Load curves modelling using algebraic polynomials

This paper proposes modelling ranked load curves using algebraic polynomials. Starting from the assumption of some characteristic parameters of load profiles: maximum power, minimum power and the energy consumption in a time period, characteristic coefficients of different types of algebraic polynomials such as: linear, parabolic and third-order are obtained. The modelling of real load profile has been tested on a small industrial consumer. For testing the modelling accuracy average power and the mean square power has been considered.
