European and Indian Grid Codes for Utility Scale Hybrid Power Plants

The aim of this paper is to review and compare present European and Indian grid code requirements imposed to hybrid power plants (HPPs) combining wind, solar and storage technologies. Since there are no grid codes specifically for HPPs, the paper will review grid codes for the power plant based on individual renewable technology in the HPP. European grid codes specifies ranges for parameters inside which each national transmission system operators (TSO) has to specify the set of national parameters (Danish specifications in this paper). The comparisons are performed with respect to fault-ride-through capability, frequency and voltage operation ranges, active power control/frequency support as well as reactive power control/voltage support.

Automated summary

This paper reviews and compares grid code requirements for hybrid power plants in Europe and India, focusing on fault-ride-through capability, frequency and voltage operation ranges, as well as active and reactive power control.
