An analytical expression to determine the necessary battery voltage for synchronous rectification on the LMSWT Permanent Magnets Synchronous Generator (PMSG) was derived. It was found that the battery voltage for synchronous rectification should be two times higher than that of the passive strategy for an identical generator. The performance of the LMSWT under synchronous rectification with Field Oriented Control (FOC) and Optimal Torque (OT) Maximum Power Point Tracking (MPPT) was measured experimentally on a real scale wind turbine emulator under steady wind conditions. It was found that for the passive Diode Rectifier (DR) configuration, the Annual Energy Production (AEP) estimation was (16-38%) lower than for the synchronous rectification strategy.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116951762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variable nature of irradiation and temperature affects energy production especially when associated with unpredictable variations of the load. To compensate for these load and production fluctuations, a stand-by energy storage system is required. This work focuses on the modeling and performance analysis of a hybrid PV-battery system (lithium ion) connected to a direct current (DC) micro-grid. Maximum power point tracking (MPPT) and proportional integral (PI) controls are used to extract and stabilize the maximum power of the photovoltaic generator at any time. The study discusses the performance of each autonomous hybrid subsystem validated by simulations and performed under severe weather conditions and a variable DC load. The obtained results show the importance that can have a SS by ion-lithium battery in an autonomous micro-grid of solar energy production.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126940498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology is designed to provide a standardized approach for evaluating the energy performance of buildings and identifying areas for improvement. The methodology includes a set of performance indicators that are used to assess the energy efficiency of a building. These indicators are based on the building’s energy consumption, its physical characteristics, and its operational parameters. The methodology also includes a set of guidelines for the evaluation of the baseline level of the specific annual consumption of primary energy resources in building. The paper concludes that the proposed methodology can help to promote energy efficiency and reduce energy consumption in buildings in Azerbaijan, which could have significant environmental and economic benefits. The proposed certification methodology could be adapted and transposed to other countries in the region.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130483369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Public-private partnerships are one of the key financial mechanisms to realise the Sustainable Development Goal (SDG) 7 objective, enabling governments to overcome the barriers of drawing finance and know-how towards rural energy projects. The Bangladeshi Solar Home Systems (SHS) programme was successfully established through a public-private partnership (PPP) model, resulting in the programme becoming the most extensive off-grid solar programme globally. The PPP model succeeded in securing USD 696 million in financing, and at the height of success, more than 12.5 per cent of the people in Bangladesh enjoyed renewable energy access through the SHS programme. Establishing the PPP as a successful delivery mechanism to disseminate further energy access, but do these PPP agreements facilitate an enabling environment required to sustain long-term energy provision in rural communities? This paper discusses the SHS case and highlights some of the lessons learned for long-term energy provision to the rural areas of the Global South. The case of Bangladesh underpins the importance of including the socio-economic profiles of the stakeholders in the planning and implementation of energy projects to ensure the long-term provision of energy. Additionally, the government must hold a strong central position in the guiding long-term energy policy vision. Without the inclusion of such factors, the obtainment of sustainable energy can fall short.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129091048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a consequence of numerous obstacles, they are unable to transmit the energy they generate. This fact necessitates the incorporation of energy storage solutions to circumvent this substantial disadvantage. In the sphere of energy storage systems, the production of green hydrogen using various types of electrolyzers powered by excess energy derived from renewable sources has a promising future. Although renewable hydrogen appears to be a more attractive option for replacing obsolete storage systems, it presents significant storage difficulties. Matlab/Simulink is used in this study to demonstrate a comprehensive model of a hydrogen subsystem consisting of a proton exchange membrane electrolyzer and a storage vessel. The PEM model employs recently developed regression models to determine the hydrogen flowrate at varying electrolyzer current inputs. By applying a specific compression pressure, the established models demonstrate how hydrogen behaves dynamically in the storage state.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128867490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy routers (ERs), which control data and power flows, are used to transfer energy between parties. The power routing problem seeks to identify the best path between energy consumers and producers, in a graph with each link consisting of two nodes (ERs). The path with the lowest power losses is selected among the available paths. This paper presents a novel distributed power routing algorithm inspired by the Q-learning approach with both low computational cost and reduced communication overhead. This algorithm is validated through a comparative study with various power routing techniques, including the shortest path algorithm, graph traversal algorithm, and metaheuristic algorithms. Through MATLAB simulation, the performance of these algorithms is analyzed based on the power losses and computational effort.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"431 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115933503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If a fault does occur, the maintenance team is usually quick to arrange corrective maintenance to repair the equipment, as a generator shutdown can lead to huge financial losses. This prompt response limits the amount of faulty data. Furthermore, the equipment is made for industrial use and cannot be used for testing, so it is not possible to implement faults to create faulty bench tests. As a result, there is a lack of faulty signals for large hydrogenerators that are necessary to train artificial intelligence algorithms to diagnose faults. This work presents a method to augment and complete a balanced faulty database. The proposed method consists of generating faulty synthetic signals based on in-situ stray flux measurements and fault signatures deduced from simulated signals. To compute external magnetic flux in healthy and faulty cases, a 2D finite element model of a 370M VA salient-pole synchronous generator was created, validated, and used to extract field winding short circuit fault signatures of several severities.","PeriodicalId":137094,"journal":{"name":"2023 6th International Conference on Renewable Energy for Developing Countries (REDEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123331932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
