This paper presents a study on different method of modeling the network reconfiguration problem to take into account load variation during a period of time. This work aim to determine if optimization process needs to take into account this fact in order to be used by a real distribution network operator. It presents a way to optimize an integer objective function.The optimization problem of type Mixed Integer Quadratic Constrained Program (MIQCP) and Mixed Integer Non-Linear Program (MINLP) is presented. Three different process of optimization on a define period are presented, two avoiding the use of power flow calculation and one using it. Methods are computed using ***three*** different load scenarios on the famous Baran & Wu test case. And results tends to show that it is not useful to take into account load variation and worst case optimization is the best method.
