| Popis: | Electrical systems with high penetration of renewable energies are increasingly common. Among these sources, wind energy is the one that has most propagated with the technology in great development and the fact that much of the world population density is located in the coastal where there is strong incidence of winds, favoring the installation of large parks that will not need of long transmission lines for delivery this energy. Power through tidal current streams is a promising source as it presents as one of the advantages the high predictability of energy resources. Power systems analysis tools need to include these technologies as they are a worldwide trend. This paper aims to present a probabilistic modeling to include these sources in the optimal power flow problem. For this, wind farms, tidal currents and hybrids ones were modeled. They were included in the network as a form of power injection to analyze the operational system costs. The methodology was applied in the WSCC test system and had shown that the costs are significantly reduced, and that complementarity among the sources is an important factor for the constancy of the output power of the source. |
