Abstract
This paper presents a technical analysis that shows the relevance of considering the ZIP model in the load flow problem applied to electric power distribution systems. The main objective of the analysis is to numerically evaluate the impact of this modeling in the solution of optimization problems traditionally addressed in the planning of power electrical systems. The mathematical analysis performed using the IEEE 118-bus theoretical network demonstrates that the technical losses and voltage profiles obtained in the optimal solution of the problem differ when three ZIP model scenarios are considered, which means that this approach should not be neglected in system planning and operation studies, since non-consideration of the ZIP model can bring impacts on the network diagnostic and consequently lead to imprudent investments from the perspective of the minimum overall cost required by ANEEL.
