Abstract: |
The Indian power system underwent two separatemassive blackouts on 30th and 31st of July 2012.These blackouts exposed a series of inherent problems underlying the power system of India, such as its generation planning, transmission planning, grid infrastructure,management systems, primary energy resources, environmental constraints, electricity market, and informationtechnology, which together aggravate the massive blackouts.These factors which affect the adequacy and securityof the power supply in a similar manner as the transmission congestion of physical grids does, can be called by ageneric term as generalized congestion. Competitive manipulations and ‘‘game-playing’’ between variousinterested parties further intensifies these congestions.Here, from the perspective of generalized congestions, the paper reflects the inevitability of India’s massive blackouts,discusses occasional effects of trigger events, inherentevolution law of blackouts and the enlightenment on power industry in China, and explores risk control measures to defend blackouts in China. The positive role of strongsmart grid in insuring energy and environment security ishighlighted. |
