Abstract: This paper targeted to reduce the Queue at a billing counter in a shopping complex. The system does the same by displaying the price of the product inside the cart. In this way the customer can directly pay the amount at the billing counter and leave with the commodities he/she has bought. It eliminates the traditional scanning of products at the counter and in turn speeds up the entire process of shopping, also with this system the customer shall know the total amount to be paid and hence can accordingly plan his shopping by only buying the essential commodities resulting in enhanced savings. Since the entire process of billing is automated it reduces the possibility of human error substantially. Also the system has a feature to delete the scanned products to further optimize the shopping experience of the customer. The hardware for the test run is based on the Arduino platform and zigbee modules, as both are very popular in small-scale research and wireless automation solution. Also the amount can be paid through online using QR code scanner.

Authors: Ravindran, N.; Kokulavasan, T.; Rajan, R.; Yuvaraj, M.; Ahilan, K.; Atputharajah, A. Abstract: Continuous supply of electricity, when there are supply constrains is a mar challenge. Environmental concerns and nonavailability of fossil fuels increases the demand for the use of renewable energy sources such as solar. A domestic or an institutional customer can support the country by the proper usage of solar Resources. Further the usage of a battery storage combined with the solar panel can improve this. This paper analyses the domestic institutional usage of solar panels, (i) with and (ii) without a battery storage, for both cases of (i) with grid and (ii) standalone operation, depends on the availability of solar irradiation in a day. Here a typical domesticnstitutional solar power system tan into the study and suitable sizes of solar panel, battery storage were selected to achieve a reliable and smooth operation of the system. The whole system is modeled using PSCAD simulation. The design of the controllers ensured the proper operations of grid connected and standalone mode of the system. Further MPPT control also used in such a way to ensure the optimum usage of solar power. The simulation results shows that this arrangement improves the power availability for domestic institutional customers even during the power failure periods.

Abstract: Many research papers discussed the increasing fossil fuel cost. As the cost is increasing in the present scenario it is necessary to incorporate Renewable Energy (RE) technologies to take primary role in generating electricity. As a result of increasing the RE – based power generation and reducing the fossil fuel technologies to generate electric power has created real challenges in power system operations. It is the high time for the researchers to do detailed analysis to find possible ways to tackle the challenges in power system operations. In the past, power system preferred to have large inertia to keep up its operations especially during transient periods of a disturbance. The modernized systems with latest technologies and their speedy responses, could create inertia by properly coordinating the control of many, small, generating plants. Further the accurate prediction algorithms release the stress by giving advance information about the system. As it is a new direction of modernized control, it always starts with small system and then integrates with large system through a supervisory control loop. This is opening a new direction with the RE technologies to be incorporated through microgrid systems.
