Description
In recent years, low-voltage networks have become particularly attractive. More and more small-capacity solar power plants are joining them. The motivation that owners receive is a combination of the affordable price of the systems, a simplified procedure for obtaining a design and construction permit. The creation of energy independence is also not in last place.
Despite their local impact, all of them taken together have a significant impact on the operating parameters of the electrical networks. Power losses and, respectively, electrical energy are among the main operating parameters that will be affected.
The most commonly used methods for estimating electrical energy losses in low-voltage distribution networks are examined, depending on the information provided. It is proposed to take into account the seasonality coefficient, which would increase the accuracy of the models.
Depending on the operating conditions, the network configuration and its declared voltage, different methods are applied to calculate the network operating parameters, such as voltage levels in the nodes, power losses and electrical energy.
