The electricity production from renewables grew from around 6% in 2000 to nearly 36% in 2017. With the policy instrument feed-in-tariff, the PV installations boomed in the country over the past years, though the recent trend is in decline. Also in many other countries (e.g., China, Japan, etc.) solar PV installation is growing recently at a faster rate than many projected scenarios. It is seen as the next major energy regime in many countries. Hence it is necessary to model the future market growth and predict the further cost reductions under different scenarios of market dynamics. In this paper, using the experience curve model, the historical PV market trend is analyzed and results are used to predict the future of solar PV growth in German and global market, including its cost reduction potential. Also the solar PV policy of Germany has been discussed. As the results, the future PV growth scenarios are presented until 2030 for Germany and global cases. Based on the used experience curve model, the respective future price trends (2030 prices for German PV systems) are projected to be in a range from 250 to 500 €/kWp.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129689345","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 use of smart technologies can create added value such as lowering the energy costs by increasing energy efficiency in enterprises. While the topic of using digital and smart technologies for energy efficiency already plays an essential role in large enterprises, small and medium sized enterprises (SMEs) are still not aware of the topic in general as well as the benefits of investing in energy efficiency measures.This paper presents an application-oriented scientific approach of identifying the application potential of smart technologies for energy efficiency as well as energy- and load-management in SMEs. Due to the diversity of smart technologies which are actually offered on the market, a technology-screening classifies the different systems into specific categories. These categories are evaluated and assessed in a cross-system comparison regarding the application potential in SMEs. Based on onsite investigations in SMEs, the results show the practical application potential for each technology category according to specific criteria. According to these criteria, smart technologies can be used in different sections of the enterprise, which are also developed during onsite investigations. The key-findings of the onsite investigations will feed into the foreseen application test of smart technologies in SMEs, analysing technical, software-specific and socio-economic aspects of smart technologies close to and in dialogue with the stakeholders.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"520 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124483161","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}

An estimated 20% world’s population does not have access to electricity. Most of those people live in areas often difficult to connect to electrical grids. Renewable energy technologies might be lower cost options in such areas, where both population and electricity demand are low. The main objective of this study was to develop a reliable and cost competitive autonomous energy supply system with renewable energy resources. As a reference site, a University campus in northern Ghana was chosen. A tool for load profile assessment is developed. Resulting load profiles under different scenario are presented. Available renewable energy resources is estimated. Based on these results, a hybrid system has been sized and is later validated in HOMER Pro®. Results show an autonomous hybrid system configuration with 185 kWp PV, 73 kWh battery and three biodiesel (Jatropha based) generators (165 kVA, 110 kVA and 34 kVA) as optimum to supply the electricity need. Levelized cost of electricity (LCOE) was calculated as 28 €ct/kWh, 2 % lower than the grid electricity price. Sensitivity analysis showed the imputed interest rate, fuel price and investment costs have the most impact on LCOE.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133958360","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 aim is a 100% supply with renewable energies. This way, conventional electrical power generators will be replaced by decentralized power sources, which feed in power to the grid using electrical power converters. Rotating inertia and speed controllers used for the control of the power grid will disappear and must be replaced by a suitable control of the future grid devices. However, not only feed in devices may contribute to the grid control, but also electrical loads may contribute their part.In this publication options to use LED lamps as variable loads are investigated. As a comparison, the brightness of incandescent lamps (“light bulbs”) may vary approximately +/ 20% of their nominal power at +/ 10% of the nominal voltage. It is known that slow variations of the lamp brightness are not perceived by users. Here, suitable ramp rates are determined by a survey with a number of test persons in Köln, Germany, and Hong Kong. It turned out that the possible ramp rates and the possible power change, which are not perceivable, can be a significant fraction of the nominal lamp power, such that Primary Control Power and Fast Frequency Control might be provided with LED lamps.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133453486","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}

In addition to that it is possible to define soft and hard feed-in and acquisition constraints for the overall VPP energy schedule. To enable the VPP optimization and take into account these three different optimization levels, an accounting method which considers all internal and external usages of energy for each asset is introduced. The simulation results show that the optimization model can effectively find the economically best schedule by varying trading volumes, energy self-sufficiency of single users or exchange of energy within the VPP.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131344441","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}
