Published: March 23, 2023

Ghana's electricity generation mix does not include utility-scale wind power plants to contribute its supply. Thus, the country is yet harness potential benefits that energy could offer, such as diversification of mix, promoting a low-carbon economy, and increasing capacity. This study evaluated turbines suitable for developing in Adafoah using multicriteria decision-making methods. After that, RETScreen software was employed perform evaluate techno-economic viability deploying 10 MW plant generation. The results showed ranging from 1 1.5 are site. Also, would generate about 93 GWh annually with capacity factor 22%. findings also reveal feed-in tariff (FiT) lower than US$0.15/kWh lucrative development Adafoah. Furthermore, without financial incentives, levelized cost (LCOE) US$0.143/kWh. In addition, saves 33% carbon dioxide (CO2) emissions compared utility grid. sensitivity analysis demonstrates project's indicators resilient capital subsidies, inflation, discount rate, FiT, speed variations. study's suggest similar locations can improve access, reduce greenhouse gas emissions, promote sustainable development. useful decision-makers, stakeholders, investors sector Ghana.

Advancing individual decision-making: An extension of the characteristic objects method using expected solution point

Information Sciences, Journal Year: 2023, Volume and Issue: 647, P. 119456 - 119456

Published: Aug. 11, 2023

This study introduces an extension of the Characteristic Objects Method (COMET) by incorporating Expected Solution Point (ESP) approach to enhance individual decision-making. By integrating ESP methodology, we aim simplify decision-making, particularly when facing a vast decision matrix concerning multiple criteria. We demonstrate efficacy proposed ESP-COMET method applying it with one or two ESPs, thereby examining its impact on ranking alternatives according personal customer preferences. In order provide practical example, use dataset used cars show how facilitates selection most suitable vehicle based needs. The main goal this paper is can help adapt decisions needs and expectations. also introduce novel efficient for determining characteristic values in personalized which plays crucial role ensuring higher accuracy method. Additionally, compare such methods as Stable Preference Ordering Toward Ideal (SPOTIS) Reference (RIM). addresses research gap introducing easy way define preferences within COMET, enabling responsible

A multi-dimensional sensitivity analysis approach for evaluating the robustness of renewable energy sources in European countries

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 469, P. 143225 - 143225

Published: July 24, 2024

The necessity of making reliable decisions is exceptionally important in the field sustainable development, particularly when evaluating management renewable energy sources. A thorough analysis becomes imperative complex decision problems where various factors influence outcomes. Multi-Criteria Decision Analysis (MCDA) methods have emerged as valuable tools for addressing such challenges, enabling decision-makers to navigate through conflicting criteria and make informed choices. Combined with sensitivity approaches, comprehensive assessments can be achieved, ensuring robustness decision-making processes. To increase reliability results, different aspects input data fluctuations should examined provide a broader view stability results. This paper proposes multi-dimensional approach assess source (RES) development selected European countries. By RES terms electricity consumption generation, study addresses key components development. It offers holistic perspective on result by analyzing five dimensions: comparative four MCDA methods, varying weights scenarios, probabilistic modifications, relevance identification, ranking stability. enhances providing insights policymakers prioritizing technologies. provided open-source implementation promotes transparency accessibility support systems.

Superheat Degree Recognition of Aluminum Electrolysis Cell Using Unbalance Double Hierarchy Hesitant Linguistic Petri Nets

IEEE Transactions on Instrumentation and Measurement, Journal Year: 2023, Volume and Issue: 72, P. 1 - 15

Published: Jan. 1, 2023

Superheat degree is a core technical parameter and management index of aluminum electrolysis cell. However, the exiting methods have limited abilities when applied to superheat recognition cell (SDRAEC). In addition, important hesitant ignored in unbalance double hierarchy linguistic term set. To address these issues, an Petri net model extended TOPSIS proposed for SDRAEC. this model, coupling relationships among variables made be explicit knowledge, set represent value knowledge parameter. The relative entropy introduced enhance performance TOPSIS. Moreover, hybrid averaging concurrent reasoning algorithm improve efficiency. Finally, thermal analysis experiments conducted real-world plant are used demonstrate effectiveness method. Compared with other methods, accuracy SDRAEC has been increased 89.00%.
