Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid. The application of the system will determine the system’s configuration and size. Residential grid-connected PV systems are typically rated at less than 20 kW.
In the design of the “photovoltaic + energy storage” system construction scheme studied, photovoltaic power generation system and energy storage system cooperate with each other to complete grid-connected power generation.
Particularly at high PV penetration levels, PV systems should maintain grid connectivity through reactive power injection in reaction to voltage faults to prevent instigating extreme incidents, such as blackouts. To further reduce the cost of energy, it is necessary to enhance both dependability and efficiency.
Although Li-ion battery is commonly used in most cases, with better economic and environmental performance over PbA battery and Vanadium redox flow battery , other energy storage methods are also discussed in the current studies, especially for hybrid storage system in distributed PV system.
A 50 MW “photovoltaic + energy storage” power generation system is designed. The operation performance of the power generation system is studied from various angles. The economic and environmental benefits in the life cycle of the system are explored. The carbon emission that can be saved by power generation system is calculated.
