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.
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.
Secondly, to minimize the investment and annual operational and maintenance costs of the photovoltaic–energy storage system, an optimal capacity allocation model for photovoltaic and storage is established, which serves as the foundation for the two-layer operation optimization model.
It is a rational decision for users to plan their capacity and adjust their power consumption strategy to improve their revenue by installing PV–energy storage systems. PV power generation systems typically exhibit two operational modes: grid-connected and off-grid .
And the installed capacity of photovoltaic and energy storage is derived from the capacity allocation model and utilized as the fundamental parameter in the operation optimization model.
The principal studies of PV power generation systems concentrate on two key areas: The optimal capacity of rooftop PV power generation systems and energy storage is being designed [3, 4], and the economic and environmental benefits of the systems are being investigated [5–8].
