“…The array of all k pv values is formed according to described method, and its statistical analysis produced mean value of k pv =0.83 and its range as 0.00÷1.66. For analysed load, k pv =0.76 is found in [30]. Thus, mean value obtained by the presented method differs from the available literature value for less than 10%.…”

“…For reactive power, presented method yields mean value and relatively wide range of k qv : 1.8 and -0.58÷4.18, respectively. The deviation from mean value of 1.68 given in [30] is around 7%, justifying again equal parameter weighting for both real and reactive power in the case of aggregate commercial load model. The method is also applied using only the average values of the parameter sets, instead of the multiple equally-weighted sets.…”

“…Described aggregation method is also applied to the UK commercial load, for which average daily load curve is presented in [30]. The maximum loading occurs during working hours, at 11:30 a.m., when the load composition with respect to real power demand is: SMPS a_PFC 19.2 %, SMPS p_PFC %, SMPS no_PFC 2.5 %, SPIM RSIR_CT 2.3 %, CSR CT 3.3 %, 3PIM_CT 1 %, 3PIM drive 8.8 %, resistive load 22.5 %, LFL 18.3 %, HID 1 %, CFL 10.8% and LED 5.3 %.…”

“…In [30], parameters of linear fluorescent lamps (LFLs) and some high intensity discharge (HID) lamps are provided, noting that these lamps are predominantly used in commercial and industrial load classes. Thus, k pv and k qv of LFL are 1.88 and 3.90, while these parameters of HID lamp are 0.94 and -1.47, respectively.…”

This paper presents parameter values and ranges of static load models used in power system analysis for the representation of both individual electrical devices and aggregate system loads. The paper discusses and correlates load models and their parameters following statistical processing of the responses of around 100 transmission system operators and utilities around the world, who participated in a survey initiated by CIGRE Working Group C4.605, with the corresponding information on load models and their parameter values from the existing literature. According to the survey, the most frequently used static load models are voltage dependent, and voltage and frequency dependent exponential load models. The identified typical parameter values and ranges of these static load models, both for low voltage devices and for aggregate loads at higher voltage levels, are results of the analysis of a large number of data. Based on these results, the paper provides recommendations for their further use in power system studies and also introduces a novel method for obtaining the mean values and ranges of parameters of the aggregate system load models. Index Terms-Load class, load modelling, load parameter, power system analysis, static load model. I. INTRODUCTION HERE are two general methodologies for load modelling: component-based and measurement-based approaches [1]. The first one assumes a priori knowledge as to what electrical device, i.e. load component, is to be modelled and represented with adequate load model(s) and corresponding load model parameters, while the second fits assumed load model to available measurement data. Numerous static and dynamic load models for quantifying real and reactive power responses to voltage and frequency variations are already developed.

“…In this work, authors also introduced an influence of changing power operating mode on resulting harmonic emission levels as well as gave an important remark to test modern PE in presence of non-sinusoidal supply voltage waveform. This modelling approach in combination with probabilistic methods was also applied in [10] for studies of the commercial load sector.…”
