Optimized configuration of centralized energy storage system

What is energy storage optimization?

Secondly, the optimization goal is to maximize the annual net income of the energy storage system and minimize the cost of electricity per kilowatt-hour, and the key operating status is used as the constraint condition to establish an energy storage optimization configuration model.

Can IES configuration be optimized based on multiple energy storage?

This work focuses on the optimization of IES configuration based on multiple energy storage, taking into account risk assessment by decision-makers.

What are the different energy storage modes?

Two energy storage modes, battery type and pumped storage, are comprehensively considered. Take an actual regional power grid as an example test system, and use an improved particle swarm algorithm to solve the optimization model.

Does integration of multiple energy storage units improve system reliability?

The results indicate that the integration of multiple energy storage units into the system reduces carbon dioxide emissions by 2.53 % and fossil energy consumption by 2.57 %, improving system reliability by 0.96 %.

What is a system optimization model?

The proposed optimization model provides an effective tool to determine the system configurations while balancing economic benefits and system robustness according to the risk tendency of decision-makers. The main conclusions are as follows:

What are the benefits of integrating energy storage units in a system?

Gas turbine, absorber and power grid increase the robustness of the system against the risk of source-load uncertainties. The integration of energy storage units in the system reduces CDE by 2.53 % and fossil energy consumption by 2.57 %, while also improving system reliability by 0.96 %.
