9 Research activities Marco Liserre

10 A. Multilevel converters: modulation and control
PI-based and passivity-based control of H-Bridges multilevel converters Back-to-back drives for traction systems Multilevel modulations and their implementation on FPGA systems Marco Liserre

11 B. Three-phase active rectifiers
LCL-filter design and passive/active damping of control loops Back-to-back drive with reduced energy storage Fuzzy-sensorless control for low-cost microcontrollers Marco Liserre

12 C. Power quality assessment criteria and active compensation systems
New power quality assessment criteria for non- linear loads Predictive, fuzzy and fuzzy-predictive controls of active filters Optimal tuning of active power filters via genetic algorithms and Nelder-Mead method Marco Liserre

13 D. Power converters for distributed power generation systems
PV and WT simulators PV converters Anti-islanding methods Control of a PMSG-based wind turbine without speed sensors Power quality improvements through DPGS Projects involving companies: a regional research project in the field of PV-systems: reactive power control has been tested (Rienergia company involved) a project with Jonica Impianti company to build the converter for a small WT Marco Liserre

14 Photovoltaic system emulator
SOLAR PANEL SIMULATOR SUN SIMULATOR simulator of temperature and irradiation Photovoltaic system emulator Aims: to create a realistic test bench for photovoltaic inverter To predict MPPT and other control algorithms behavior when the inverter is installed Items: 2 software: Sun simulator and Solar panel simulator Hardware: Dc source simulator of photovoltaic panel dc source MPPT inverter grid System under test Marco Liserre

18 Wind emulator only changing the parameters of the controllers
It controls a motor to act as the blades and gearbox of a wind turbine. The motor is directly coupled to the generator and power converter under test only changing the parameters of the controllers Marco Liserre

19 PV converters: step-up inverter
The system consists of three dc/dc boost converters with a common point and operating as a three-phase inverter with intrinsic step-up capability. The converter obtained can invert, amplify and, where possible, regenerate bidirectional power sources such as fuel-cells, small gas turbines and photovoltaic arrays. There are two main advantages to the system: the use of only six IGBTs and small passive elements, and the fact that it does not need reverse voltage blocking capability. Marco Liserre

20 PV converters: transformerless converter
The research has been focused on transformerless photovoltaic inverter topologies for three-phase grid connection with the main focus on the safety issues that result from the lack of galvanic isolation. A common-mode model, valid at frequencies lower than 50kHz, is adopted to study the leakage current paths. Research developed in cooperation with a PhD student working for “Electrical Energy Conversion and Condition”, European Project “MARIE CURIE: Early Stage Training Fellowships (EST)”, University of Nottingham. Local coordinator Prof. A. Dell’Aquila (€ ). Marco Liserre

21 Anti-islanding algorithms
The research has been started with a deep simulation and experimental comparison of the passive and active methods used for islanding detection. Then the research has been carried out on Kalman-filter-based and wavelet-based methods for islanding detection The research developed in cooperation with a visiting reasercher from Spain has originated the following project “Algoritmos para la detección de la condición de isla eléctrica en inversores aplicados a sistemas de generación fotovoltaica distribuida de acuerdo con la normativa europea” Coordinatore Víctor M. Moreno Sáiz, Università della Cantabria ( €) Marco Liserre

22 Control of a PMSG-based wind turbine without speed sensors
The research has been started with a deep simulation comparison of the diode-bridge based and back-to-back power converters. Then it has been focused on the speed-sensorless control of generator inverter Marco Liserre

23 Power quality improvements through DPGS
Also low power PV systems can be designed to improve the power quality. They can provide grid voltage support and compensation of harmonic distortion at the point of common coupling (PCC) Marco Liserre
