Levelized Cost of Energy-Oriented Modular String Inverter Design Optimization for PV Generation System Using Geometric Programming

IEEE Access, 2022
Levelized cost of energy (LCOE) is a commonly used metric to assess the cost-to-benefit ratio over the lifetime of an energy resource, such as photovoltaics (PV); however, power electronics engineers tend to rely on metrics such as efficiency and power ...

Selecting Between Hydrogen and Methanol for Fuel Cell‐Organic Rankine Cycle Hybrid Power Systems: A Comparative 4E Analysis

Energy Science &Engineering, EarlyView.
A 4E comparison of PEMFC‐ORC and DMFC‐ORC systems shows that PEMFC‐ORC achieves 21% higher energy efficiency, while DMFC‐ORC obtains 31% higher exergy efficiency and 57% lower levelized cost of electricity. However, DMFC‐ORC emits nearly twice the annual carbon dioxide equivalent of PEMFC‐ORC.

A Case Study on Domestic and International Tidal Current Energy LCOE Analysis and a Review of Cost Reduction Pathway

, 2023
본 연구에서는 조류발전 균등화발전비용(Levelized Cost of Energy, LCOE) 분석 사례를 조사하여, 누적설비용량에 따른 LCOE 범위를 추정하고, LCOE의 주요 구성요소에 대한 민감도를 분석하였으며, 마지막으로 LCOE 저감방안에 대하여 고찰하였다. 조류발전 LCOE는 누적설비용량이 1MW에서 1GW까지 증가할 때 ￦520~800/kWh에서 ￦142~285/kWh으로 감소하는 것으로 추정되었으며, LCOE의 주요 구성요소에 대하여 ...

Renewable Resource Curse Hypothesis: Could Renewable Resources Foster Sustainable Development?

Sustainable Development, EarlyView.
ABSTRACT This study explores whether the resource curse hypothesis applies to renewable energy by introducing a novel metric of renewable resource rent. Using a panel dataset of 46 countries (2010–2022), we define renewable rent as the product of electricity generation and the gap between industrial electricity price and levelized cost (LCOE).

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 920-941, July 2026.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage ( voc) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets. Results across three PV installations
