In this paper, a new software tool is presented for the simulation of electrical networks under steady-state conditions. Its distinct advantage is the robust integration of distributed generation droop controls, while offering the ability to simulate extended networks fast and reliably. The proposed simulation tool is based on the combination of two well-known software products, namely MATLAB and...
Penetration of distributed renewable energy sources in low-voltage (LV) networks is increasing steadily. This trend helps the vision of sustainability, but it is hindered by various economic and technical constraints. Some of the existing solutions put some customers in a disadvantageous position, which is often overlooked while developing technical solutions. In this paper, the most common solutions...
This paper investigates the differences that occur in the propagation characteristics of underground cables, calculated using two individual earth return approaches. The first approach assumes that the influence of the imperfect earth is taken into account only on the cable impedances, using the well known Pollaczek-Sunde earth return impedance formula, while in the second model new formulas for the...
