Real-time grid simulation platform for system analysis using virtual power source

A smart grid test bed with 6.6kV experimental distribution network which includes mega-photovoltaic generation systems, rechargeable batteries and so on has been conducted. In order to demonstrate the system performance of smart grid with this test bed, a new simulation platform has been developed. The simulation platform consists of BTB (Back-To-Back), real-time power system simulator and interface controller, and it performs the upper power grid which can reproduce various disturbances such as frequency deviation and instantaneous voltage drop. This paper describes the system configuration, verification test result and application example of this simulation platform.
