Title: Grid-Connected Converters: Key Elements in Future Power Grids
Abstract: The capacity of installed converter-based distributed generators (DGs) and renewable energy sources (RESs) over the world is rapidly growing; and this increases the significance of grid-connected converters (GCCs) that interface the primary power sources to the grid. It is well known that the quality of control and functions of these power converters in different operation modes significantly affects the grid dynamic performance.
Moreover, the increasing penetration of converter-interfaced RESs and the control flexibility of GCCs motivate the use of these converters to develop additional ancillary services to control undesired system dynamics in the power grids. Moreover, appropriate control of GCCs has the potential to offset the intermittent nature of distributed energy resources and provide control support to the host utility during abnormal conditions. To this end, in the present speech, some new trends in GCCs modeling, control, and new functionalities in the visualization of virtual dynamics will be discussed.

Title: Cyber Security Breaches in Renewable Energy Power Plants and Conventional Power Plants
Conventional power plants are located only at a single or a few locations making them easier to security controlled physically. However, when renewable energy devices come into the picture, the feeding points are very widely distributed, for example wind turbines or solar power plants. Each wind turbine or a solar installation is an entry point to the national grid making the infrastructure vulnerable.
Access authentication, patch testing, implementation, and user education are vital parts of security. The present work looks at the modes and cost implications of security breaches in power plants, especially renewable energy powerplants. There is a significant shift in the security landscape when renewable energy sources are connected to the grid, making everything all more vulnerable and making the infrastructure cost and the cost of disruption significantly higher.

Title: Advances in Aerodynamics and Structure Dynamics of Offshore Wind Turbine with Lower Reynolds number
High aerodynamic performance and lightweight design are of fundamental importance in offshore wind turbine with lower Reynolds number, and are the well-established subjects of scientific investigation that attracts great interest of the mechanics community. Indeed, there are a very rich variety of singular or nonlinear phenomena in aerodynamics with lower Reynolds number, for example, flow separation, stall, breaking of separation bubble etc. Roughly speaking, such kind of singular phenomena can be considered as extreme events, and they may be natural or anthropogenic as the parameters are beyond the critical values. There exist some physical meanings in them, and scientists try to understand what lead to extreme events, how they develop, and when and where they could occur, since there exist relationships between singularities and aerodynamic performance.
For example, the breaking of separation bubble is the main route to vortex shedding, which is a complex unsteady flow. More, it has an important influence on the aerodynamic performance near stall. Recently, experiments show that some kind separation bubbles and their breakings, which are induced by some unsteady perturbations or excitations, can lead to the improvement of the aerodynamic performance in a sense. For such kind of singular phenomena, the dynamic behaviors, such as mass and momentum transfer, play important role in their formations.
For complex unsteady flow, the traditional Eulerian description is no longer available to describe such dynamics, which is related to mass and momentum transfers. To this end, Lagrangian Coherent Structures (LCSs) are used to describe the Lagrangian dynamics, and the Lagrangian patterns, which are inherent following their definitions, is captured. More, LCS is used to study the modes in such complex flow, in order to find the fundamental modes which dominant the flow pattern and aerodynamic performance. Also, the mode jumping or mode transition and internal resonance between modes can be studied further.
In the presentation, Lagrangian Coherent Structures are introduced firstly, and then some typical singular behaviors in the flow around airfoil are studied using LCSs. In particular, the bifurcations or instabilities of flow structure or LCSs patterns are analyzed numerically, as well the relationships between singularities and aerodynamic performance.
Similarly, there exist some nonlinear phenomena in aeroelasticity or fluid-structure interaction, such as nonlinear energy sink (NES) and targeted energy transfer (TET), and lightweight design could be carried out as gaining the key understanding of the nonlinear phenomena. In the presentation, NES and TET are explained in detail, and some examples are given.
As a conclusion, the results show that LCSs presented is powerful for the analysis of the complicated flows around airfoil, and some nonlinear phenomena can be captured and analyzed by the method. Further, the aerodynamic performance can be improved feasibly by controlling or modifying the LCSs or fundamental modes. Moreover, lightweight design of offshore wind turbine can be reached as NES and TET are introduced.
