ABSTRACT: Integrating wind renewable into traditional grids started accelerating in early 2000’s followed by large solar farms much recently. Conventional generation are all synchronous based technology while the renewable farms that are not based on traditional machines were treated with simplistic models for grid security planning, analysis and operation. Nirmal has contributed towards proposing and validating realistic and effective large-scale wind farm models. In 2008 NZ was about 70% renewable with primarily synchronous generation from hydro and geothermal and approximate model was fine but with increasing contribution more realistic coherency-based model proposed was found useful. Special contribution also extends to development of two separate grid ride through characteristics for New Zealand as its power systems have two island networks separated by HVDC lines particularly relevant now with around 88% renewable NZ grid and having separate allowable frequency bands. These contributions on ride-through and load-shedding schemes as applied to NZ grid has informed wind farm ride-through grid codes and extended reserves design by NZ Electricity Authority. NZ relevant IEEE publications, CIGRE reports, inputs to NZ Electricity Engineer’s Association guides and mentoring PhDs, Masters and undergraduates in this area has enabled new technical skills and capabilities to the workforce.
