Performance Evaluation of Enhanced Active Power Control Maximum Power Point Tracking Algorithm for Photovoltaic Grid Tied Systems

Abstract

Day-to-day power intake to the grid from all electricity generating sources was rising, as the fact that due to the modernization of all industrial and household applications, which are now primarily powered by electricity. As a result, non- conventional energy sources are used to feed the grid and meet the load demand. Out of the existing non-conventional sources of energy, solar Photovoltaic systems that are tied to the electrical grid will be a prominent form of energy in power system networks to meet the load demand for the approaching years. Every researcher in the field of solar systems must begin with the design of the solar photovoltaic module (SPVM), and this thesis gives a full mathematical design model for the SPVM as well as the solar photovoltaic array (SPVA). The SPVM is designed and developed to extract its electrical properties, which were influenced by solar irradiance (G) and temperature (T). This thesis investigates the simulation and mathematical design of SPVA by taking the parasitic effects of shunt resistance (Rsh) and series resistance (Rs) to match the simulation and hardware outcomes. In this work, an inverse slope technique is used to obtain the precise values of shunt and series resistance. Parasitic effects are derived from the solar photovoltaic (SPV) panel manufacturer s datasheet using the inverse slope approach. These design guidelines may be used to replicate the behavior of a wide range of large-scale SPVAs in the real-world scenario of any system. The modelling and experimental verification of SPVA are done by considering the IB Solar-36 polycrystalline panels with variable T and G values. newlineIn this thesis, a comparative analysis of maximum power point tracking algorithms has been done extensively which were widely used in literature with the proposed enhanced active power control (EAPC) algorithm. The SPV modules in the real-world scenario facing issues with varying environs as well as partial shading conditions (PSC) which directly affect the cell voltage in the modules
