Can energy storage make off-grid photovoltaic hydrogen
Considering the intermittence and variability of PV power generation, the deployment of battery energy storage can smoothen the power output. However, the investment cost of battery energy storage is pertinent to non-negligible expenses. Thus, the installation of energy-storage equipment in a PVEH system is a complex trade-off problem.

The capacity allocation method of photovoltaic and energy storage
When the photovoltaic penetration is below 9%(Take the load curve on August 2 as an example), the photovoltaic power generation is not enough to generate energy storage (the photovoltaic power generation is far lower than the load demand, so there is no energy storage, that is, no PV abandoning). The schematic diagram is shown in Fig. 9 below.
