Power electronic converters on transmission system from fundamental considerations to practical applications
Registration is closed
11 – 13 July 2022
Objective
The number of power electronic converters is increasing quickly in all the different parts of the grid. The electrical power system is moving from the “electromechanical world” to the “power electronic world”. The aim of this course is to contribute to build a bridge between the two worlds by using simplified models of power electronic converters and by integrating the key parameters and needs of the power system in the control design of the converters. The control algorithms will be built step by step starting from fundamental considerations about physics and introducing progressively the different functionalities required for a converter connected to the grid. The classical grid following control will be addressed and its limitation highlighted but the focus will mainly be done on the grid forming control. From these fundamental analyses, some practical applications will be derived such as wind turbine control, storage or HVDC systems. The participants will progressively build their own control by using predefined models of converters.
Target Audience
The target audience is Phd students working in power electronic applied to power system and people from the industry working in the same topic.
The models of power electronic converters will be simple enough to be understood by any person with some basic knowledge about electrical engineering and control.
Teaching method
The program of the course is a mix between some theoretical contents closely connected with some practical simulations on Matlab/Simulink and Simpower system. All the simulation files can be loaded on its personal computer or run online by using Matlab Online (in this case, computers will be available). These simulation models will be freely available and may be used freely for other applications. Several speakers from industry will also propose some conferences in order to bring their practical experience. All the different model parameters will be using some realistic parameters drawn from practical data.

Aims:
To propose and develop novel control and management rules for a transmission grid to which 100 % converter-based devices are connected while keeping the costs under control;
To check the viability of such new control and management rules within transmission grids to which some synchronous machines are connected;
To infer a set of requirement guidelines for converter-based generating units (grid codes), as far as possible set at the connection point and technology-agnostic, which ease the implementation of the above control and management rules.

Context: Micro-inverter is the youngest solar inverter technology. The main argument in favor of the use of micro-inverters is that their connection is easy and allows to have “plug & play” PV modules. Also, the growth of this market is based on the capacity of low skilled workers to realize PV installations. Moreover, the number of micro-inverter manufacturers is rising since the last three years. Thus, it is difficult to compare the product among themselves.
Main results:
Develop a PV micro-inverter test bench
Results comparison to manufacturer data

Identification: “Power amplifier for ultra-fastAC/AC conversion”
Context:
To insure the security and reliability a complex and wide coverage tests must be carried out during the whole life-cycle of the products in such industries as power production, aviation, electrical vehicles and railways. The power hardware in the loop or HIL simulation is more and more used to reduce testing costs and protect the real hardware from faulty controllers and in faulty condition tests. The electrical power systems such as drives and converters have a very fast dynamic and cannot be emulated using classical HIL equipment. The IRIS and PLUTON projects aims to develop new power hardware in the loop by exploiting new power converter topologies coupled with the Field Programmable Gate Arrays (FPGA) computing capability for drastically decreasing the simulation time steps allowing the real time simulation of the electrical power systems.
Aims:
Development of ultra-fast AC/AC conversion power amplifier for Powerhardware in the loop applications.
Coupling this power amplifier and the IRIS solver.
