Integrity cooperation in low-carbon photovoltaic energy storage system

Is shared energy storage a carbon-oriented planning method for Integrated Energy Systems?

With the development of energy storage technology and sharing economy, the shared energy storage in integrated energy system provides potential benefit to reduce system operation costs and carbon emissions. This paper presents a bi-level carbon-oriented planning method of shared energy storage station for multiple integrated energy systems.

What is the energy-carbon relationship of Integrated Energy Systems?

Firstly, the energy-carbon relationship of the multiple integrated energy systems is established, and the node carbon intensity models of power grid, integrated energy system and shared energy storage station are established. Secondly, a bi-level planning model of shared energy storage station is developed.

What is the capacity planning model of shared energy storage station?

Capacity planning model of shared energy storage station The capacity planning model of SES station includes objective function and constraints, and the specific model is as follows. 3.1.1. Objective function In the upper planning stage, the SES station in the multi-IESs system is to improve the system economy and reduce carbon emissions.

What is a bi-level planning model of shared energy storage station?

Secondly, a bi-level planning model of shared energy storage station is developed. The upper layer model solves the optimal capacity planning problem of shared energy storage station to minimize average emission reduction cost in a long time scale.

Which model is established for integrated energy system?

Node carbon intensity model is established for integrated energy system. Carbon emission reduction model of integrated energy system is developed. Carbon-oriented planning model of shared energy storage is established.

Is energy storage a better option for IES?

Compared with the energy storage planned separately for each IES, it is more economical to provide energy storage services for each IES through SES station, the carbon emission reduction rate has increased by 166.53 %, and the system operation cost decreases by 33.48 %.
