Voltage Unbalance Compensation in Distribution Feeders Using Soft Open Points

Journal of Modern Power Systems and Clean Energy, 2022
Soft open points (SOPs) are power electronic devices that may replace conventional normally-open points in distribution networks. They can be used for active power flow control, reactive power compensation, fault isolation, and service restoration ...

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.

Coordinated control strategies for unbalanced voltage suppression and optimization of SOC of battery in a bipolar DC microgrid with voltage balancer

Energy Reports, 2022
The unbalanced loads and distributed generations (DGs) will lead to an unbalanced current in the neutral line and further result in a voltage imbalance which will increase circuit power consumption and affect the stable operation of the bipolar DC ...

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Improvements in Bidirectional Power-Flow Balancing and Electric Power Quality of a Microgrid with Unbalanced Distributed Generators and Loads by Using Shunt Compensators

Energies, 2018
Improper connections of unbalanced distributed generators (DGs) and loads in a three-phase microgrid cause unbalanced and bidirectional power flow problems. The unbalanced DGs and loads may also aggravate the electric power quality (EPQ), such as voltage

Unbalanced Funds Analysis under the Background of Coexistence of Planning and Market

Zhongguo dianli, 2020
In the process of electric power system reform in China, the coexistence of planning and market may not change in the short term. With electricity market expanding, the decoupling operation mode of planning and market is unsustainable. While the issue of
