Can photovoltaic energy storage be used for peak load regulation

Can photovoltaic energy be integrated into the power grid?

To solve the problem of power imbalance caused by the large-scale integration of photovoltaic new energy into the power grid, an improved optimization configuration method for the capacity of a hydrogen storage system power generation system used for grid peak shaving and frequency regulation is proposed.

What happens when photovoltaic power generation cannot meet the load demand?

When photovoltaic power generation cannot meet the load demand, FC (fuel cell) consumes hydrogen to generate electricity (Umachagi et al., 2022) and gains revenue by selling electricity; on the contrary, the surplus power generation is supplied to EC (electrolytic cell) to produce hydrogen, and the proceeds are obtained by selling hydrogen.

Does peak shaving affect the power generation capacity of light-storage-hydrogen power generation system?

To improve the capacity of the light-storage-hydrogen power generation system and its influence on the peak shaving effect of the system, the net load curve is compared between the case of peak shaving and frequency modulation and the case of no energy storage (no peak shaving and frequency modulation), as shown in Fig. 6.

Does energy storage play a role in peak shaving?

This is because the light output without peak shaving and frequency modulation is much higher than that without peak shaving and frequency modulation, and the low net load of the system shows that energy storage plays a role in peak shaving in the system.

Do flexible resources support multi-timescale regulation of power systems?

Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.

Can PSO be used for power grid peak-shaving and frequency-modulation?

Combining the advantages of PSO and the peak-shaving and frequency-modulation requirements of the light-storage-hydrogen power generation system, an improved and optimized configuration method for the power grid peak-shaving and frequency-modulation of the light-storage-hydrogen power generation system is proposed.
