Electrochemical energy storage power station dcs

What is electrochemical energy storage (EES) technology?

Electrochemical energy storage (EES) technology, as a new and clean energy technology that enhances the capacity of power systems to absorb electricity, has become a key area of focus for various countries. Under the impetus of policies, it is gradually being installed and used on a large scale.

What is energy storage capacity?

The quantity of electrical energy stored in an energy storage facility plays a critical role in sustaining the operation and functionality of energy storage systems. The power capacity of a facility can be determined by considering its output/input power, conversion efficiency, and self-discharge rate.

What is the revenue of the energy storage station?

The revenue of the energy storage station comprises the earnings obtained from PV system and BESS participating in market transactions (F1), as well as the revenue generated by BESS in the frequency regulation ancillary service market (F2).

What is the initial state of charge (SOC) of a storage power plant?

It is assumed that the initial state of charge (SOC) of the storage power plant is 0.4, with upper and lower operating SOC limits of 0.95 and 0.05, respectively. The charging and discharging efficiency of the storage power plant is uniformly set at 0.95. The details are presented in Table 1. Table 1. Parameters of the battries.

Can energy storage power station operate continuously?

However, due to constraints such as power limits, capacity limits, and self-discharge rates, the energy storage power station cannot operate continuously but rather engages in charging and discharging activities at optimal times.

What is the optimal configuration for energy storage?

The optimal configuration for power and maximum continuous energy storage duration is determined to be 30.99 MW and 4.52 h, respectively. At this configuration, the average daily return is 2.362 × 10 5 yuan and the initial investment cost is 1.45 × 10 9 yuan. Fig. 20. Optimal solution selected by TOPSIS. Table 4. Optimal solution data.
