forecast_CH_PeEn: Do complete-history persistence ensemble forecast

In kdayday/solarbenchmarks: Intra-Hour and Intra-Day Probabilistic Solar Forecast Benchmarks

Description

Generates a CH-PeEn forecast using all clear-sky indices at the same hour of day, for both intra-hourly and hourly-resolution forecasts. The clear-sky index ensemble is multiplied by the forecast clear-sky GHI to get a GHI ensemble, which is transformed to a full probabilistic forecast through an empirical CDF.

Usage

forecast_CH_PeEn(GHI, percentiles, sun_up, clearsky_GHI, ts_per_hour)

Arguments

GHI	A [day x time] matrix of the telemetry
percentiles	A vector of the percentiles corresponding to the desired forecast quantiles
sun_up	A [day x time] matrix of logicals, indicating whether the sun is up
clearsky_GHI	a [day x time] matrix of clear-sky irradiance estimates
ts_per_hour	Time-steps per hour, e.g., 12 for a 5-minute resolution forecast

Details

Valid for both intra-hourly and hourly-resolution forecasts. This function is for hindcasting only, and uses the same clear-sky GHI estimates for both the historical and forecast values.

Value

a matrix of quantile forecasts at each valid time in the input data
