6 FAQs about [Price ratio of photovoltaic power generation and energy storage]

What is the energy storage capacity of a photovoltaic system?

Specifically, the energy storage power is 11.18 kW, the energy storage capacity is 13.01 kWh, the installed photovoltaic power is 2789.3 kW, the annual photovoltaic power generation hours are 2552.3 h, and the daily electricity purchase cost of the PV-storage combined system is 11.77 $. 3.3.2. Analysis of the influence of income type on economy

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.

What is the relationship between photovoltaic penetration and electricity purchase cost?

According to the known data, without considering the photovoltaic cost and benefit, the cost of purchasing electricity can be obtained as shown in Table 6. Table 6. Relationship between photovoltaic penetration and electricity purchase cost (1%–9%). When photovoltaic penetration is between 9% and 73%, energy storage can be carried out.

What is the optimum charging power for a solar PV plant?

The optimum charging power is close to 80% of the PV plant nominal power, whereas discharge (stored energy + gas fired extra) power is slightly less (∼70%). Regarding storage capacity, the optimum is found for almost 12 h.

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.

Does a photovoltaic energy storage system cost more than a non-energy storage system?

In the default condition, without considering the cost of photovoltaic, when adding energy storage system, the cost of using energy storage system is lower than that of not adding energy storage system when adopting the control strategy mentioned in this paper.
