Title: A control strategy for photovoltaic system connected to grid
Biography: Khalida Zazi
Photovoltaic energy has experienced great development. Research around the world covers this wide-ranging field, and tries to improve the performance of photovoltaic systems through manufacturing processes and the exploitation of new photovoltaic cell concepts and development of novel MPTT control strategies to ensure a good transfer of energy and eliminate the harmonics distortion of current and voltage in a photovoltaic system connected to grid a new ADRC technical control is implemented to achieve maximum power point (MPP).The performances of grid connected photovoltaic power system using DC-AC power inverters is studied using an active disturbance rejection control ADRC strategy developed to extract the maximum power of the solar energy, to maintain constant the DC-bus voltage, and to inject a suitable current into the grid with power factor near unity. It is susceptible to power grid disturbance, sudden environment changes and parameters uncertainties.
