Techno-Economic Assessment of Floating Solar Photovoltaics on Inland Water Bodies: Comparative Insights with Land-Based PV Systems and Implications for Sri Lanka
Fast development of solar photovoltaic (PV) has also rendered an important part of the international shift to low-carbon power systems. Nonetheless, the traditional ground-mounted PV systems are currently experiencing more and more difficulties in the form of limited land, being rivaled by agricultural and urban land development, and high cost of land acquisition, especially in …
Reinforcement Learning Control Strategies for Virtual-Inertia Grid-Connected Inverters and Stability
As inverter based renewable energy increases, modern power systems are faced with reduced inertia which makes it a major source of concern in the frequency stability and the momentary performance. Inverters based on gridforming inverter configurations with virtual inertia control have become a valid solution, and reinforcement learning is an adaptive optimization of control parameters, …
Energy Harvesting-Enabled Self‑Powered Internet of Things Systems: A Comprehensive Review of Multi‑Source Architectures and Ultra‑Low‑Power Integration
The rapid expansion of the Internet of Things (IoT) has created a strong demand for sustainable, reliable, and maintenance-free power sources for distributed sensor nodes. Traditional battery-powered IoT systems suffer from limited lifetime, frequent replacement requirements, high maintenance costs, scalability limitations, and environmental concerns. Energy harvesting provides an attractive alternative by converting ambient sources such …
A Review of Usage, Challenges, and Sustainable Innovations of Plastic Packaging in Sri Lanka
This study evaluates the issues in plastic packaging in Sri Lanka through its usage and environmental and health challenges. The target of this paper is integrating the knowledge about single-use plastics, evaluating the current waste management practices, and finding sustainable packaging. This review proposes actionable strategies for transitioning towards a sustainable circular economy and packaging …
Material Selection Criteria for Lightweight Design in Commercial Aircraft
Reducing structural weight in commercial aircraft is critical because it improves fuel efficiency, payload capacity, environmental performance, operating load, and maintenance cost. This study examines material selection criteria for lightweight aircraft design using the Boeing 777 family as a case study. Material selection depends on factors such as strength-to-weight ratio, stiffness-to-weight ratio, fatigue resistance, impact …
