The power generation and load data in the case studies of the paper "Modeling, Prediction, and Risk Management of Distribution System Voltages with Non-Gaussian
Probability Distributions".
The active power outputs of photovoltaic units are obtained using the actual solar irradiation data provided by SolarAnywhere [1]. The load data are obtained by normalizing the load drawn from real-world measurements [2], and then multiplying it by the average load from the original load data of the systems [3], [4].
The modified IEEE 33-bus system contains 4 PV units and 32 loads. The nominal power generation of each PV unit is 1 MW and the average load of each bus is found in [3].
The modified IEEE 123-bus system contains 9 PV units and 85 loads. The nominal power generation of each PV unit is 0.8 MW and the average load of each bus is found in [4].
".mat" type of Matlab.
"IEEE33_PV&Load_Data.mat' is the data file in the modified IEEE 33-bus system.
"IEEE123_PV&Load_Data.mat' is the data file in the modified IEEE 123-bus system.
"PV_hourly_normalized" is the hourly data of the normalized active power of PV units, of which each column represents a PV unit. The base value for the normalization of each PV unit is the nominal power generation of each PV unit.
"load_hourly_normalized" is the hourly data of the normalized loads, of which each column represents a load. The base value for the normalization of each load is the average value of each load.
"timeLabel_hourly" is the time label of the hourly data from Jan. 1, 2011 to Dec. 31, 2014.
