Self-healing Grid
Power System Studies Related With Self-healing Grid
Our Advanced Real-Time Power System Analytics (ARTPSA) provides excellent real-time analytics solution with the ability to sense, analyze, learn, decide, and responds to any changes in the power grids for ensuring continuous compliance of N-1 criterion. Our ARTPSA performs real-time contingency analysis, screens insecure contingencies and supplies the power system operators with rapid, effective, and economically sound recommendations for control actions to address transient stability, voltage stability, and thermal security.
In addition, our ARTPSA studies also offers feasible preventive and enhancement control recommendations to mitigate risk without the need for load shedding and enable increase in load margins where such margins are judged insufficient. An effective real-time corrective control action for critical contingencies is available to increase the load margin by exercising all the following Level-1 control actions which are no-cost controls and low-cost controls before resorting to load shedding.

Transmission Smart Grid Applications For Self-healing Grid
In this focus area, we conduct studies on the enhancement of the network reliability to ensure the reliability and security of power supply. In general, the self-healing grid will dynamically optimise the performance, capable in automatically anticipating and responding to disturbances, reduce recovery time when unexpected disturbance actually occurs, and continually optimizing its own performance.
