Improved Bidirectional Converter for PV System with Battery Storage

Solar energy is the most popular renewable energy source in the recent times. The use of solar energy for electricity generation is limited and it's non- continuous availability makes the solar power unreliable for critical applications. These problems can be overcome by using other resources in parallel with the solar energy and making it to operate when the solar power is not available. One such solution includes the usage of Hybrid Energy Storage System along with solar power. HESS has different configurations and includes different resources. Here the battery is used as a backup source along with solar. The battery gets charged during the time when solar power is available and the load is supplied by the battery storage while the solar power is unavailable. This system is discussed in detail in this paper. The power flow in both the direction will be controlled by the bidirectional converter. This paper also discusses the simulated results of this proposed system in detail.
