Floating PV Distributed Generation System Proposal and Optimal LCL Filter Design for Akköprü Dam, Muğla, Turkey

Abstract

The study investigates the burgeoning potential of floating photovoltaic (FPV) panels and proposes their installation in Akköprü Dam, Muğla, Turkey. Also, different kinds of power electronics-based converters and inverters are used in the grid integration of FPV. These electrical gadgets cause harmonics in voltage and current waveforms to be introduced into the grid. Therefore, a 2 MW FPV system is designed to be combined and connected to the 120 kV common grid by a 25 kV distribution feeder. This research examines optimal passive filter designs and harmonic analysis for FPV power systems. Also, utilising real-world meteorological data that is taken from Dalaman, Muğla, Turkey, such as solar irradiation, as an input parameter of the FPV. After that, to study harmonic analysis and optimal filter design, a mathematical strategy is proposed. Moreover, the arithmetic mean (AM) of real data is considered the input value of FPV. Also, to discover the best filter solution, the Antlion Optimisation (AOA) algorithm is used. According to IEEE 519 standards, the optimisation method seeks to minimise both the voltage levels in p.u. and the total harmonic distortion (THD) of current and voltage values. Moreover, the FPV model is simulated with optimal LCL filters by using daily data (DD) solar irradiation values. Finally, the performance analysis based on the results of AM data and DD is studied. Lastly, the results are comparatively discussed.
