Simulation and Validation of SPV Micro Grid comprising Five one Eight point two KWp Distributed Solar Power Plants at Dayalbagh Educational Institute

Abstract

newlineThe main challenge for any solar photovoltaic power plant is to come up with an economic, efficient and reliable system in the presence of generation sources, dynamic loading conditions dependent on the vagaries of weather and non-reliable power utilization. newlineThe above mentioned challenge can be over come using integrated operation, monitoring, communication, control and fault diagnosis of all the solar electric power plants through a central control system. This would lead to the philosophy of smart micro grid. The main part of the smart micro grid is a decision support system to assist the operator for achieving optimal efficiency, reliability and economy in system operation. This makes a good simulation model of the micro grid, very essential. newlineLiterature survey reveals that even with a vast literature available in the area of simulation of PV systems, work on integrated modelling and simulation of entire PV systems is still lacking. Most of the research work is based on individual component modelling rather than an integrated PV system model. Hence this research aims to integrate individual component models and present the overall PV system model of an actual solar power system. newlineThe main focus of the proposed thesis is modelling and simulation of the micro grid comprising of seven distributed SPV power plants interconnected through a distributed network at Dayalbagh Educational Institute. The objectives proposed and achieved in this thesis are given below newlineand#61692; Comprehensive Modelling of PV Power Plant (chapter 2) newlineand#61692; Modelling, Simulation and Validation of PV Arrays (chapter 3) newlineand#61692; Modelling and Simulation of 3-Phase Inverters (chapter 4) newlineand#61692; Modelling and Simulation of Battery Banks (chapter 5) newlineand#61692; Modelling and Simulation of MPPT Charge Controllers (chapter 6) newlineand#61692; Modelling and Simulation of Integrated Grid Connected SPV Plants at DEI (chapter 7) newlineThe results of each of the above simulations are presented in the corresponding chapter. newline
