text: The realization of a carbon-neutral civilization, which has been set
as a goal for the coming decades, goes directly hand-in-hand with the need for
an energy system based on renewable energies (REs). 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.

text: 'The market for microinverters is growing, especially in Europe. 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.'

text: This paper provides a hybrid energy system model created in Matlab/Simulink
which is based on photovoltaics as its main energy source. The model includes
a hybrid energy storage which consists of a short-term lithium-ion battery and
hydrogen as long-term storage to ensure autonomy even during periods of low PV
production (e.g., in winter). 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.

text: Due to failures or even the absence of an electricity grid, microgrid
systems are becoming popular solutions for electrifying African rural communities.
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.

text: "Access to precise meteorological data is crucial to be able to plan and install
renewable energy systems \r\nsuch as solar power plants and wind farms. In case
of solar energy, knowledge of local irradiance and air temperature \r\nvalues
is very important. For this, various methods can be used such as installing local
weather stations or using \r\nmeteorological data from different organizations
such as Meteonorm or official Deutscher Wetterdienst (DWD). An \r\nalternative
is to use satellite reanalysis datasets provided by organizations like the National
Aeronautics and Space \r\nAdministration (NASA) and European Centre for Medium-Range
Weather Forecasts (ECMWF). In this paper the \r\n“Modern-Era Retrospective analysis
for Research and Applications” dataset version 2 (MERRA-2) will be presented,
\r\nand its performance will be evaluated by comparing it to locally measured
datasets provided by Meteonorm and DWD. \r\nThe analysis shows very high correlation
between MERRA-2 and local measurements (correlation coefficients of 0.99) \r\nfor
monthly global irradiance and air temperature values. The results prove the suitability
of MERRA-2 data for \r\napplications requiring long historical data. Moreover,
availability of MERRA-2 for the whole world with an acceptable \r\nresolution
makes it a very valuable dataset."

text: "Efficiencies and energy yields of microinverters available on the market
during 2014‒2021 have been \r\nmeasured, compared, and ranked. Conversion efficiencies
as a function of load have been measured indoors with high \r\naccuracy and ranked
according to Euro- and CEC weightings. Energy yields have been measured outdoors
via \r\nidentical and calibrated crystalline silicon PV modules of 215 Wp (until
2020) and 360 Wp (starting 2021). Inverters \r\nwith two inputs have been fed
by two of those modules. DC input, AC power output and energy yield of each micro\x02inverter
have been recorded by individual calibrated electricity meters. CEC and EU efficiency
rankings have been \r\ncomputed and compared. To assess the influence of PV module
size, two extremes have been investigated: A rather \r\nsmall module with 215
Wp - as it has been used 10 years ago, and a brand-new module (2021) offering
360 Wp. Both \r\ntypes of modules contain 60 solar cells in series connection.
Appling the low-power modules, the challenge for the \r\ndifferent micro-inverters
has been during weak-light conditions, using the high-power modules, some inverters
\r\ntemporarily reach their power limits and yield is reduced. A method using
a reference configuration of inverter & \r\nmodule and a linear equation y = ax
+ b resulting in the actual yield, any module & inverter configuration can be
\r\ncharacterized by just the coefficients a and b."

text: Fast-growing energy demand of the world makes the researchers focus
on finding new energy sources or optimizing already-developed approaches. 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.

text: "With its growing population and industrialization, DREs, and solar technologies
in particular, provide a \r\nsustainable means of bridging the current energy
deficit in Africa, increasing supply reliability and meeting future \r\ndemand.
Data acquisition and data management systems allow real time monitoring and control
of energy systems as \r\nwell as performance analysis. However commercial data
acquisition systems often have cost implications that are \r\nprohibitive for
small PV systems and installations in developing countries.\r\nIn this paper,
a multi-user, multi-purpose microgrid database system is designed and implemented.
MAVOWATT \r\n270 power quality analyzers by GOSSEN METRAWATT, raspberry pi modules
and sensors are used for measuring, \r\nrecording and storing electrical and meteorological
data in East Africa. Socio-economic data is also stored in the\r\ndatabase. The
designed system employs open source software and hardware solutions which are
best suited to \r\ndeveloping regions like East Africa due to the lower cost implications.\r\nThe
expected results promise a comprehensive database covering different electro-technical
and socio-economic \r\nparameters useful for optimal design of microgrid systems."

text: " Efficiencies and energy yields of microinverters available on the market
during 2014‒2020 have been \r\nmeasured, compared, and ranked. Conversion efficiencies
as a function of load have been measured indoors with high \r\naccuracy and ranked
according to Euro- and CEC weightings. Energy yields have been measured outdoors
via \r\nidentical and calibrated crystalline silicon PV modules of 215 Wp each.
Inverters with two inputs have been fed by \r\ntwo of those modules. DC input,
AC power output and energy yield of each micro-inverter have been recorded by
\r\nindividual calibrated electricity meters. Apparently, some inverters have
been optimized for high irradiance levels \r\nand ranked better at the CEC efficiency
ranking, others performed very well also at low irradiance levels, thus \r\nranking
higher at in the EU efficiency ranking. Efficiency ranks are slightly deviating
from rankings by energy yield \r\nmeasurements. At one inverter, a slow MPPT algorithm
that barely could follow quickly changing irradiance levels is \r\nmost probably
responsible for this effect. Another inverter switched off for a while after operation
at high power, \r\nanother one failed permanently. Apparently, some inverters
are been optimized to show excellent datasheet ratings \r\nfor EU- or CEC- efficiency.
On the other hand, two inverters (each featuring two inputs) did not show an outstanding
\r\nperformance at the EU- and CEC-ratings but achieved leading ranks for AC energy
yields. For the customer, AC \r\nyield is a major performance indicator of a microinverter
and should be included in the datasheet."

text: "To provide a simple instrument to operate residential Load-Shifting or Demand-Side-Management
\r\nsystems, the measurement of the actual grid frequency seems to be an appropriate
method. 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"
