Currently, because of the income only coming from frequency regulation, the annual average charge and discharge power is only 50.05% of the optimal value, so the total income of BESS for frequency regulation and peak regulation decreases rapidly with the
Eq. 1a is the quadratic coal consumption cost of TPU i at the time t, where P i, t g is the power output; a i, b i, and c i are the cost coefficients. Eq. 1b approximates the tear-and-wear cost of TPU based on the commonly used Manson-Coffin formula, where β is a cost conversion coefficient; S i g is the overall investment cost of TPU i, and N f (P i, t g) is the …

Fig. 2 shows a comparison of power rating and the discharge duration of EES technologies. The characterized timescales from one second to one year are highlighted. Fig. 2 indicates that except flywheels, all other mechanical EES technologies are suitable to operate at high power ratings and discharge for durations of over one hour.
The Energy Generation is the first system benefited from energy storage services by deferring peak capacity running of plants, energy stored reserves for on-peak supply, frequency regulation, flexibility, time-shifting of production, and using more renewal resources ( NC State University, 2018, Poullikkas, 2013 ).
On this basis, we propose a flexibility enhancement method coordinating battery energy storage capacity optimization and deep peak regulation of thermal generators, which aims at minimizing the total investment and operation costs while satisfying operating constraints on representative days.
