6 FAQs about [Peak-valley electricity price and energy storage]
What is the difference between Peak-Valley electricity price and flat electricity price?
Among the four groups of electricity prices, the peak electricity price and flat electricity price are gradually reduced, the valley electricity price is the same, and the peak-valley electricity price difference is 0.1203 $/kWh, 0.1188 $/kWh, 0.1173 $/kWh and 0.1158 $/kWh respectively. Table 5. Four groups of peak-valley electricity prices.
What is a deep valley electricity price mechanism?
Where cogeneration units and renewable energy have a large proportion of installed capacity, and where the contradiction between phased oversupply and demand in the power system is prominent, a deep valley electricity price mechanism can be established concerning the peak electricity price mechanism.
What happens if the peak-valley electricity price difference decreases?
As the peak-valley electricity price difference, annual average irradiance and annual average wind speed decrease, the optimal allocation capacity and the annual net revenue of the BESS also decrease.
How to improve peak-valley price mechanism?
1. Improve the peak-valley price mechanism. l Scientifically divide peak and valley periods. All localities should consider the local power supply-demand status, system power load characteristics, the proportion of new energy installed capacity, system adjustment capabilities, and other factors.
How can centralised energy storage reduce peak-valley price arbitrage?
In addition to reducing the peak-valley difference of transformer stations, additional centralised energy storages will be allocated to realise peak-valley price arbitrage when the investment of centralised energy storage units is not less than 1400 yuan/kWh and no more than 1600 yuan/kWh.
What should be considered when determining the peak-valley price?
Where the proportion of installed renewable energy power generation capacity is high, full consideration should be given to the fluctuation of new energy power generation output and the changing characteristics of the net load curve. l Reasonably determine the peak-valley price.
