Ravi and others Outcome of the Event Workshop on “Grid Security and Management” Indian Power Sector is currently passing through evolutionary phase and there are numerous challenges that Power Sector is presently facing. The first and foremost challenge in this regard is the adequacy of power supply and to meet the same we need to add more than 80000 MW capacity by the end of the current plan i.e. by 2012 as against the present capacity of about 41000 MW we have been able to add during more than last 5 decades of operation. Further, even after adding this large capacity, wheeling it to the distant locations to ultimately reach the end consumer would be possible only if commensurate growth in the transmission sector matching with that of generation capacity addition is achieved simultaneously. In this direction a large number of interstate and interregional transmission links have been added in the different areas of the country in the recent past and that has made it possible to have seamless flow of power from surplus to deficit areas and meeting the overall higher demand due to diversity of load factor. However this addition of the transmission network has also brought with it a variety of operational, commercial and techno-economical issues and have thrown fresh challenges to the grid operators in the form of heavy loading of the lines, skewed load-generation pattern etc. The above complexity and the challenges emphasizes the need for adopting fast and reliable grid security measures and use of modern and intelligent technologies to manage the vast network in an integrated mode of operation. In order to address all these issues, a two-day workshop on ‘Grid Security and Management’ was organized by POWERGRID in association with KPTCL and IEEE Power Engineering Society, Bangalore Chapter at the National Institute of Advanced Studies (NIAS), IISc. Campus, Bangalore on 28th and 29th April 2008. It was a very informative and interactive two-day workshop attended by over 150 delegates from power utilities, industry, regulatory agencies, academic and research institutions. Hon’ble Justice Santhosh N.Hegde, Lokayukta, Government of Karnataka was the Chief Guest at the inaugural function at the workshop on 28th April 2008. During the inaugural address Hon’ble Lokayukta, Justice Santhosh N.Hegde delivered a strong message to the participants to perform the duty with a high sense of commitment and spirit towards public service and stated that the ultimate objective of all power utilities must be to improve the electricity supply to needy and poor. Justice Santosh N.Hegde also said that distribution of electricity should be taken on with the ordinary citizen in mind, with a special focus on rural and economically weaker sections of society. Dr. P.K. Shetty, Professor & Dean, NIAS and Director, (POWERGRID) while delivering the inaugural address and introducing the theme of the workshop to the participants emphasized that the economy in India is growing at a fast pace and electrical energy has become one of the prime movers in this process. To accomplish this, the nation has set itself a target of providing access of electricity to all household by the end of 11th plan i.e. end of 2012 by increasing per capita electricity consumption from current level of around 650 to 1000 units. The desired goal however can be achieved only with the concerted and all out efforts by all the players associated with the electricity industry. Dr. P.K.Shetty informed the participants that in addition to bridging the demand-supply gap in the country which is of the order of 13-14% during the peak period and 9-10% in terms of daily energy, another most important challenge in front of us is to manage the safety and security of the grid. He added that the theme of the workshop “Grid Security and Management” is truly representative of the importance of this subject in today’s context and wished that the two-day workshop shall have very useful interactive sessions and at the end of the workshop we will be able to come out with some useful resolutions, which may be of further help in managing the safety and security of the grid.

With the passage of time, Indian Power Sector has grown from isolated system around urban and industrial areas to State Grid systems during 50s and 60s. The concept of Regional Grid was initiated in the year 1964 and the Regional Grids were consolidated during 70s and 80s with the main objective to achieve power evacuation and supply to area load centres in the region and ensure reliability of supply. In late nineties the focus was shifted towards National Grid with the objective to harness hydro resources in Himalayan and NER regions and the coal (thermal) in ER region on all India basis. It was accompanied with the phased development of corss-regional transmission system with long term perspective to address Right of Way (ROW) and corridor congestion issues. To deliberate on the above issues, immediately after the inaugural function in the morning session, Mr.V.Ramakrishna, Member (Power Systems), CEA unfolded before the delegates the growth of power system in the country and the future perspective. The challenges in power system planning on account of uncertainty in load growth, changes in generation programme, ROW constraint and utilization of hydro potential in the north-east were explained. The need for rationalizing the transmission tariff to encourage investment in transmission was also emphasized by him. Mr. R.N.Nayak, ED (Engineering), POWERGRID while delivering the talk on ‘Emerging Technologies in Transmission System’ during the poast-lunch session, deliberated upon the status of present transmission network which include about 78,000 circuit kms. Of 765/400 KV lines and 115,000 ckt. kms. of 220/132 KV lines spread across the length and breadth of the country. He added that presently the inter-regional capacity in India is more than 17,000 MW which is going to be over 37,000 MW by the end of year 2012. Mr. R.N.Nayak also deliberated in great detail about the need for new technology in transmission sector in order to attain the rapid growth. He reiterated that to achieve this, focused attention is being given in all stages of transmission system including planning, design, construction, operation and maintenance and grid management. Mr. R.N.Nayak was of the firm view that the desired growth in the transmission sector, matching with that of generation capacity addition can be achieved only if high priority is given to R&D efforts to develop the new technology and in this regard he appraised the participants the significant work done by POWERGRID in the recent past which include implementation of FACTS (Flexible AC Transmission System) for increasing the power transfer capacity of existing lines, building of 800 KV AC system, multi-circuit/multi conductor line, high-rise/compact/pole type towers and commissioning of GIS (Gas insulated sub-stations) for optimal utilization of space. In the next post-lunch session chaired by Mr.S.Majumdar, Director (Projects), POWERGRID there were four presentations:
The respective speakers in their presentations deliberated upon the ways and means to bring-in the economy and efficiency in the power sector in the country. Mr.V.K.Agrawal discussed in detail the logistics associated with the open access in transmission, its journey since inception, issues associated with it and the way-ahead. Prof.D.P.Sen Gupta presented the case-study pertaining to achieving of the energy saving by advancing the Indian Standard Time by half-an-hour. Mr.Atul Shah made a lucid presentation on the current scenario in respect of the wind energy in the country, its connectivity to the grid and the main issues faced by wind form developers. Mr.Pratap Kumar presented the scheme and action plan for the distribution system automation they are planning to carry out in Karnataka’s transmission and distribution system and the likely advantages Karnataka would get with such measures. All these presentations were highly interesting and interactive and were well received by the participants. At the end of the first day’s session a play “Dharma Bhoomi’ by the group ‘Prabat Kalavidaru’, Bangalore was staged which was immensely enjoyed by the participants and it was followed by the dinner. The second day of the workshop started with the key note address by Dr. R.P. Singh, CMD, POWERGRID. In fact, Dr.R.P.Singh, Chairman and Managing Director, POWERGRID was also scheduled to be present during the inaugural function to deliver the key note address. However at the last moment due to some official responsibilities Dr. R.P. Singh, CMD, POWERGRID had to reschedule his programme and he delivered the key note address on the 2nd day of the workshop. In his address Dr. R.P.Singh delivered an inspiring and thought provoking talk and stated that all power engineers must gear up to meet the challenges arising out of the very significant role which electricity has assumed in the present conditions. He also appraised the participants with the initiative and host of actions POWERGRID has taken in the past to expand and strengthen the transmission network in the country and concluded his address with the quote by Churchill that “As long as we have faith in our own cause and an unconquerable will to win, victory will not be delivered to us”. During the pre-lunch session, the address by CMD, POWERGRID was followed by invited talks on:
The talk on ‘Environment and Electricity Power Generation’ by Prof. J.Srinivasn generated lot of curiosity and interest amongst the participants. Prof. J.Srinivasan shared with the participants that during the 20th century there has been a remarkable increase in electric power generation by the burning of coal, oil and natural gas, causing a large increase in the amount of carbon-dioxide in the atmosphere. He added that the increase in greenhouse gases like carbon-dioxide and methane have caused the global mean temperature to increase by 0.7 degrees centigrade and if the electricity generated by power plants (by burning fossil fuels) in the 21st century increases at the same rate as in the 20th century, then the global mean temperature may increase by 2 to 4 degrees centigrade. This can lead to more extreme weather events, rapid melting of glaciers, and increase in seas level. It was emphasized that there is an urgent need to look for anew methods of electric power generation including wind and solar power that do not cause an increase in carbon dioxide. Prof. J.Srinivasan was also of the view that though these technologies are expensive at present, but can become economical if techniques of mass production are employed. Shri Bhanu Bhushan, Member, CERC delivered a talk on the Electricity Market Design in Indian Context and shared with the participants with the journey of electricity grid in the country during last few years. He deliberated in detail about the adverse grid parameters which prevailed in the past for sustained durations, the primary causes for the same and the effects of these on the consumers and electricity industry. He also appraised the participants with the noble commercial mechanism in the form of Availability Based Tariff (ABT) implemented in the country in order to address a large number of issues and the achievements after the implementation of the same. Mr.Bhanu Bhushan also emphasized on the further works required to be carried out in the electricity sector which include linking of incentives to thermal generation with plant availability instead of PLF, rationalization of tariff structure in respect of hydro plants, payment security for unscheduled interchanges and implementation of intra-State ABT, etc. Shri S.K.Soonee made a detailed presentation on the Grid Operation and Control – Issues, Concerns and Expectations. He outlined the growth story in Indian Power sector in the fields of generation, transmission and interconnection, the modernization at the Control Centres, evolving power market and the main concerns faced by the sector as a whole. He also deliberated in detail on the issues related with power system reliability, impact of unforeseen inclement weather conditions and associated factors on the grid. Mr.S.K.Soonee shared with the participants about the tools for visualization and situational awareness being used in the grid operation and also about the balancing market in the electricity industry. Each of the above session was highly informative and interactive and covered the specific issues and desired action plays on the respective subjects in good detail. The post lunch session chaired by Prof. P.S.Nagendra Rao, IISc.,. Bangalore had three presentations on :
Dr.R.Nagaraja in his presentation defined the electric grid and elaborated the need for creation of intelligent grid. The performance metrics associated with the integrated grid are reliability, power quality, security, economy, environmental implants, efficiency and sustainability. The presentation by Dr.R.Nagaraja highlighted the two specific metrics the grid security and economy in details. In his presentation Mr.Sethuraman Ganesan elaborated on the importance of Wide Area Monitoring (WAM) system in real time monitoring of the power system. Unlike estimation of the system state which was being done in the past, WAM results in better visibility and control of the system. Mr. Sethuraman Ganesan stated that automatic high speed control of the grid through using WAM is an evolving model in many systems worldwide. Mr. M.M.Babu Narayanan in his presentation addressed the issues involved in the secure operation of power system and explored the application of some of the standard Knowledge Management techniques such as knowledge portals, mentoring, etc. to enhance the performance of the system operators. All above were focused talks and very relevant to the central theme of the workshop and were highly appreciated by the participants for their value and contents. A panel discussion on the topic of the workshop was held in the concluding session. The session was Chaired by Mr. Bhanu Bhushan, Member, CERC and other eminent personalities were present which include Dr. A.K.Tripathy, former DG, CPRI, Dr. P.K. Shetty, Professor & Dean, NIAS and Director, POWERGRID, Dr. S.A.Khaparde, IIT, Mumbai, . Shri S.K.Soonee, ED (SO), POWERGRID and Shri D.G.Sohony, ED, SRTS-II, POWERGRID.. During the panel discussions the participants raised variety of questions ranging from the grid security and control, open access in transmission, regulatory principles and the problems faced by them in following certain situations as contained in the Indian Electricity Grid Code and other such statutory documents. Some of the participants also brought to the attention of panelists their experiences and difficulties in respect of certain short term open access cases they had applied in the recent past and their suggestions to amend the regulations to take care of such issues. A large number of questions were also raised relating to the existing tariff in case of transmission/STOAs and the suggestion for their further rationalization. The panel discussion was very useful and enjoyed by all the participants. The workshop was planned mainly to spread more awareness and information amongst the power utilities, industry, regulatory and planning authorities and the academic and research institutions about the specific issues being faced by power sector in respect of grid security and management and the action plan to address the same. These were deliberated in detail in the workshop and a definite message and information could be spread amongst the wider section of people about the prevailing issues and action plans to address the same. In the panel discussion also the specific issues on the subject matter were deliberated and addressed by the authorities in the respective fields.
