“…These levels represent normal variations in the behavior of the solar panels in relation to irradiance on the solar cells and their temperature (the use of Maximum Power Point Tracking is supposed). In recent works, we have reflected these variations (both measured and calculated by using implicit and explicit models) [59,60,84].…”

“…The aim of this work is to describe the preliminary results obtained from a research collaboration framework established by researchers from ETSI Civil and the IDR/UPM Institute to analyze the effect of renewable energy sources (as DG) on the protection devices of a power grid. The aforementioned framework is based on the work already carried out on protection in power grids with distributed generation [50], and the work carried out in analytical modeling on solar panels and batteries [51][52][53][54][55][56][57][58][59][60]. In the present work, photovoltaic energy was selected as the example of DG.…”

The increase in the installation of renewable energy sources in electrical systems has changed the power distribution networks, and a new scenario regarding protection devices has arisen. Distributed generation (DG) might produce artificial delays regarding the performance of protection devices when acting as a result of short-circuits. In this study, the preliminary research results carried out to analyze the effect of renewable energy sources (photovoltaic, wind generation, etc.) on the protection devices of a power grid are described. In order to study this problem in a well-defined scenario, a quite simple distribution network (similar to the ones present in rural areas) was selected. The distribution network was divided into three protection zones so that each of them had DG. In the Institute of Electrical and Electronic Engineers (IEEE) system 13 bus test feeder, the short-circuits with different levels of penetration were performed from 1 MVA to 3 MVA (that represent 25%, 50%, and 75% of the total load in the network). In the simulations carried out, it was observed that the installation of DG in this distribution network produced significant changes in the short-circuit currents, and the inadequate performance of the protection devices and the delay in their operating times (with differences of up to 180% in relation to the case without DG). The latter, that is, the impacts of photovoltaic DG on the reactions of protection devices in a radial distribution network, is the most relevant outcome of this work. These are the first results obtained from a research collaboration framework established by staff from ETSI Civil and the IDR/UPM Institute, to analyze the effect of renewable energy sources (as DG) on the protection devices of a radial distribution network.

“…In this project, based on the expertise of the IDR/UPM Institute in this field [15][16][17][18][19][20][21][22][23][24], a numerical simulator of the EPS of TASEC-Lab has been modeled to predict its performance (i.e., battery voltage and power dissipation) during operation. For this purpose, several laboratory tests have been conducted and a set of experimental data has been used to develop analytical models of the main electrical parts: a Li-ion battery and two DC-DC converters.…”

“…Different efficiency models have been implemented to select the one that best reproduces the behaviour of the DC-DC converters. In the first model, here called "Exponential" and developed at the IDR/UPM Institute [31], the efficiency of the converter is a function of the output current (see Eq. ( 12)) and is independent of the input voltage.…”

“…The UPMSat-2 represents an exceptional platform for studying the performance of solar panels as Sun sensors. This mission has represented extensive work on the simulation, calibration, and characterization of several components and subsystems of the satellite, such as solar panels and the power subsystem [27,52], or the attitude determination and control subsystem • SSBV magnetometers.…”
