A New Fractional-Order Virtual Inertia Support Based on Battery Energy Storage for Enhancing Microgrid Frequency Stability

open access: yesFractal and Fractional, 2023
Microgrids have a low inertia constant due to the high penetration of renewable energy sources and the limited penetration of conventional generation with rotating mass. This makes microgrids more susceptible to frequency stability challenges.

Simulation Analysis of Frequency Regulation

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Frequency is one of the most important parameters reflecting the operation quality of the system. When the system is in steady-state operation, the frequency of the generator in the system is equal under steady-state operation. Because the load is changing at any time, this kind of balance is dynamic.

Real-time vehicle-to-grid control for frequency regulation with high frequency regulating signal [PDF]

open access: yesProtection and Control of Modern Power Systems, 2018
The large-scale popularization of electric vehicles (EVs) brings the potential for grid frequency regulation. Considering the characteristics of fast response and adjustment of EVs, two control strategies of automatic generation control (AGC) with EVs are proposed responding to two high frequency regulating signals extracted from area control error ...
