PV system characterization and optimization

Technology in the solar power industry has been drastically improved the last years, turning solar into a major renewable energy source with the potential to meet many of the challenges facing the world.

Due to many advantages of solar power energy such as environmental sustainability, renewable, accessibility, low maintenance costs, diverse applications and economic saving, solar photovoltaic (PV) panels indeed have a highly promising future both economically and for environmental sustainability.

At the Centre for Industrial Electronics and SDU Electrical Engineering, we are doing research and development within PV system characterization and optimization. The work encompasses new ways to improve both performance, reliability and device efficiency by introducing new ideas to minimize an intermittency effect. This includes research and development activities on:

  • PV-plant topographical effects
    Inclusion of topographical site-information into the yield estimation models for PV-plants.
  • Photovoltaic inverter topology for large PV-plants
    Optimization of string- and central inverter topology at large PV utility plant with varying topography.
  • Photovoltaic modules characterization
    Long term characterization and comparison of emerging module types under real-life operating conditions.
  • Decentral battery storage
    Use of batteries as intermittent energy storage to optimize annual energy use.
