Development of grid connection requirements for wind power generators in India

Grid integration is one of the major concerns in recent years as wind power generation level keeps on increasing continuously in the power system. Therefore, wind farms will have a significant influence on the operation and control of emerging power system, which is expanding in terms of interconnections, network capacity, load demand and addition of new devices for improving the performance of the system. New grid codes are being set up in several countries by specifying the relevant requirements for efficient, stable and secure operation of power system and these specifications have to be met in order to integrate wind power into the modern electric grid. Several states of India have high penetration of wind power and specific grid connection requirements (GCR) for wind power are yet to be established. This paper proposes GCR for wind power integration in India and discusses several technical and operational issues arising due to high penetration of wind power generation in Indian power systems.
