What is a reasonable capacity configuration of energy storage equipment?
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 .
Does energy storage play a role in operating practice?
A comprehensive index including both the long-timescale economic, emission, peak load shifting performance, and the short-timescale dynamic load ramping performance is designed to evaluate the full roles of energy storage in operating practice.
Do energy storage technologies improve economic performance?
From the viewpoint of totalized costs, the deployments of energy storage technologies all improve the economic performance of the integrated system. It can be observed that the investment costs of BESS are the highest among the three energy storage technologies due to the high price and short design lifetime.
Why do load agents need to compare energy storage options?
RESS has the advantages of large capacity in electricity and long sustainable time in power, but high maintenance costs and recycling costs. Load agents need to compare different energy storage options in different power markets and energy storage trading market scenarios, so that they can maximize economic benefits.
What is energy storage capacity optimization?
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.
What is a multi-timescale energy storage capacity configuration approach?
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.
