Simulations

Project Simulations 

  • This stage is where the initial assembly of project & simulation begins

  • This stage has taken the most amount of time since we first needed to run various simulations before working with our actual components (we did not want to damage any equipment)

  • The simulation of our PV/Wind hybrid system were done using MATLAB Simulink

Solar PV System

The model used in this project is based on the single-diode model and extracting some of the parameters from the manufacturer data sheet. The following figures show an equivalent circuit of a Photovoltaic cell and a Simulink model.

Wind Turbine System

A wind turbine converts the kinetic energy of the wind into mechanical energy transmitted by shaft. In our project, the wind generator power output is estimated through interpolation of the values of the data provided by the manufacturers. As the power curves are quite smooth, they can be approximated using a cubic spline interpolation.

Battery Modelling

At any hour the state of battery is related to the previous state of charge and to the energy production and consumption situation of the system during the time from t-1 to t. During the charging process, when the total output of PV and wind generators is greater than the load demand.

Completed System

In our system, we are combining together two electrical power generators and an electrical power storage component to meet the electrical power demand of a given community. In this project, Solar PV and WECS are combined to get hybrid system which is delivering DC power to DC load combinable.
