Flexibility Assessment and Strengthening of existing conventional power grids for large-scale renewable energy integration Theoretical/ Modelling based research.
About this project
Power system security is adversely affected by intermittent wind and the variability of solar PV based generation.High penetration of wind and solar can affect three types of stabilities, which need to be comprehensively studied to ensure a secure and highly reliable power system. The figure below shows the steps needed to conduct the research.
To derive the flexibility index of the non-conventional grid in terms of its stability margin. The indexing has to be performed in terms of Small Signal Stability, Transient Stability and Voltage Stability Model.
To develop remedial techniques or methods to improve the grid flexibility, both system-wide and bus-wise.This can be done by developing controllers to enhance the damping of the system. Optimization of the parameters as well as the location of these controllers becomes very crucial in order to have maximum impact without compromising the operational and economic objectives.
To integrate Renewable Energy (RE) Technologies like Solar PV (both rooftop and large-scale) and Wind Turbines to the existing non-conventional grid model to analyze their impact in the system stability and hence, the flexibility of the grid.
To analyze and observe the effect of variations of the penetration levels of RE along with the location of the RE. This will help to establish the relationship between these variations of RE with the change of grid flexibility. This could be instrumental to develop accurate scheduling of the generators and implementing controllers of the renewable integrated grid.
The project outcome will be as below:
Theoretical modelling of stability behaviour of power system with wind and solar PV integrated
Voltage stability analytic tool for renewable energy based power systems.
Comprehensive understanding of small signal and transient stability analytics
Control algorithms for improving system strength for high penetration renewable energy based power systems
Theoretical modelling of frequency response under different critical contingencies
The deliverables from this project, apart from skill development and research training, are high impact publications in reputed journals and international conferences.
