Properties of the mixed model equations for alternative implementations of factor-analytic models are discussed, and extensions to structured modelling of covariance matrices for multi-trait, multi-environment scenarios are described.
Specifically, the study examined the level of variability of peak demand in the period before and after implementation of power factor improvement schemes and assesses the likely impact of power factor improvement schemes on peak demand.
Specifically, the paper examines the variability of peak electricity demand in the periods before and after the implementation of power factor improvement schemes and assesses the likely impact of power factor improvement schemes on peak demand.
That is to examine the level of variability of peak demand in the period before and after implementation of power factor improvement schemes and to assess the likely impact of power factor improvement schemes on peak demand.
To supplement the boxplot analysis in understanding the variability of domestic peak demand in the period before and after implementation of power factor improvement schemes, a variance ratio test for domestic peak demand before and after implementation of power factor improvement schemes are estimated.
In this paper, the boxplot graph is used to compare the variability of domestic peak demand in the period before and after implementation of power factor improvement schemes.
A lower growth rate in peak demand after implementation of power factor improvement schemes compared to the period before implementation implies stable and normal growth in peak demand arising from expected growth in demand.
In this paper, the fractional polynomial graph is used to compare the growth rate of electrical peak demand in the period before and after implementation of power factor improvement schemes.
In the period of implementation of power factor correction scheme, there is a noticeable growth in consumption of electricity at nonpeak time of use (TOU) and slight slump in electricity consumption at peak TOU compared the period before the implementation of the scheme.
Finally, with the implementation of power factor correction scheme, there is a noticeable reduction in electricity consumption at peak time of use (TOU) and growth in consumption of electricity at nonpeak time TOU, which was not the case before the implementation of the scheme.
To analyze the growth and variability of domestic peak demand in the period before and after implementation of power factor improvement schemes, this paper employs the graphical descriptive analysis methods including the two-way fractional polynomial graph, the boxplot graph, and the analysis of variance.
