This paper firstly reviews the recent development in power system protection, with special attention paid to the wide-area and integrated protection, in order to look into future development of protection and control system for smart grids. The paper then mainly reports on the design of a novel architecture for the integration of protection and control for wide area power network. The concept of integrated...
Energy storage system is necessary to maintain steady operation of the micro-grid and decrease its influence on the distribution grid. This paper mainly presents the research on the composite energy storage system in a wind and PV hybrid micro-grid. The energy storage system is composed of a battery and a super-capacitor, which combines advantages of both sides. The battery is supposed to compensate...
This paper presents an integrated PMU and protection scheme for power systems. The scheme integrates local and wide area control and protection systems by implementing the WAMS function and substation protections into one system to identify the overload caused by flow transfer from isolation of main trunk line. This integrated system mainly consists of three major components: local interface unit...
Cascading overload trip due to lack of transmission section protection is an important reason of large-scale blackout. This paper illustrates the meaning of transmission section and points out that the objective of transmission security protection is to maintain its integrality and transmission capacity, and to avoid cascading overload trip. In addition, the implement condition and key technology...
