| Popis: | At present, the worldwide concern about climate changes on or planet is indisputable. One of the aspects that influences environmental problems is the generation of energy through conventional methods. Due to this, the governments all over the world, and particularly Ecuador, have opted for the implementation of renewable energy for the electricity supply. In the Ecuadorian case, for example, the government established a program called “towards a new energy matrix” and also regulations to promote the use of renewable energy sources for energy purposes. Taking into account this considerations, and the possible technical challenges that Distributed Generation (DG) could create, it is necessary to study the behavior of networks after the introduction of (DG). In this thesis, the standard IEEE 13 buses distribution feeder and a real distribution feeder were chosen in order to carry out two solutions mode which are snapshot power flow and Quasi- Static Time Series (QSTS) power flow. These networks were modeled and simulated using OpenDSS, a software used in scientific literature to analyze the impact of DG in electrical power distribution systems. For IEEE 13 buses feeder, five different scenarios were defined to evaluate technical features such as losses, voltages profiles and reversed power flow; only PV generation was considered for this network while for CENTROSUR network it was considered three case of study with five scenarios each one. The cases of study for CENTROSUR were: i) only PV, ii) PVs integrated with BESS and iii) PVs integrated with BESS and induction cookers. In order to carry out simulations for CENTROSUR network, the transformer demand profile, the storage system profile, the PV profiles and the load consumption profiles of 10 minutes of resolution was used. |
