Finding a reasonable capacity configuration of the energy storage equipment is fundamental to the safe, reliable, and economic operation of the integrated system, since it essentially determines the inherent nature of the integrated system .
Multi-timescale energy storage capacity configuration approach is proposed. Plant-wide control systems of power plant-carbon capture-energy storage are built. Steady-state and closed-loop dynamic models are jointly used in the optimization. Economic, emission, peak shaving and load ramping performance are evaluated.
In the uppermost capacity configuration level, the capacities of energy storage equipment are optimized considering the investment costs and the feedback of operating performance of the entire plant. The candidate capacity is sent to the operation optimization stage as reference device capacities.
Each part of the energy storage power station contributes. The pumped storage system handles relatively slow power fluctuations. Lithium batteries allocate the power portion between high and low frequencies. The supercapacitor mainly takes on the high-frequency part where the frequency change is the fastest.
Specifically, referring to the frequency deviations and the limitations of the dead zone, the energy storage system determines its output duration and action magnitude. This control function can be implemented using multiple power conversion systems (PCS) for energy storage.
When the frequency fluctuates, energy storage stations can swiftly respond to the frequency changes in the power system, offering agile regulation capabilities and maintaining system stability [ 10 ]. Thus, the participation of energy storage stations is also crucial for ensuring the safety and stability of operations in the power system [ 11 ].
