Abstract
As renewable resources become more commonly connected to assist the generation of electricity, energy storing systems increasingly come to life. The need for energy storing systems became very crucial with the integration of renewable resources for power quality improvement, back up generation and economics. Due to the huge integration of renewable resources, the necessity of using the power electronics in transmission and generation systems became progressively important.
The Battery Energy Storage Systems (BESS) is one of the devices that have enjoyed much interest lately. It poses great challenges to whom would design and implement the following generation of smart grids to help integrating both solar power and wind power. To make these resources more economical and efficient, the location and the rating of the batteries is very crucial with respect to the performance.
This study introduces an investigation on a micro grid before and after integrating a BESS on a network with photovoltaic (PV) cells and a network with a wind farm (WF), illustrating the effect on power quality on both frequency and voltage wave forms. Also, the study will examine the BESS effect on a hybrid system connection during the normal operation and after insertion of a sudden three phase to ground fault on the transmission lines. The investigation will be divided into five sections; section (A) will represent the integration of renewable resources (PV and WF) on the micro grid. Section (B) will represent the PV case before and after the insertion of the BESS at the source side and at the load side. Section (C) will represent the WF case before and after the insertion of the BESS at the source side and at the load side. Section (D) will represent the hybrid system connection after integrating the BESS at the source side and at the load side. Section (E) will represent the hybrid system connection with integrated BESS at the load side and after the insertion of a sudden three phase to ground fault on the transmission lines. Also, an overview on the results showing the effect on the voltage and frequency waveforms before and after the integration of each case will be presented.
