As an example nowadays, voltage source converters (VSC) are extensively utilized as the interface between DC energy sources and the power system. Photovoltaic (PV) inverters have emerged as one of the most indispensable and widely utilized components in smart grid operations. Considering the complexity, costliness, and possible ineffectuality of PEI conventional manual tuning processes, an automated controller self-tuning approach has been proposed through harnessing the capabilities of particle swarm optimization (PSO), a heuristic optimization method. The multi-megawatt solar PV-plant has been connected to a benchmark two-area four-machine power system. The entire system is simulated using a real-time digital simulator (RTDS). The solar PV plant enhanced performance in conjunction to both improved steady-state and dynamic operation of each of its voltage source inverters (PV-VSI) concludes the effectiveness and benefits of the proposed tuning approach. This enables smoother renewable energy integration, reliable delivery of energy at a lower cost, and further reduced carbon footprints worldwide.","PeriodicalId":177444,"journal":{"name":"2016 IEEE PES PowerAfrica","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124490834","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}

Possibilities for leveraging these smart grid tools in the developing world are being explored, particularly with emerging microgrids for rural electrification. In these off-grid systems, smart meters at the residential level are being used to manage the delivery of affordable electricity through novel uses of mobile payments and direct demand-side control at the customer level. In contrast to traditional power systems in the developed world, the available total supply in microgrids, which can incorporate multiple types of generation, is not always sufficient to meet the aggregate demand, even under normal operating conditions. Moreover, both the available supply and the demand are highly variable, limiting the value of deterministic analyses. This paper introduces a simulation tool for assessing the performance of these systems using probabilistic models of supply and demand. A key feature of the tool is the use of stochastic models for the individual loads and supplies, which are aggregated precisely to obtain stochastic models of the system-level behavior. This makes it possible to evaluate and compare system performance for different operating and business strategies that take advantage of the capabilities for fine-grained control. The paper describes the simulator inputs, computations and illustrative results for a case study.","PeriodicalId":177444,"journal":{"name":"2016 IEEE PES PowerAfrica","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133679857","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}

Specifically, the interest around integrating islanded buildings with renewable energy sources (RES) in addition to the conventionally used diesel generators has grown recently. Obviously, various “Microgrids” are already utilized all over the world for different purposes. In this respect, this work proposes an online Energy Management System (EMS) of an islanded hybrid PV-Battery-Diesel microgrid, while keeping efficient operation conditions of each microgrid component. Indeed, the proposed EMS gives the priority of power supply to RES, however, the battery is essential to assist as a backup power source in case of power outage and to ensure stable operation of the whole system. The Diesel Generator Set (GenSET) is operated in case of low state of charge (SOC) and insufficient generation by RES. A case study of a hospital complex in the Middle East region is chosen to conduct this work. Different operation scenarios with respect to the fuel consumption are considered and the results are listed. Simulation results indicate significant fuel savings in addition to reduction in the total operation time of the diesel GenSET.","PeriodicalId":177444,"journal":{"name":"2016 IEEE PES PowerAfrica","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131309666","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}

Electricity can no longer be considered a luxury, and is necessary for maintaining a modern life expectancy. This paper explores the feasibility of energy production and storage across South America, South East Asia and sub-Saharan Africa with National Renewable Energy Lab's Geospatial Toolkit and the integrated HOMER interface. Multiple scenarios are constructed based on different community sizes with relative demand and load profiles. Optimization techniques are used to value both traditional generation options (diesel generation), their renewable counterparts (wind and solar), as well as energy storage methods (batteries). Each analysis is based on location-specific irradiance, wind speeds, and fuel prices. Economics remain at the forefront, as a community's ability to purchase the generated power is the centerpiece of this entire investigation. With all three regions in a similar state of development, parallels can be drawn among them. By scrutinizing data from all three continents, similarities can be observed between population density and distribution, their demand and usage of electricity, and purchasing power parity. These similarities can be used to fill gaps in our understanding of how a community may use generated electricity, or how that demand will change over time. This is instrumental in scaling renewable energy based microgrids globally.","PeriodicalId":177444,"journal":{"name":"2016 IEEE PES PowerAfrica","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126161032","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}
