Synthetic Time Series PV Data with Real-World Physical Challenges and Noise for Use in Algorithm Test and Validation Primer Data set developed by NREL For more information please see publication at: https://www.nrel.gov/docs/fy23osti/86459.pdf simulation_metadata.csv Details concerning each site used for the simulated data study. Field | Units --------------------|------------------------------ id_number | Serial integer identifying the simulation. Matches the time series data filenames. lat | Decimal degrees - Latitude coordinate of the simulation’s location lon | Decimal degrees - Longitude coordinate of the simulation’s location name | Name of simulation’s location is_dry | boolean - Whether the simulation is treated as | western or eastern for soiling and noise assumptions | (if True, the system is treated as western) ilr | Inverter Loading Ratio (a.k.a. DC/AC ratio) rd_percent_per_year | %/year Assumed degradation rate tracking | boolean - Whether the simulated system is tracking or fixed tilt | (if True, the system is treated as tracking) array_tilt | numeric degrees For fixed-tilt systems, the array tilt from horizontal | (blank when tracking is True) sensor_tilt | numeric degrees For fixed-tilt systems, the irradiance sensor tilt from | horizontal (blank when tracking is True) calendar_years | list - List of calendar years spanned by dataset string_outages | boolean - Whether the simulation includes any string outages | (if True, string outages are included) pollen_soiling | boolean - Whether the simulation includes the effect of pollen soiling | (if True, pollen soiling is included) noise_parameters | char - Name of the system from Table 2 used for artificial noise Each zip file maked data_xxx-yyy contains: png image files of the associated data file xxx-yyy These are plots of the performance index plotted from each of the daily files along with a subplot that shows a daily time series of the various issues built into the given synthetic data set. csv daily files numbered from xxx-yyy These files contain all the columns from the 15-minute files (taken as daily averages of the 15-minute values and therefore same units) Field | Units ----------------------------------------|---------- actual power | W reference power | W pexp (array tilt) | W pexp (misaligned tilt) | W poa irradiance (array tilt) | W/m^2 poa irradiance (misaligned tilt) | W/m^2 ambient temperature | C ghi | W/m^2 wind speed | m/s data outage | boolean - Missing data indicator (1=missing, 0=not missing) pollen soiling | Soiling ratio for pollen-based soiling (1.0=no soiling loss) conventional soiling | Soiling ratio for sawtooth soiling (1.0=no soiling loss) string outages | Fraction of online DC capacity (1.0=no string outage) curtailment | Fraction of allowed AC capacity (1.0=no curtailment) tracker stall | boolean - Tracker stall indicator (1=tracking, 0=stall) clipping | boolean - Inverter clipping indicator according to the geometric clipping filter (1=clipping, 0=not clipping) poa insolation Wh/m2 (array tilt) | Wh/m2 poa insolation Wh/m2 (misaligned tilt) | Wh/m2 total rainfall mm | mm Each file titled interval_xxx-yyy represents These files provide 15 minute data as described below: (the table also provides units and cases where no units are listed the columns are unitless) Field | Units ------------------------------------|---------- actual power | W reference power | W pexp (array tilt) | W pexp (misaligned tilt) | W poa irradiance (array tilt) | W/m^2 poa irradiance (misaligned tilt) | W/m^2 ambient temperature | C ghi | W/m^2 wind speed | m/s data outage | boolean - Missing data indicator (1=missing, 0=not missing) pollen soiling | Soiling ratio for pollen-based soiling (1.0=no soiling loss) conventional soiling | Soiling ratio for sawtooth soiling (1.0=no soiling loss) string outages | Fraction of online DC capacity (1.0=no string outage) curtailment | Fraction of allowed AC capacity (1.0=no curtailment) tracker stall | boolean - Tracker stall indicator (1=tracking, 0=stall) clipping | boolean - Inverter clipping indicator according to the geometric clipping filter (1=clipping, 0=not clipping)
