Solar Wind Hybrid is a concept where both energy sources mutually offset the variations of each other. There are mainly two configurations of Solar Wind Hybrid, DC integration and AC Integration depending on the type of Wind Turbine Generator (WTG) i.e Variable Speed Synchronous Generator (SG) or Doubly Fed Induction Generator (DFIG).
The Hybrid integration is not simply the integration of two systems but requires formulation of design criteria and functionality in terms of control and performance improvement. The objective of the pilot plant installed in Kudgi by NETRA are following
a. Maximize the yield from an identified piece of land and establish the benefits of solar wind hybrid plant over the individual solar or wind plant.
b. Study of effective land utilization by installing the high efficiency solar PV panels in area around wind turbine (WEG) avoiding shadow of the wind turbine.
c. The development of control strategy for active power curtailment (First time in India) when cumulative generation of the solar and wind is above the evacuation capacity
d. Integrating Storage as future project for ramp rate control.
