However, if hydrogen is produced by reducing the amount of electricity connected to the grid, the overall benefits of the photovoltaic power plant will be lost. Thirdly, energy storage can bring more revenue for PV power plants, but the capacity of energy storage is limited, so it can't be used as the main consumption path for PV power generation.
If photovoltaic power stations want to utilize excess electricity through hydrogen production or energy storage, the cost and profit of hydrogen production and energy storage need to be considered. When the cost is less than the profit, investment and construction can be carried out.
Finally, this study takes the data of a photovoltaic power station in Shanghai as an example for calculation, and the results show that photovoltaic grid connection is currently the main source of benefits, blindly increasing energy storage and hydrogen production is uneconomical.
Without considering photovoltaic hydrogen production and energy storage, the main profit of photovoltaic power generation enterprises comes from grid connection, but it is limited because the characteristics of power generation and technological level. At this point, the maximization of value has not been achieved.
Grid connection is the main source of profit for photovoltaics, but the amount of electricity that can be connected to the grid is limited, most newly built photovoltaic projects in China's provinces and cities have already achieved grid parity, and the future grid electricity prices may be even lower.
The simulation test also reveals the important role of energy storage unit in power grid demand peaking and valley filling, which has an important impact on balancing the instability of photovoltaic power generation and improving the system response ability. 1. Introduction
