PEAK SHAVING CONTROL METHOD FOR ENERGY STORAGE. l: +4621323644, email [email protected] Peak Shaving is one of the Energy Storage applications that has large potential to. become important in the future''s smart grid. The goal of peak shaving is to avoid the installation of capacity to.
When the basic peak-shaving system cannot meet the peak-shaving demand, the energy storage power station and 34 thermal power units in the system participate in the bidding for peak-shaving. The quoted price of the energy storage power station is 600 yuan/MWh.
The peak shaving operation of thermal power units can be divided into two stages: conventional peak shaving and deep peak shaving. According to the operation status, shown in Fig. 1, the load level of a thermal power unit are divided in three range, P1, P2, P3, and when the load level is between P1 and 100%, the unit is in the normal peak …
In case of repeated power peaks the goal of the optimization is to shave only the highest peak of the current month up to now and not each peak of the day, since only the monthly peak is of concern.
