The development of electric vehicles (EVs) brings a lot of new problems from the point of view of the electrical grid. Electric vehicles (EV) charging causes an impact load on the distribution grid, which is often non-symmetrical, and can reach high levels in relevant parts of the grid. This leads to deterioration of the electrical energy parameters, mainly voltage level and its symmetry. The inverters operation in electric vehicle charging stations (EVCSs) generates harmonics, which also leads to deterioration of the voltage quality. In the case of simultaneous charging of a large number of EVs from a poorly designed distribution grid, significant losses inside conductors occur, and the service life of the distribution grid is shortened. In the paper, the authors deal with the modelling of EVCSs by using an alternative simulation tool when charging them as a power load, which consumes predefined active power with desired level and duration at supply voltage changes in the grid. Such defined load differs from a general load in its behaviour. The authors’ created load model is based on the real measured data. The behaviour of the created power load model is verified in the paper on a small distribution grid, where individual power consumers correspond to the standardized daily load diagrams of households and services. The goal of the paper is to verify the proposed power load model. The load model is used for solving active power losses in conductors of the electrical distribution lines, and mainly the levels of supplied voltage.
