Reliability - from Load Forecasting to System Operation in Indian Power System

In this paper, in the background of evolution of power grids in India, establishment of regulatory framework and operational philosophy in vogue, first reliability aspect of long term, mid term as well as short term (operational / outage) planning has been dealt with. Thereafter issues on the day ahead scheduling of generation as associated with real time operation (linking frequency in particular) for implementation through unique real time pricing mechanism has been highlighted. It has been shown how effectively markets could take care of reliability with self-healing mechanism, particularly in a country like India having power shortages. At the same time important parameter like grid voltage too has figured in, although a lot more is expected in the time to come. Though immediately not tagged with pricing in the power market directly, finally grid security, restoration, mock trial for black start, etc. from reliability angle are the other pertinent aspects that have been touched to conclude. As such reliability coordination in every aspect is playing an important role right from load forecasting to system operation under the changing scenario with the development of power market in India[1].
