With more than 21,000 MW installed capacity of renewable energy sources as of now out of an estimated potential of about 189,000 MW, in the years to come it is really a challenge to integrate the same into the smart grids in a country like India. This is basically on account of unevenly distributed renewable resources. With 5 regional grids gradually getting connected, formation of national grid in totality is a reality. Of course with major sources of generation being thermal with availability up to certain distant future, entire thrust has been put in recent years on the development of renewable resources that would be the source of energy to run side by side to the conventional ones. At the same time vast assets created in transmission and distribution will also continue to be gainfully used, may be in conjunction other form of value addition to the same for proper functioning. Under this condition, keeping in mind the eventualities, regulations have been framed and so also the certification process has been made effective to handle the situation particularly on grid connectivity front. Expectations from smart grids by the consumers and suppliers as well of course may lead further refinement to the existing protocols in the process in the years to come as and when harnessing of renewable resources progresses to attain a very high level. © 2012 IEEE.

The Renewable Energy Certificate (REC) Mechanism has proved to be quite successful across the globe and is prevalent in many countries including the U.S., the U.K., Japan, Australia, etc. It is expected to play similar role in promoting the renewable energy technologies in India. India has launched its REC Mechanism in November 2010. It is a pan India market based instrument and has been introduced to meet 'Renewable Purchase Obligation (RPO)' and 'Voluntary' purchase of the RECs. REC Mechanism provides two different markets to the RE Generators - one from sale the electricity component as 'conventional electricity' and the other for the associated environmental attributes in the form of REC(s) and expected to bring about a paradigm shift for the renewable based electricity in future. The REC framework has been established and about 3400 MW capacity has been registered under the Mechanism. In March 2011, in the first trading session for RECs, the issuance of RECs was just 532. In February 2013, the twenty fourth trading session was held which witnessed the issuance of RECs crossing the 5 millionth mark. Though the RECs continue to hold promise, the market's performance has been weak in recent months. This paper presents a brief overview in terms of the concept, salient features, status, trends, issues and the way forward in the Indian Renewable Energy Certificate(s) Mechanism. Source

With smart grid typically characterized by attributes like, reliable and secure, efficient and economic, environment friendly and safe to the extreme extent as feasible, it calls for quality transmission and distribution operation backed by generation with optimum utilization of assets considering expected level of commitment from all stakeholders. Latter encompass investors, owners, traders, service providers, operators, and consumers of different categories. Such being the concept plant operation and control assumes an important, but difficult task at every instant of time to go. With Indian grid still growing to meet demand along with expansion of network whether from new generation or strengthening intermediate power systems, stabilization of the process would definitely take some more years. But aspiration of consumers nevertheless is not going to stop from the point of view of quality, besides quantitative adequacy at every instant of time. This calls for on the one hand smart grid to adjust with generation and its possible storage with availability whenever and wherever called for, self-healing mechanism in the face of disturbance, optimum utilization of assets achieving high level of efficiency in operation, while at the other hand consumer getting quality electricity as per quantitative requirement, through successfully enabled provision of services, products marketed, etc. Extensive usage of digital technology in terms of communication and information technology on real-time basis is an essential feature for achieving success in the matter considering the demand-supply scenario accurately at every instant. Depending upon the same means of automatic or intelligent operation and control within smart grid concept has been deliberated in the paper. © 2011 IEEE. Source

The Indian electricity grid is among one of the largest power grids in the world, with an installed generating capacity of 259 GW as of February 2015. The Indian power sector started its consolidation and expansion in early 1990 with the establishment of a central utility, Power Grid Corporation of India Ltd. (PGCIL). India's power system is managed by the five regional load dispatch centers (RLDCs), one for each regional power system. The implementation of supervisory control and data acquisition (SCADA) and energy management systems (EMSs) took place from 2002 to 2006. The national load dispatch center (NLDC), which coordinates operations of the five RLDCs, started operations in 2009. Interconnections among the five Indian regional grids started in the early 1990s, and all regional grids have been synchronized since 31 December 2013. Currently, the five RLDCs and the NLDC are managed by the Power System Operation Corporation (POSOCO), a subsidiary of PGCIL. The Indian grid has been able to maintain a reasonable degree of stability over the years, despite the exponential expansion of loads and renewables integration. © 2015 IEEE. Source

In India there are close to forty (40) Load Despatch Centres (control centres) for power system and electricity market operation. In order to assess capabilities of these Load Despatch Centres (LDCs), a nationwide survey was conducted with the help of a questionnaire. This paper draws inferences from the findings of the survey. It emphasizes that institutional capacity building of the LDCs in India is highly relevant in view of the ongoing reforms and restructuring, increasing vulnerabilities of the interconnected grid, rapid growth in the interconnection size, generation capacity addition, equipment/human failure, cyber attacks, environmental threats and fast changing regulatory framework in India. The paper argues that the effective coordination amongst the system operators can come by establishing functional and financial autonomy of the LDCs as well as by strengthening the capabilities of the human resource working in the LDC. The paper provides an overview of the recent initiatives being taken by the policy makers, regulators and the utilities in India for institutional capacity building of the LDCs. Most significant amongst these are the recommendations of the committee constituted by the Union Ministry of Power (MoP), Government of India (GoI) on manpower, certification, and incentives for system operation and ring fencing of LDCs; the report of the various task forces set up by the MoP for implementation of the recommendation of the committee; the Regulations on fees and charges of the LDCs notified by the Electricity Regulatory Commission; the formation of Forum of Load Despatchers (FOLD); the creation of ISO structure for operation of the National and Regional LDCs; and the programme for training and certification of power system operators in India being undertaken. The paper opines that the recent initiatives are significant as they would help in improving the awareness of the overall status of the interconnected power system in India and coordination amongst the System Operators. It argues that institutional capacity building of the LDCs in India would be instrumental in synergizing the benefits of the various reform initiatives in the sector. The paper also highlights the various issues being faced in the implementation of the various initiatives and provides a future outlook. Source
