Abstract

Abstract: ABSTRACT： In some parts of our countrys northwest area, the wind and solar energys abandoned phenomenon is severe now which has become one of the main factors to restrict the renewable energys development. With the rapid development of electrochemical energy storage technology, the time-space power characteristics of large scale energy storage system can rich the grids peak shaving means, improve the reliability of power supply, thus the renewable energys given ability of the northwest region will be improved. This paper analyzes the northwest power grids new energy absorption firstly, and proposes the large scale energy storage systems application scenarios in the northwest power grid. Then, based on the actual structure and operation data of Xinjiang, Gansu and Qinghai power grids, the simulation of the large scale energy storage system participated in frequency and voltage regulation is conducted. Based on the simulation result, the storage systems configuration scheme and investment benefits are concluded. The research results can provide a reference basis for the large scale energy storage systems investment and operation in northwest region.

Key words: KEYWORDS： northwest area, wind energys abandoned rate, large-scale energy storage system, renewable energy absorption
