The use of Mixture of Generalized Gaussian for trend analysis of the load duration curve: Summer and winter load variability in Tunisia

This paper proposes a probabilistic representation of load duration curve based on the use Mixture of Generalized Gaussian distribution (MGG) which uses eight physicals parameters connected to the load distribution. Based on these MGG parameters the trend evolution of the annual, winter and summer LDC were examined. Load data from the Tunisian Company of Electricity and Gas (STEG) have been used in this paper to investigate historical changes in LDC structure.
