Outline Introduction Current status and Challenges Proposed placement of the super-capacitor Result & Discussion Conclusions

Introduction - Background Solar Array DC/AC Load Charge Controller Inverter Battery

Current Status and Challenges The battery size in a stand-alone PV system is calculated for the average annual data, also for at least three days of island autonomy, as a result: 1. The daily quick changing in PV output is not dependable. 2. The battery life reduced dramatically due to quick charge discharge. Challenges Achieving more effective energy management techniques in a stand-alone PV system by implementing the super capacitor to deal with the rapid change.

Proposed placement of the super-capacitor

Conclusions This paper discusses an incorporation of the super-capacitor as secondary storage unit in a stand-alone PV system. Three cases was generated to present and validate the proposed energy management algorithm in the stand-alone PV system with implementing a super capacitor. Super-capacitor behaviour under various load , with higher fluctuation in the generated power by the PV system. Fast changing in the load or the generated energy has been belt by the super-capacitor.
