Seminar Series at Kollam
Seminar Series on ‘Grid connectivity of renewable energy: issues and solutions’ organised by the KSEB Engineers Association and the Kerala Chapter of the Institution of Electrical and Electronic Engineers was held at the T K M College of Engineering, Kollam on 14/02/2013.Er S Manoj, Executive Engineer, Punalur presided over the function.
K. Radhakrishnan, former KSEB Member (Generation), has said that given the peculiarities of the Kerala power system, any decision on large-scale grid connection to seasonal resources such as solar and wind power plants should be taken cautiously to maintain the power system security, while inaugurating the seminar In comparison to the neighbouring States, the Kerala power system was very small and could not withstand the sudden withdrawal of seasonal energy resource if it exceeded 10-15 per cent of the total sources. With very high per cent of domestic load in Kerala, which stood at around 50 per cent compared to 30 per cent in other States, the load curve was very steep. A load curve was a chart showing the amount of power consumers use over a period of time. The load increases by two or three fold in the evening hours and without effective measures to flatten the curve, power generation would become uneconomical. Allowing large-scale connectivity to solar power would make the situation worse as the day load would be further reduced and evening load would be increased. Solar and wind power being infirm called for more investment to install backup power for an equal amount, he said.
Prof Mohamed Kassim, in his key note address has called for the necessity of introducing modern concepts like Smart grid into the Kerala System to deal with complexities that may arise with wide spread grid connectivity. Er Cherian Varghese former Chief Engineer has called attention to the need of economizing the KSEB functions. Er T Syed Ali, the district Secretary welcomed the gathering and Er Edwin Callistus proposed vote of thanks.
