This document discusses the analysis of grid-connected solar photovoltaic (PV) systems, highlighting the conversion of DC power to AC power to meet utility grid requirements. The project's goal is to optimize power utilization from the grid and supply surplus energy generated from solar systems back to the grid. Additionally, it covers modeling aspects using MATLAB/Simulink for PV modules and inverter control strategies.
Mid term report on analysis of grid connected PV system
- 1. ANALYSIS ON GRID CONNEC TED PV SYSTEM PresentedBy: Ishwor singh(BEL/070/219) Khaga Raj subedi (BEL/070/221) Kishor ghimire(BEL/070/222) Ramesh adhikari(BEL/070/233) Project Supervisor:S K
- 2. INTRODUCTION • Solar PV systems are generally classified into Grid- connected and Stand-alone systems. • In grid-connected PV systems Power conditioning unit (PCU) converts the DC power produced by the PV array into AC power as per the voltage and power quality requirements of the utility grid. Fig: block diagram of grid-connected solar PV system
- 3. OBJECTIVE • The main objective of the project is to utilize the deficient power required for solar energy system through grid and to fed surplus power of the solar energy system to the grid
- 4. OUR PROJECT INVOLVE Modelling of Grid Modelling of PWM & PLL (Inverter control) Modelling of inverter Modelling of PV module
- 5. PV MODULE MODELLING Modelling of PV Module is designed in Matlab/Simulink based on these Equation:
- 7. IV CURVE FROM SIMULINK AT VARIOUS IRRADIANCE
