+Illuminator documentation
+=========================
+
+The Illuminator is an easy-to-use Energy System Integration
+Development kit to demystify energy system operation, illustrate challenges
+that arise due to the energy transition and test
+state-of-the-art energy management concepts. we utilise Raspberry Pis
+as the individual components of the energy system emulator,
+and the simulation engine is based on `Mosaik.

The PV data is obtained from the Meteonorm software, and solar radiation and positioning values were obtained for the region
+of Rotterdam. With the new updates, it was possible to extract 15-minute interval data from within
+meteonorm. The input data and parameter setting for PV models are through the ‘.csv’ or ‘.txt’ file in the Scenario
folder
+and the file ‘buildmodelset.py’ in the configuration folder. The input data from ‘.csv’ or ‘.txt’ file are as follows,
`G_Gh'GHI global horizontal irradiance
+`G_Dh'DHI direct horizontal irradiance
+`G_Bn': DNI direct normal irradiance
+`Ta`: temperature
+`hs`: elevation of the sun
+`FF`: wind speed
+`Az`: azimuth of the sun
+
The parameters set in the python file are shown as follows,
+'Module_area': module area. available in the spec sheet of a PV module
+'NOCT': module temperature under the standard test conditions (STC) and stands for Nominal Operating Cell Temperature
+'Module_Efficiency'
+'Irradiance_at_NOCT': W/m2 This is the irradiance that falls on the panel under NOCT conditions
+'Power_output_at_STC': Watts. Available in the spec sheet of a module
+'m_tilt': module tilt angle
+'m_az': azimuth of the module
+'cap': capacity
+'output_type': power or energy
+
Calculating the irradiance on a module at a specific location is essential to calculate the output of +a PV system, and is governed by multiple factors. Irradiance is the incoming power of +solar radiation over a unit area and is measured in W/m2. Due to the rotation and revolution of the +earth, the position of the sun is not constant. Hence, the amount of irradiation received changes +continuously with the time of day, month, and year. Location on the earth also factors in for the amount of +irradiance received. Due to the changing elevation and azimuth angle of the sun throughout the day, +the incoming solar radiations are not normal to the surface. The angle between the normal surface and the solar radiation is called the Angle of Incidence (AOI), and it affects the amount of irradiance of the module surface. The equation +to calculate the AOI is shown below.
+cos_aoi = cos(90 - m_tilt)) * cos(hs) * cos(m_az - Az) + sin(90 - m_tilt)) * sin(hs)
+
For testing the PV modules during manufacturing and calculating the output from a module over a while, some standard test conditions (STC) have been defined, according to which we have AM1.5 spectrum as standard with an irradiance of 1000 W/m2. The attenuation of solar radiation upon entering the earth is because of scattering and absorption by dust particles, +aerosols in the atmosphere, and air molecules. The presence of water vapor, oxygen, and carbon dioxide are significant +contributors to the absorption of radiation. Because of this attenuation, the incoming radiation breaks into a diffused component, +called Diffused Horizontal Irradiance (DHI) and a direct component of light, called Direct Normal Irradiance (DNI). +There is another component of the radiation that falls on the module surface, and that is the reflected component which is +because of the reflected radiations from the surface around the module. This is called Global Horizontal irradiance (GHI). +Meteorological stations measure the DHI and DNI and GHI can be calculated using the following formula where albedo ranges between 0.05 - 0.20 for urban environments, +0.05 - 0.10 for forests and 0.60 for snow. The following formulas are used to calculate the irradiance using the DHI, DNI, and GHI.
+svf = (1 + cos(m_tilt)) / 2
+g_diff = svf * G_Dn # svf is Sky View Factor
+g_ref = albedo * (1 - self.svf) * G_Gh #albedo is the Albedo value 0.2
+g_dir = G_Bn * cos_aoi
+g_all=g_diff+g_ref+g_dir
+
Changing module temperature hurts the output of the module. Wind speed and the mounting height of the panel from the ground impact the module temperature. Blowing wind decreases the temperature due to convective heat transfer, and mounting above the ground makes enough space for heat to dissipate from the module and for its interaction with the blowing wind. +The Duffie-Beckman model covers these factors while calculating the module temperature.
+m_temp = Ta + (g_all/ Irradiance_at_NOCT)) * (NOCT - 20) * (9.5/(5.7 + 3.8*FF))) * (1 - Module_Efficiency / 0.90))
+
The module manufacturer provides it to give an estimate of average cell temperature. Instead of individual values of T and a, for silicon-based solar cells, T ∗ a +is taken as 0.9.
+efficiency = Module_Efficiency * (1 + (-0.0035 * (m_temp - 25)))
+P_AC=cap * sf/P_STC*m_area*g_all*efficiency*inv_eff*mppt_eff*losses
+
+
Wind data chosen is from an on-shore site situated in The Netherlands at 100m at 5 minutes intervals.
+The input data and parameter setting for Wind models are through the ‘.csv’ or ‘.txt’ file in the Scenario
folder
+and the file ‘buildmodelset.py’ in the configuration folder. The input data from ‘.csv’ or ‘.txt’ file is the wind speed ‘u’.
+The parameters set in the python file are shown as follows,
'p_rated': kW power it generates at rated wind speed and above
+'u_rated': m/s #windspeed it generates most power at
+'u_cutin': m/s #below this wind speed no power generation
+'u_cutout': m/s #above this wind speed no power generation. Blades are pitched
+'cp': coefficient of performance of a turbine. Usually around0.40. Never more than 0.59
+'diameter': Wind turbine rotor diameter
+'powerout': output power at wind speed u

There are three methods to configurate the cases.
+You can use the provided config.xml
and connection.xml
files in the Cases/
directory.
+We provide four example in Cases
folder:
Residential Case study(ResidentialCase
)
Multienergy system case study(MultienergyCase
)
Electricity market game case study (GameCase
) For more information about the electricity market case study, you can reference the Msc thesis, and
Distribution voltage control case study (DNcontrolCase
) .
The config.xml
file is used to define the models in the case and where to
+run the model.
+For example in the config.xml
below, we built a simulation with only Wind and PV models.
+In the configuration below, the wind model runs (localy? in the master?) and the PV model runs in a client with IP ‘192.168.0.1’, and the master get the PV model’s information from the port the client’s port 5123
.

The connection.xml
file sets how the message are transfered from one model to others.
+For example in the snippet below, the ctrl
model sends information about ‘flow2e’ to electrolyser
to control its hydrogen generating speed.
+The electrolyser
send the ‘h2_gen’ information to model h2storage
‘h2_in’ to control the hydrogen storing speed.

Run the simulation creator_**.py
to create and run the simulation based on the provided case and scenario.
+To see the results via the dashboard, you need Internet and sign up in wandb software.
+The simple_test.py
shows a simple case with the configuration inside of the file.
Four case studies show how to use Illuminator, and to verify the Illuminator’s performance.
+The first demo shows a residential energy community system which include Households,
+PV panels, Wind generators, Battery and Hydrogen system
+to achieve electric power self-sufficiency.
+The controller’s algorithm in this case runs in the master RasPi Controllers/ResidentialController
, and
+the rest client simulators are separately deployed in different
+RasPis. The data flow between the simulators (clients) is also shown in
+the figure below. Based on the inputs, including the generated power
+from PV and Wind, the consuming power of households, and
+the state of charge (Soc) of the Battery and Hydrogen, the
+controller decides the power from the Battery and Fuel cell
+and the power to the Electrolyser.
In the case study, we use
+simple logic to achieve self-sufficiency. If Battery has enough
+capacity for charging or discharging to achieve power balance,
+use the Battery first. If Battery doesn’t have enough capacity
+to achieve power balance, then use Electrolyser or Fuel cell
+to achieve power balance. All the input data are in the Scenarios/
directory and all the output data are in file Result/ResidentialCase/
.
The second demo shows the Multi-carriers energy system, which incorporate the electricity +network, hydrogen network and heat network. All the energy assets are shown in the below figure.
+The third demo shows the electricity trade game and more details please refer to this Msc thesis
+The fourth demo shows the voltage control in the CIGRE LV voltage network. The network model is in the Models/EleDisNetworkSim/
directory, and the control method is in Controllers/NetVoltageControllerSim/
