Grid Connectivity Study is an essential requirement for connecting a Solar or Wind Power Plant to the electrical grid as per applicable CEA requirements.
The study evaluates whether the proposed plant can operate safely and reliably without adversely affecting the grid.
Key studies include Load Flow, Short Circuit, Voltage Stability and Dynamic and Transient Stability analysis.
The study also assesses reactive power capability, voltage control and power factor performance at the Point of Interconnection (POI).
For inverter-based plants, LVRT and HVRT, harmonic distortion, flicker and power-quality performance are important considerations.
Protection coordination and fault-clearing performance are also verified with the grid network.
Different operating scenarios, including maximum generation and N-1 contingency, are normally assessed.
The final study demonstrates compliance with applicable CEA connectivity standards, Grid Code and utility requirements.
A properly executed connectivity study helps ensure reliable evacuation and smooth integration of renewable generation into the grid.
SATCON has experience and resources to carry out such studies.
