• Preparing for the future of grid-code

    Apr 2020 / by DIANE CLIFFORD and ANNIKA BÖHM

    As growth in distributed energy and other factors increase the risk of instability on electric utility systems, nations and grid providers are tightening grid-code requirements. Developers of distributed energy projects need to stay current with grid-codes and can look to a trusted equipment manufacturer for help with compliance.

    Improvements, new innovations and status of solar thermal power plants in India

    Apr 2020 / by SRINIVAS GUGULOTHU and M. RAVI KUMAR

    A high solar radiation available in India is a factor to encourage the full development of solar power plants for thermal and electrical energy productions. Most parts of India, Asia experience a clear sunny weather for about 250 to 300 days a year, because of its location in the equatorial sun belt of the earth, receiving fairly large amount of radiation as compared to many parts of the world especially Japan, Europe and the US where development and deployment of solar technologies is maximum. Photovoltaic (PV) and solar thermal technologies are two main ways of generating energy from the sun, which is considered the inexhaustible source of energy. PV converts sunlight directly into electricity whereas in solar thermal technology, heat from the sun’s rays is concentrated to heat a fluid, whose steam powers a generator that produces electricity. Solar thermal technology is more pollution free energy than solar photovoltaic energy.

    In this paper, a brief description and working principles of the solar thermal technology are studied. Besides, the paper points out the solar energy potential, the current state of electricity generation and the future of solar thermal power projects in the country. Special attention is drawn to the Indian government initiatives and support for the use of solar energy. In the end, the future prospects of solar projects development with the worldwide competitive technologies by considering the existing obstacles that should be removed by the Indian governments and energy planners in the future of energy production are presented.

    Keywords: Solar thermal power plant, solar thermal energy storage, concentrating solar power, heat transfer fluid (HTF), thermal energy storage (TES), phase change material (PCM).

    Prospects of offshore wind power generation in India

    Apr 2020 / by SARAVANAN, M. ARAVINDAN, V. BALAJI and M. ARUMUGAM

    To mitigate the global climate change and to enhance India’s renewable power generation capacity and to deploy low carbon energy production with improved energy efficiency, offshore wind generation is being suggested in this paper. Policy and regulatory framework aspects for achieving 5 GW offshore wind installations in the states of Gujarat and Tamil Nadu by the year 2032 with current practices and sophisticated technologies adopted throughout the world is presented. For effective implementation, suitable measures and actions to be taken by various stake holders are also mentioned.
    Keywords: Offshore wind power, policy and regulatory framework, wind power generators, AC-DC power converters, HVDC transmission, offshore substation, power quality/stability studies, wind farms
