Improvements in the Development of Grid Code and Review of Power Quality Requirements for Fluctuating Wind Power Generation in India

This paper deals with the improvements in the Indian grid code and the important point in the power quality requirements. It reviews the Indian grid code and the grid code requirements for wind energy conversion systems and the modifications in the Indian wind energy grid code is presented for further improvements. Power quality issues and requirements in the grid integrations are briefly explained. The main objective of the power quality review is to study the basics of power quality, standards, measurements and the devices used to improve the power quality. The current The International Electrical Commission (IEC) standards were described and the measurements standards are presented. The power quality problems associated with grid integration like voltage fluctuations or flicker; harmonics and interharmonics; voltage drops; active power; reactive power; grid protection and reconnection time are studied and the implementation of the measurement and assessment procedures, specified by the various standards are discussed.
