DEWI-OCC, a UL company and wind energy measurement and certification leader, has been accredited for Grid Code Compliance Certification of Renewable Energy Plants according to Indian Central Electricity Authority (CEA) standards. With this certification, DEWI-OCC can assess the performance of power plants against the Low Voltage Ride Through (LVRT) requirement for wind turbines and many additional requirements that apply to most of the power plants producing renewable energy in India.
Grid code compliance certification helps plant owners demonstrate their competence to the relevant grid operators, which gives grid operators the confidence that the new plant operates securely and efficiently.
Grid code compliance requirements differ by country and, in general, are more demanding in those countries with a high penetration of renewable energy. The requirements have evolved from the LVRT requirement for wind turbines to more elaborate ones that apply to renewable power plants in general. In India, the CEA’s ‘Connectivity Standards (2013) for wind and solar generating stations’ stipulate the various power quality requirements with which all grid connected wind and solar power plants must comply.
When connecting a RE generating plant to a network, the plant’s certification must be provided to the grid operator. Certification of grid code compliance is thus mandatory for both manufacturers (unit certification) and for renewable power plant developers, investors and operators (plant certification).
With the Grid Code Compliance certification, DEWI-OCC will review compliance demonstration by power plants. UL can now assess and certify solar power plants, PV inverter units and wind turbines for grid code compliance according to Indian Central Electricity Authority (CEA) standards.
