Development and Field Test of Movable Conduction-Cooled High Temperature SMES

With the large scale renewable energy being put into utility power system, the active power imbalance becomes one of the major problems. The novel power system stabilizer (PSS) based on energy storage system (ESS) seems to be a potential solution to mitigate fluctuation of both power generation and consumption. Superconducting magnetic energy storage system (SMES) is getting increasing acceptance in various applications of power system for higher efficiency and faster response than other ES devices. This paper introduces the development of a movable conduction-cooled high temperature SMES module as potential energy storage system. For utility power system use, the developed SMES system is with the feature of movable, high temperature superconducting (HTS) and conduction cool. Laboratory experiments including operational characteristics and improvement of power system stability have been carried out. Field experiments have also been carried out in Laohukou hydro power plant in Hubei province of China. Results of both laboratorial and field tests demonstrate the well design and manufacture of the developed movable SMES module.
