[PDF Version]FAQS about Price of energy storage capacity of photovoltaic power station
What is the energy storage capacity of a photovoltaic system?
The photovoltaic installed capacity set in the figure is 2395kW. When the energy storage capacity is 1174kW h, the user's annual expenditure is the smallest and the economic benefit is the best. Fig. 4. The impact of energy storage capacity on annual expenditures.
Why is energy storage important in a photovoltaic system?
When the electricity price is relatively high and the photovoltaic output does not meet the user's load requirements, the energy storage releases the stored electricity to reduce the user's electricity purchase costs.
What determines the optimal configuration capacity of photovoltaic and energy storage?
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.
Does photovoltaic installed capacity affect peak-to-Valley price difference?
In order to further analyze the relationship between the user's annual comprehensive cost, photovoltaic installed capacity, and peak-to-valley price difference, different scenarios are set for comparative analysis. Under the current time-of-use electricity prices, change the installed capacity of photovoltaic.
Does energy storage capacity affect annual comprehensive cost?
The annual comprehensive cost is positively related to energy storage capacity when adopting pricing scheme 1, namely when the peak-to-valley price difference shrinks to a certain extent, consumers cannot obtain economic benefits by configuring energy storage.
How to increase the economic benefits of photovoltaic?
When the benefits of photovoltaic is better than the costs, the economic benefits can be raised by increasing the installed capacity of photovoltaic. When the price difference of time-of-use electricity increases, economic benefits can be raised by increasing the capacity of energy storage configuration.
