How many provinces have a peak to Valley electricity price difference?
The State Grids and China Southern Power Grids of 29 provinces, autonomous regions and municipalities announced the electricity tariffs for industrial and commercial users in December 2021. According to the statistics, 14 provinces and cities have a peak to valley electricity price difference that exceeds 0.7 yuan/kWh.
Does energy storage affect peak-shaving cost?
On the other hand, references [35, 36] do not consider the impact of energy storage utilizing peak and off-peak electricity price arbitrage on the peak-shaving cost of the power system, thus failing to fully utilize the peak-shaving capabilities of energy storage.
Does PvP increase electricity price during peak periods?
This is because the optimized PVP policy increases the electricity price during peak periods. The current policies in Types I and II provinces are less effective in peak shaving, with only a 1.9%–3.2% reduction in peak load, while those in Type III provinces appear to be very effective in peak shaving.
How does time-of-use electricity price affect energy storage?
To analyze this phenomenon, we can observe the charging and discharging periods of energy storage in Fig. 8, Fig. 11. The time-of-use electricity price makes the price gap between peak, flat and valley periods large, and has the role of guiding energy storage to “cut peak and fill valley”.
Are electricity pricing policies effective in peak shaving and valley filling?
The focus of power companies is on the variation in the effectiveness of electricity pricing policies in peak shaving and valley filling (Fig. 14). Overall, the current PVP policies in 11 provinces except Gansu are ineffective in peak shaving but are somewhat effective in valley filling.
How do energy storage power stations work?
Driven by the peak and valley arbitrage profit, the energy storage power stations discharge during the peak load period and charge during the low load period. They play the role of “cutting peak and filling valley” and realize the full utilization of energy storage resources.
