What happens if photovoltaic penetration is below 9%?

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.

Is photovoltaic power generation enough to generate energy storage?

According to the above table, when photovoltaic penetration is less than 9%, photovoltaic power generation is insufficient and not enough to generate energy storage. When photovoltaic penetration is between 9% and 73%, photovoltaic power generation is large and energy storage can be generated.

Can energy storage systems reduce the cost and optimisation of photovoltaics?

The cost and optimisation of PV can be reduced with the integration of load management and energy storage systems. This review paper sets out the range of energy storage options for photovoltaics including both electrical and thermal energy storage systems.

What if photovoltaic penetration rate reaches 73%?

When the photovoltaic penetration rate reaches 73%, the combination of photovoltaic power generation and energy storage can fully meet the load demand in the peak period, and there is no need to purchase electricity from the grid, with a surplus.
