Power Electronics Technology – Quo Vadis
The world is becoming more and more electrified combined with that the consumption is steadily increasing – at the same time there is a large transition of power generation from fossil fuel to renewable energy based which all together challenges the modern power system but also gives many opportunities. We see also now big steps being taken to electrify the transportation – both better environment as well as higher efficiency are driving factors. One of the most important technologies to move this forward is the power electronics technology which has been emerging for decades and still challenges are seen in the technology and the applications it is used. This presentation will be a little forward looking (Quo Vadis) in some exciting research areas in order further to improve the technology and the systems it is used in. Following main topics will be discussed
- The evolution of power devices
- Renewable Generation
- Reliability in power electronics
- Power Electronic based Power System stability
At last some discussions about other hot topics will be given.

Smart Wearables for Comprehensively Monitoring Hand Signs in Human-Machine Interaction
The demand for wearable systems for human-human or human-machine interactions is nowadays continuously increasing. Several sensors can be adopted including biocompatible flexible sensors based on polymer carbon nanotubes composites (PCN), bio-impedance spectroscopy, surface electrical impedance myography (sEIM) and electrical impedance tomography (EIT), Electromyography (EMG) and inertial measurement units (IMU). Multi-modal systems, incorporating a variety of sensors and techniques, enhance the precision and dependability of continuously monitoring human activity, behavior, latency, and intentions. These systems not only enable cognitive feedback but also ensure increased accuracy and reliability. Wearable embodied solutions offer the ability to build body-attached sensor networks that meet compactness, accuracy and reliability requirements an enable body activity monitoring and communication even in complex interaction scenarios.

Renewable Energy Systems: Control and Monitoring Issues & Technology Trends and Challenges
Renewable energy technologies play an important role in sustainable development by reducing gas emissions, improving energy security and providing access to energy to remote areas. But, the intermittency of sunshine and wind cannot provide an on-demand power source 24 hours a day. Furthermore, solar energy and wind are practically unpredictable. So, there is inconstancy and uncertainty in generation and inconstancy in loads. Moreover, renewable energy systems reliability is essential and maintaining a continuous power flow is fundamental. Monitoring renewable energy systems balance may increase the reliability of these power supply systems. Elsewhere, several issues of grid connected renewable energy systems (voltage fluctuations, voltage imbalance, voltage rise and dips and reverse power flow, power factor correction, power quality) have to be overcome by implementing special procedure in the RES management strategy (LVRT, HVRT, active filtering, …). Furthermore, to deal with the intermittency of these sources (with a power generation depending on natural resources that are uncontrollable) one may develop energy storage systems with huge storage capability (which is not the case of the current pumped hydroelectric storage, battery storage system, green hydrogen production …). Elsewhere, the most challenge of RES is the transition to a less carbon-intensive and a more sustainable energy system. Moreover, the cost of upfront financing, grid connection requirements and lack of grid capacity become more and more constraining and restrictive; and needs to be alleviated and lightened.
In this session, the issues of monitoring and control of renewable energy systems and the techniques that can be used to provide solutions to reduce the intermittency constraint effect, enhance the power quality and to contribute to ancillary services of power systems (AGC, AVR…), will be addressed. Besides, current technology trends and challenges of RES will be discussed to show how to improve the wide spreading of renewable energy technologies by transporting electricity from areas where solar and wind energy are abundant to other areas, storage of energy from intermittent sources such as wind and solar, and performing a more flexible and efficient electrical smart grid that can promote the use of renewable electricity.
