Optimizing Electric Vehicle Charging Scheduling With Deep Q Networks and Long Short‐Term Memory‐Based Electricity and Battery State of Charge Prediction

Energy Science &Engineering, EarlyView.
Schematic diagram showing the proposed approach for EV charging/discharging. ABSTRACT The number of electric vehicles (EVs) on the road is rising as a result of recent advancements in EV technology, and EVs are important to the smart grid economy. Demand response schemes involving electric vehicles have the potential to dramatically reduce the cost of ...

Reliability model and algorithm research on HVDC system and flexible HVDC system

The Journal of Engineering, 2019
The main difference between flexible high-voltage direct current (HVDC) system and the traditional HVDC system is that there are two control degrees of freedom in the flexible HVDC system that is the amplitude and phase angle of the output voltage. While,

Monitoring animal movement diversity as a component of biodiversity

Frontiers in Ecology and the Environment, EarlyView.
Animal movement is increasingly being quantified in novel ways, with high potential for integration into broad‐scale efforts to monitor biological diversity. Here, we define movement diversity as a form of biodiversity, measuring variation in animal movement from the level of individual animals to communities. We present a framework to develop a common

Land Use Policy and Racial Segregation

International Studies of Economics, EarlyView.
ABSTRACT Land use policies, though seemingly race‐neutral, can inadvertently contribute to racial segregation. Our study focuses on examining the impact of minimum lot size regulations on the likelihood of ethnic minorities integrating into a community, which reveals compelling evidence suggesting that black households exhibit a preference for smaller ...
