root finder algorithm.

Impact of Electric Vehicle Aggregator with Communication Time Delay on Stability Regions and Stability Delay Margins in Load Frequency Control System

Ausnain Naveed et al.

Summary: This study investigates the impact of an electric vehicle (EV) aggregator with communication time delay on stability regions and stability delay margins of a single-area load frequency control (LFC) system. A graphical method and frequency-domain exact method are utilized to analyze the qualitative impact of the EV aggregator, with results validated through time-domain simulations and the QPmR algorithm.
