October, 16th -17th, 2019  

It is time to share our experience and results. Due to the fact that the project will end up in 2019, all interested people are registered to our MIGRATE Roadshow. The project provides five different workshops in Europe in which the results of the last four years will be shared. L2EP was involved in the WP3 that deals with the massive integration of generation based on power electronic. In this context, L2EP organizes the WP3 workshop. The first day is devoted  to presentations of accomplished  work. Demonstration, tutorials and expert roundtable panel  are scheduled on the second day. The full program of the workshop is detailed below:

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
    • power measurements at 10%,20%,30%,50% and 100% of the rated Power
    • Efficiency and EU efficiency computations
    • Minimum and maximum AC voltage protection testing
    • Minimum and maximum frequency protection testing

PLUTON

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. 
  • Lasting:           since February 2017

IRIS

Description:

The Integration of Real time simulation on FPGA components or IRIS project is the joint effort of EPM laboratory and SPHEREA Test and Service company aimed to develop a new real time simulation system for power electronics and electrical machines based on a custom fast computational hardware implemented in Field Programmable Gate Arrays.

The product testing and maintenance is an important part of its life cycle in the industries with high security and quality demands such as aerospace, transportation or energy production. It allows reducing the risks of accidents, prevents financial losses due to systems failures in energy production and to increase safety. The testing can be very costly for big and complex systems such as an airplane or an electrical station but, although necessary, it can be replaced by a real time simulation at the first stage of the controllers and subsystems verification. In some cases, the testing on the real hardware can be even impossible if a response to faulty conditions is to be checked. The hardware in the loop simulation allows carrying out integral tests of the control systems and independent subsystems without connecting to the actual real-world equipment to greatly reduce the costs and damage risks.

The conventional HIL simulation systems doesn’t allow real time simulation of systems with very fats dynamics such as electrical power systems and machines. The IRIS project is centered around solving the dynamics equation of electrical systems and its acceleration with FPGA/System on Chip. Currently it includes the solvers for generic linear electrical systems based and power electronics the augmented nodal method, and synchronous electrical machines based on state space modeling, but additional type of solvers are planned to be developed. For both these methods a lot of computational power is required if fast real time dynamics simulation is to be achieved. Form the other point of view, the real-time simulation requirements impose the constraints on the loopback response latency. 

To respect these constraints the IRIS project uses hardware computation acceleration and input outputs control base on FPGAs – electronic components allowing to build reconfigurable digital logic circuits. Compared to conventional microprocessors they provide much larger flexibility and optimization of computation pipelines and compared to such devices as GPU they allow hard real time determinism insuring that a proper signal will be sent in the proper place and at the correct time which is very important for the communication with tested equipment and controllers. 

The IRIS simulation system has a modular architecture with asynchronous simulation modules designed for the specific electrical system simulation. The simulation modules are controlled and configured from the system on chip with an ARM core which is also used for host PC communication. This allows online configuration and reconfiguration on the fly to treat non-linearities and slow dynamics that can also be simulated on software part. 

The solvers developed in the IRIS project can be used for simulation of electrical power systems for the first stage testing and verification. It can be applied for testing and verification of power production, onboard power grids, electric propulsion and mechatronics in aerospace, automotive, railroad and power production industries.

MTDC Experimental Grid

Identification:  “Multi-Terminal DC grid mock-up for off-shore energy production”

Description: 

  • Main Topic : control of MTDC grids
  • Aims: DC voltage and AC frequency control

The growth of offshore wind farms and their geographical dispersion will perhaps lead to a multi-terminal DC (MTDC) configuration. The control strategies of DC system should consider both DC voltage constraints and frequency support of interconnected AC grids.

In the different stages of development for technological applications, the low scale demonstrator is a very important validation phase after the theoretical simulation analysis and prior to first prototypes or industrial installations. In terms of development of MTDC grids, it could still last for many years before getting the first on-site high voltage demonstrator, mainly due to the huge costs involved in such projects and to their impact on the operation of exiting grids. Therefore, the mock-up developed in TWENTIES demo3 provides an interesting intermediate and flexible step between simulations and on site demonstrator by mixing reduced power DC links and real-time simulation to develop an actual low power MTDC grid. This DC grid can be interconnected to a virtual AC power system.
