As a part of prosumer concept, reactive power supply using the end user equipment is evolving. Reactive power injection using end user appliances is used for voltage profile correction, reduction in losses and improvement in power factor. In a radial distribution network, when there are reactive power supplying devices available at different locations, selection of reactive power source will have...
In the fast evolving world of information age, the value of open data is being recognized around the world. The information and communication technologies are making it easier to collect and store data. The consequent use of this data is leading to smartness in the respective sectors. Since power infrastructure is critical for national security, the availability and access to data is one of the hurdle...

Shift of the focus from bulk generation to distributed generation is an established global trend in the power sector. Further the mode of distributed generations is shifting from dependence on fossil fuels to renewable sources. These sources are intermittent in nature and their generation pattern does not match the load pattern there by creating a need for a battery storage system. In this context,...
Power distribution transformer is one of the key asset to be managed by the utility. Ageing of transformers causes operational and financial burden on the utility. Excessive temperature is the primary cause of ageing of the transformer. Traditionally, utilities resort to load shedding in-order to save the transformer during high temperature periods. Instead, the concept of demand response can be used...
The conventional large power network diagram creation and editing is time-consuming and requires considerable effort. A method for automatic generation of the power network layout given the connectivity and initial co-ordinates of buses is described in this paper. In this method, force directed graph layout algorithm is used, which improves the layout by re-organizing the buses to eliminate crossings...
Conventional power system graphic applications use absolute coordinates approach, in which the objects are positioned with respect to a common origin. This can result in problems of re-adjustment and re-alignment in the network and substation diagrams when editing or merging the graphics. This paper introduces the notion of layouts and proposes a graphics model to facilitate positioning of graphical...
