Modeling of PV Array and Performance Enhancement by MPPT Algorithm

摘要: This paper proposes modeling and simulation of photovoltaic model. Taking in to account the temperature sun‟s irradiance, PV array is modeled its voltage current characteristics power are simulated. enables dynamics system be easily simulated optimized. It noticed that output a influenced by environmental factors conversion efficiency low. Therefore maximum tracking (MPPT) technique needed track peak maximize produced energy. The point –voltage graph identified an algorithm called perturbation & observation (P&O) method or Hill climbing. will identify suitable duty ratio which DC/DC converter should operated output. results confirm photo voltaic with proposed MPPT controller can operate for whole range assumed solar data (irradiance temperature).
