Due to the strong weather-related, daily, and seasonal fluctuations in supply of REs, suitable energy storage devices must be included for such energy systems. For this purpose, an energy system model featuring hybrid energy storage consisting of a hydrogen unit (for long-term storage) and a lithium-ion storage device (for short-term storage) was developed. With a proper design, such a system can ensure a year-round energy supply by using electricity generated by photovoltaics (PVs). In the energy system that was investigated, hydrogen (H2) was produced by using an electrolyser (ELY) with a PV surplus during the summer months and then stored in an H2 tank. During the winter, due to the lack of PV power, the H2 is converted back into electricity and heat by a fuel cell (FC). While the components of such a system are expensive, a resource- and cost-efficient layout is important. For this purpose, a Matlab/Simulink model that enabled an energy balance analysis and a component lifetime forecast was developed. With this model, the results of extensive parameter studies allowed an optimized system layout to be created for specific applications. The parameter studies covered different focal points. Several ELY and FC layouts, different load characteristics, different system scales, different weather conditions, and different load levels—especially in winter with variations in heating demand—were investigated.</jats:p>"}],"publication":"Hydrogen","type":"journal_article","doi":"10.3390/hydrogen4030028","title":"Investigation of Different Load Characteristics, Component Dimensioning, and System Scaling for the Optimized Design of a Hybrid Hydrogen-Based PV Energy System","volume":4,"author":[{"last_name":"Möller","full_name":"Möller, Marius Claus","id":"72391","first_name":"Marius Claus"},{"last_name":"Krauter","orcid":"0000-0002-3594-260X","full_name":"Krauter, Stefan","id":"28836","first_name":"Stefan"}],"date_created":"2025-04-09T12:08:15Z","date_updated":"2025-04-09T12:09:46Z","publisher":"MDPI AG","intvolume":"         4","page":"408-433","citation":{"apa":"Möller, M.

Driven by the strongly rising prices for electricity, many small photovoltaic energy systems are being installed. Since monitoring for these plants is often quite costly, their yields are often not logged. Since 2014, microinverters have been studied at the University of Paderborn. The investigations are divided into indoor and outdoor tests. In the indoor area conversion efficiencies as a function of load have been measured with high accuracy and ranked according to Euro- and CEC weightings. In the outdoor laboratory, the behavior in the real world is tested. Energy yields have been measured outdoors via identical and calibrated crystalline silicon PV modules. Here, the investigations were carried out with modules of the power of 215 Wp until the year 2020. Because of the increasing module power nowadays, modules with an output of 360 Wp are now being used. To assess the influence of PV module size, two extremes have been investigated: A rather small module with 215 Wp - as it has been used 10 years ago, and a brand-new module (2021) offering 360 Wp. Both types of modules contain 60 solar cells in series connection. Appling the low-power modules, the challenge for the different micro-inverters has been during weak-light conditions, using the high-power modules, some inverters temporarily reach their power limits and yield is reduced. A method using a reference configuration of inverter & module and a linear equation resulting in the actual yield, any module & inverter configuration can be characterized by just the two coefficients."}],"status":"public","_id":"32334","user_id":"16148","department":[{"_id":"53"}],"language":[{"iso":"eng"}]},{"_id":"32333","department":[{"_id":"53"}],"user_id":"16148","language":[{"iso":"eng"}],"publication":"Proceedings of the 49th IEEE Photovoltaic Specialists Conference","type":"conference","abstract":[{"text":"This paper provides a hybrid energy system model created in Matlab/Simulink which is based on photovoltaics as its main energy source.

The sectors heat and electricity are coupled by using the waste-heat generated by production and reconversion of hydrogen through an electrolyser respectively a fuel cell. A heat pump has been considered to cover the residual heat demand (for well insulated homes). Within this paper a model of the space heating system as well as the hot water heating system is presented. The model is designed for the simulation and analysis of a whole year energy flow by using a time series of loads, weather and heat profiles as input. Moreover, results of the energy balance within the energy system by simulation of a complete year by varying the orientation (elevation and azimuth) of the PV system and the component sizing, such as the lithium-ion battery capacity, are presented. It turned out that a high amount of heating energy can be saved by using the waste heat generated by the electrolyser and the fuel cell. The model is well suited for the analysis of the effects of different component dimensionings in a hydrogen-based energy system via the overall energy balance within the residential sector.","lang":"eng"}],"status":"public","date_updated":"2022-07-11T06:59:25Z","date_created":"2022-07-08T07:49:53Z","author":[{"first_name":"Marius Claus","last_name":"Möller","full_name":"Möller, Marius Claus","id":"72391"},{"first_name":"Stefan","full_name":"Krauter, Stefan","id":"28836","orcid":"0000-0002-3594-260X","last_name":"Krauter"}],"title":"Model of a Self-Sufficient PV Home using a Hybrid Storage System based on Li-Ion Batteries and Hydrogen Storage with Waste Heat Utilization ","conference":{"name":"49th IEEE Photovoltaic Specialists Conference","start_date":"2022-06-05","end_date":"2022-06-10","location":"Philadelphia, PA, USA"},"year":"2022","corporate_editor":["IEEE"],"citation":{"apa":"Möller, M.

However, they are heavily stressed and complex to control due to their intermittency and demand growth. Demand side management (DSM) serves as an option to increase the level of flexibility on the demand side by scheduling users’ consumption patterns profiles in response to supply. This paper proposes a demand-side management strategy based on load shifting and peak clipping. The proposed approach was modelled in a MATLAB/Simulink R2021a environment and was optimized using the artificial neural network (ANN) algorithm. Simulations were carried out to test the model’s efficacy in a stand-alone PV-battery microgrid in East Africa. The proposed algorithm reduces the peak demand, smoothing the load profile to the desired level, and improves the system’s peak to average ratio (PAR). The presence of deferrable loads has been considered to bring more flexible demand-side management. Results promise decreases in peak demand and peak to average ratio of about 31.2% and 7.5% through peak clipping. In addition, load shifting promises more flexibility to customers.</jats:p>","lang":"eng"}],"status":"public","publication":"Energies","type":"journal_article","title":"Neural Network-Based Demand-Side Management in a Stand-Alone Solar PV-Battery Microgrid Using Load-Shifting and Peak-Clipping","doi":"10.3390/en15145215","date_updated":"2024-10-17T08:46:23Z","publisher":"MDPI AG","volume":15,"date_created":"2023-10-11T08:13:13Z","author":[{"last_name":"Philipo","id":"88505","full_name":"Philipo, Godiana Hagile","first_name":"Godiana Hagile"},{"first_name":"Josephine Nakato","last_name":"Kakande","full_name":"Kakande, Josephine Nakato","id":"88649"},{"last_name":"Krauter","orcid":"0000-0002-3594-260X","full_name":"Krauter, Stefan","id":"28836","first_name":"Stefan"}],"year":"2022","intvolume":"        15","citation":{"apa":"Philipo, G.

For an efficient use of solar and wind energy in an energy system, correct design and sizing of a power system is of high importance and improving or optimizing the process of data obtaining for this purpose leads to higher performance and lower cost per unit of energy. It is essential to have the most precise possible estimation of solar and wind energy potential and other local weather parameters in order to fully feed the demand and avoid extra costs. There are various methods for obtaining local data, such as local measurements, official organizational data, satellite obtained, and reanalysis data. In this paper, the Modern-Era Retrospective analysis for Research and Applications dataset version 2 (MERRA-2) dataset provided by NASA is introduced and its performance is evaluated by comparison to various locally measured datasets offered by meteorological institutions such as Meteonorm and Deutscher Wetterdienst (DWD, or Germany’s National Meteorological Service) around the world. After comparison, correlation coefficients from 0.95 to 0.99 are observed for monthly global horizontal irradiance values. In the case of air temperature, correlation coefficients of 0.99 and for wind speed from 0.81 to 0.99 are observed. High correlation with ground measurements and relatively low errors are confirmed, especially for irradiance and temperature values, that makes MERRA-2 a valuable dataset, considering its world coverage and availability.</jats:p>","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":3837152,"access_level":"closed","file_name":"energies-14-00882 Khatibi Krauter MERRA 2.pdf","file_id":"29177","date_updated":"2022-01-06T13:33:09Z","date_created":"2022-01-06T13:33:09Z","creator":"krauter"}],"oa":"1","date_updated":"2022-01-06T13:37:34Z","volume":14,"author":[{"id":"43538","full_name":"Khatibi, Arash","last_name":"Khatibi","first_name":"Arash"},{"last_name":"Krauter","orcid":"0000-0002-3594-260X","full_name":"Krauter, Stefan","id":"28836","first_name":"Stefan"}],"doi":"10.3390/en14040882","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/1996-1073/14/4/882/htm"}],"has_accepted_license":"1","publication_identifier":{"issn":["1996-1073"]},"publication_status":"published","intvolume":"        14","citation":{"ama":"Khatibi A, Krauter S.

Due to the present \r\ninflexibility and the lack of sufficient throttling capabilities of lignite and nuclear power plants, a surplus of \r\nelectricity generation occurs during periods of high wind and solar power generation. While the specific CO2-\r\nemission is decreasing then ‒ due to the increased share of Renewables, the grid frequency is increasing (to a certain \r\nlimit). Using the grid frequency as an indicator to switch-on and off certain loads (loads that do not require power \r\npermanently (e.g. dishwashers, washing machines, dryers, fridges and freezers, heaters) could provide a simple, \r\ninexpensive demand-side management indicator to lower specific CO2‒emssions and costs (if a dynamic \r\nconsumption tariff is available). To check the truthfulness of that hypothesis, the grid and frequency data of the \r\nGerman grid of the year 2018 have been collected and a the correlation between grid frequency, power surplus, share \r\nof renewables vs. CO2-contents and price at the European energy exchange (EEX) have been calculated. The results \r\nshow: Correlation between frequency and share of renewables is quite low (r = 0.155) due to the fact that primary \r\ngrid control quickly compensates deviations from the 50 Hz nominal frequency. There is a good anti-correlation (r = -\r\n0.687) between the EEX‒prices and the share of renewables in the grid. Over the years, correlation between \r\nelectricity trading prices (EEX) and CO2 emissions is quite good (r =0.665), within the one year (2018) that \r\ncorrelation almost doesn’t exist, possibly due to the inflexibility of the bulky lignite power plants that even operate at \r\nnegative prices. \r\n"}],"author":[{"first_name":"Stefan","orcid":"0000-0002-3594-260X","last_name":"Krauter","id":"28836","full_name":"Krauter, Stefan"},{"first_name":"L.","full_name":"Zhang, L.","last_name":"Zhang"}],"date_updated":"2022-01-06T12:42:22Z","conference":{"start_date":"2020-09-07","name":"37th European Photovoltaic Solar Energy Conference and Exhibition (EUPVSEC 2020)","location":"online","end_date":"2020-09-11"},"doi":"10.4229/EUPVSEC20202020-6BV.5.9","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["\t3-936338-73-6"]},"citation":{"mla":"Krauter, Stefan, and L.
