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.
What is the quantification model of power system peak-shaving cost?
According to the typical daily renewable energy and load characteristics of Ningxia region, the quantification model of power system peak-shaving cost is established. The model takes into account the time-of-use electricity price factor. The objective function is to minimize the total peak-shaving cost of power system.
Do pumped storage hydropower plants affect peak-shaving cost of nuclear power?
The model completed the quantification of the peak-shaving cost of nuclear power. A method to determine the scheduling of the pumped storage hydropower plants to have the maximum impact on peak-shaving and valley filling, considering the daily generation scheduling program of the thermal units in Iran power grid was proposed in .
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”.
What is the paid peak-shaving standard of thermal power units?
The paid peak-shaving standard of thermal power units is 50 % of their rated capacity. Deep peak-shaving trading adopts unilateral centralized bidding party of thermal power enterprises to pre-clear and officially clear in real time.
