A review on the suitability of virtual inertia strategies for the next generation of low-inertia power systems

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Modern power grids are increasingly challenged by the lack of inertia caused by the high penetration of renewable energy sources (RES). This low inertia leads to reduced frequency stability and greater vulnerability to disturbances. To address this issue,

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Transient Voltage Support Strategy of Grid-Forming Medium Voltage Photovoltaic Converter in the LCC-HVDC System

CSEE Journal of Power and Energy Systems
The participation of photovoltaic (PV) plants in supporting the transient voltage caused by commutation failure in the line-commutated-converter-based high voltage direct current (LCC-HVDC) system is of great significance, as it can enhance the DC ...

Smooth switching control method for grid-following and grid-forming converters

Journal of Physics: Conference Series
Abstract In the end grid with high penetration of new energy, a single control mode of grid-following or grid-forming makes it difficult to balance stability, economy, and grid-supporting capabilities. To solve the above problems, starting from the topological structures and mathematical models of grid-following and grid-forming ...

Unleashing the Power of Machine Learning in Nanomedicine Formulation Development

Advanced Functional Materials, EarlyView.
A random forest machine learning model is able to make predictions on nanoparticle attributes of different nanomedicines (i.e. lipid nanoparticles, liposomes, or PLGA nanoparticles) based on microfluidic formulation parameters. Machine learning models are based on a database of nanoparticle formulations, and models are able to generate unique solutions

Coordinated Control of Energy Storage in Networked Microgrids under Unpredicted Load Demands

, 2018
In this paper a nonlinear control design for power balancing in networked microgrids using energy storage devices is presented. Each microgrid is considered to be interfaced to the distribution feeder though a solid-state transformer (SST).
