Study the Effect of Integrating the Solar Energy Source on Stability of Electrical Distribution System

The increment in industrial demand for electrical power come to search for alternative clean and cheap energy sources. One of these choices is the renewable energy sources. So, there are some energy sources now can connect to the main electrical distribution networks which may led to influence the stability and performance of the system. In this paper, number of technical parameters related to electrical power quality have been tested in order to determine the influence of integrating the solar source on electrical distribution network. The investigation has been carried out by calculating the losses in active power, reactive power and the voltage value of electrical distribution network after connecting the solar source though the main distribution grid. Simulation model was performed with MATLAB Simulink and the final calculation results were compared with the electrical standard (9-IEEE bus network). The obtained results indicate that the integration of solar source with the load distribution grid can cause some losses in active and reactive power.
