Efficient utilization of renewable energy sources (RES) is one of the major concern in present power sector scenario which can satisfy the energy requirements of an area in proper and sustainable manner. The efficient utilization of RES helps to reduce the total cost of energy generation. The main objective of the present work is to examine the efficient utilization of different modes of RES like...
The System Operator (SO) is an authority responsible for the secure operation of the power system and in this way, the SO has to obtain or procure some services that maintain a balance between generation and demand in any electricity market environment. These services are termed as an Ancillary Services (AS). Therefore the management of all these services are considered as a specific function of the...
Inderegulated environment, Ancillary Services (AS) plays a vital role, as they are required for reliable and secure operation of the power system. Operating Reserve (OR), as one of the main AS, is a capability of a power system to prevent any unexpected imbalances caused by generation or transmission outage has been considered in this work. This paper considers a flexible disaggregated energy and...
Ester based dielectric liquids with attractive environmental and temperature performance draw the attention for those interested in alternate dielectric liquids for transformers. In this paper Breakdown voltage and Spectroscopy analysis of Mineral Oil, Natural Ester and Synthetic Ester and mixture of mineral oil with Synthetic ester has been compared for fresh samples. Trending patterns of these samples...
Ester based dielectric fluids were found to beat mineral oils in thermal and environmental aspects. Hence there is a great need of research on ester oils. The present paper is a review of 84 published articles. Owing to length of the document; exceptions were made to include a citation if a publication contributed a significantly technical viewpoint on usage of ester oils for transformer insulation...
This paper present the degradation characteristics of transformer oil. Degradation accelerates in the presence of moisture and high temperature. So it is important to investigate dominant factors of transformer oil. Sample of four working transformer of 50 to 150 MVA and voltage class 400/220Kv is taken for the test. In this paper investigation is done with the help of graph and shows the characteristics...
This paper proposes a generalized model of the photovoltaic cell in Matlab-Simulink. This proposed model is based on basic mathematical equation of solar photovoltaic cell. The PV modules have non-linear output characteristics. The output I-V and P-V characteristics of photovoltaic cell are depend on sunlight irradiance and cell temperature. The model can be used to extract the physical parameters...
This Restructuring and deregulation of the electricity industry is a movement with the aim of achieving lower prices to customers through cost savings. The deregulation of electric power systems in many parts of the world has changed the mechanism of electricity pricing. India is in the processing on restructuring in power sector. Power planning will play an important role in the successful power...
Renewable energy is a sustainable and clean source of energy derived from nature. These technologies have long been recognized as an important part of the solution to address energy security concerns and ensure economic growth in an environment friendly manner. Deregulation has changed the traditional mission and mandates of power utilities in complex ways, and had large impacts on environmental,...
The World is gradually shifting focus toward its renewable energy resource. Driven by an increasing demand for electricity and widening gap between demand and supply. World has target 800 GW of Renewable power by 2035, Without including Small Hydro power plant and has been enduring a pressing need to reduce its high and increasing greenhouse gas emission. Renewable Energy in the world day by day increases...
Renewable energy sources and technologies have potential to provide solutions to the longstanding energy problems being faced by the developing countries like India. Solar energy can be an important part of India's plan not only to add new capacity but also to increase energy security, address environmental concerns, and lead the massive market for renewable energy. Restructuring has changed the traditional...
The power industry is moving rapidly from regulated conventional setups to a deregulated envirorment. There is an urgent need to keep a track of intemational experiences and activities taking place in this emerging field. This paper gives a bibliographical survey and general background of research and development in the field of power system wheeling under a deregulated environment based on over 170...
