This Book proposes a New Harmony Search (HS) algorithm for improving the Optimization and performance of Maximum Power Point Tracking in PV System. The Harmony Search (HS) algorithm technique has been applied for multi junction solar cell system. The solar panels are made up of different materials and give constant output from Boost converter. The main aim of Harmony Search (HS) algorithm is to find out duty cycle to the Boost converter to maintain constant output voltage irrespective of power produced by solar panels. This proposed harmony search algorithm (HSA) is also used to minimizing...
