Title: Exploring the Future of Tidal Stream Turbine Drivetrains: A Journey into Technology Options
Abstract: Tidal stream energy is one of the promising solutions to lower CO2 emissions. It is sustainable and predictable. In fact, tidal current oscillations are highly predictable, unlike other types of energy. Tidal stream energy is usually harnessed using horizontal axis tidal turbines, which are analogous to wind turbines. However, the maximum power extracted from a tidal turbine is 61% higher than a wind turbine of the same input power because of the higher density of water over air. Tidal stream turbines are submerged systems so they have to withstand high loading and harsh submerged conditions. Furthermore, many challenges have to be overcome to improve their reliability, availability, and decrease maintenance costs. In particular, the turbine drivetrain and generator option choices affect the availability as well as the cost of energy. In this challenging context, this keynote will address the critical issue of tidal stream turbine drivetrain options, while proposing trends and discussing potential and promising topology options.

Title: Possible Applications of FACTS Devices in Iran Power System
Abstract:
The steady state operating point of a power system can be determined by a load flow calculation. This means that generation units' conditions and loads connected to the network, dictate the power flow amount of transmission lines and the voltage of power system buses. To change the operating point of the power system, we need controllers, which can be used in generation units, transmission lines and distribution networks. Flexible AC Transmission System (FACTS) devices are static power-electronic devices installed in AC transmission system to realize the power flow control. Considering their structure, which is based on power electronics devices, they can also influence the dynamic behavior of the system. Therefore, it can be said that they can enhance power transfer capability, improve stability, and increase controllability of the power system.
In this talk, first, the structure of these power-electronic-based controllers, known as FACTS devises, will be introduced and their effects on power system transmission parameters will be offered. Then, the applications of FACTS devices will be presented and considering the current challenges of Iranian power system, their possible applications, especially enhancing voltage and reactive power margins, will be discussed.
