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.

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

8. PV CURVE FROM SIMULINK
AT VARIOUS IRRADIANCE

9. MAXIMUM POWER POINT
TRACKING

13. 3 PHASE SPWM

14. POWER FLOW

15. D-Q REPRESENTATION
•A simplified way of representing a set of 3
sinusoidally-varying phase currents and voltages using
only 2 values
•Uses only the XY coordinates of a simple vector (d-q)
•Greatly simplifies the control system for power
system inverters

17. PHASE DETECTOR
