Indian distribution sector is constantly facing energy crises. With the increasing dependency on electrical and electronics appliances the demand of power is rapidly increasing. Extensive work is going on to increase the generation capacity by encouraging renewable energy integration for generation diversification, energy conservation and regulations, development of open access energy markets etc. but simultaneously it is also important to optimally use the existing generation capacity. Electricity theft and meter tampering is one of the most important causes of increasing gap in demand and supply and poor financial condition of distribution sector in the country. Unaccounted energy due to theft is a barrier in the growth of Indian economy. With the advancements in metering technologies different new ideas of illegal electricity theft are also being introduced by consumers. This scenario is very challenging for the profitable operation of distribution sector and putting them in loss. In this paper we have discussed meter tampering and theft issues and their drawbacks. Smart meter can work as the best solution to control theft events due of its features of remote data communication and connect /disconnect ability.

In spite of India holding the second position in production of fruits and vegetables in the world, about one third of these are wasted in post-harvest. Major chunk of post-harvest losses are attributed to lack of proper cold storage and cold chain facilities. The quality and life of the commodities are determined by their storage conditions. Hence, designing an intelligent cold storage system turns out to be very much essential in order to mitigate the post-harvest wastage of the perishable commodities. This enables remunerative prices to the cultivators in addition to making the commodities available at competitive and affordable prices to the consumers. Based on the technical standards for control atmosphere cold stores temperature, humidity, CO2 level and light intensity level are the essential parameters to be monitored and controlled for maintaining their quality and life. However, currently available cold storage systems in India do not consider controlling of all these essential parameters. With an intention to address this, a wireless sensor network based fuzzy logic controller for monitoring and controlling these essential parameters is proposed here.

The placement of shunt capacitor banks at optimal locations in the distribution network and their sizing can effectively reduce the losses in the utility network. It also helps in the maximum active power flow through the existing distribution lines which. This also increases the power transfer capacity of feeders and improves the voltage profile of the feeders which leads to reduced investment of transmission network. This paper presents a method for optimal placement and sizing of the capacitors in radial distribution feeder using Genetic algorithm (GA) with an objective of loss reduction and voltage profile improvement. The results have been validated using MATLAB programming. An IEEE 33-bus distribution test feeder is employed for testing the proposed algorithm. The optimal sizing of the capacitors has been suggested in terms of the kVAr.

Increasing level of environmental pollution, petroleum prices and depleting level of natural resources are major troubles caused by internal combustion engine based transportation system. Hybrid electric vehicles (HEVs) have presented the solution to these problems and are assumed to be future green and sustainable transport medium. HEVs utilizes engine and battery together to give power to the wheels. Since, presence of two sources causes the complexity at architectural level of vehicle, hence requires a judicious power split between them. To split power efficiently between engine and battery, an intelligent energy management scheme is required to be implemented. An efficient power split scheme may consequence in better fuel economy and performance of HEVs. Here, particle swarm optimization based intelligent energy management scheme is implemented and compared with genetic algorithm and dividing rectangle algorithms. Modified state of charge (SOC) estimation method and 1RC battery model are used for simulation purposes in advanced vehicle simulator (ADVISOR).

This paper proposes a standalone double stage solar photovoltaic (PV) water pumping system. This system utilizes a PV array, boost dc-dc converter, three phase VSI (Voltage Source Inverter), PMSM (Permanent Magnet Synchronous Motor) and a centrifugal pump. The boost converter used between PV array and VSI, serves the purpose of MPP (Maximum Power Point) tracking by adjusting the duty ratio using an INC (Incremental Conductance) method in order to extract optimum power from the PV array. The PMSM is driven in vector control mode which drives the pump. A power feed-forward term is utilized which improves the system dynamic response. In this way, the purpose of effective and efficient water pumping is accomplished. The proposed system is modelled using MATLAB/Simulink environment and its performance is simulated to study its behavior under varying insolation levels.

The higher shares of distributed generation (DG) sources lead to unpredictable rise in voltage level due to intermittent and stochastic characteristics of DGs. This paper intends to report the online Volt/Var control in a smart grid with multiple DG systems. The objective of Volt/Var control is to recover the network voltages within the admissible limits by coordinating the operation of the DG and the OLTC transformer. Firstly, voltage profile of the system is estimated by remote terminal units (RTUs) placed only at DG node. Next, a direct voltage sensitivity based method is developed to choose best DG for reactive power injection in multiple DG environments. Finally, OLTC transformer is employed in voltage regulation process when DGs reactive power is insufficient for maintaining the voltages within predefined limits. The reported method tested on 12-bus radial distribution network to validate the theory. The reported simulation results show that the presented method effectively maintains network voltages within admissible limits.

This paper presents a strategy for the energy management for a hybrid PV/Wind/Battery (PWB) energy system using the adaptive network-based fuzzy inference system (ANFIS). The energy management system is aimed at reducing the fluctuations of power injected into the grid, which is one of the major problems in the renewable energy systems. Another objective is to maintain the battery state of charge (SOC) within the acceptable limits so that the lifetime of the batteries can be increased. The ANFIS has been used to manage the power among the grid, source and the batteries. The results demonstrate that the ANFIS is rendering good performance and the fluctuations are reduced considerably.

Increase of load and demand factor on power grids has made supply of electric power to rural areas as a big challenge. The idea of increasing the number of power plants could not be much efficient because it increases the emission of carbon and production cost. Hence use of renewable power sources seems to be much more efficient. The main motive of this proposed work is an efficient design of solar panel for constant Current-Voltage (V-I) characteristics of a Photovoltaic array of various environmental conditions like different irradiance and temperature. A proposed model uses constant environmental condition in combination with actual solar radiation and ambient temperature. The new design is developed on Mat lab-Simulink platform for calculating and analyzing the power output from a PV panel by taking the values of current and voltage with constantly varying solar radiation at any geographical location and different day The output power of solar panel is directly given to dc /dc controller in order to reduce circuit complexity. The estimation of MPP (maximum power point) of a Photovoltaic (PV) array is done by calculating the value of both ampere, voltage and power curves for changing environmental conditions.

DC-Link Capacitors are one of the core constituents in many power electronic systems mainly DC-micro grids. They contribute significantly to the overall size. In this paper, a technique “Stacked Switched Capacitor” (SSC) proposed earlier is modified by using an array of electrolytic capacitors and switches as an alternative to a large electrolytic capacitor. The new topology is named “electrolytic SSC” (eSSC) and it effectively reduces the size of the converter. This technique replaces a large electrolytic capacitor with smaller capacitors and an array of switches to mimic the behavior of a large electrolytic capacitor. In this paper, the proposed topology is analyzed and different design requirements are taken into account for the proper functioning of the eSSC. The simulation results are presented and an estimate of the relative volume of the original SSC shows that the proposed eSSC indeed reduces the size by a reasonable amount and it can be inculcated into any system where capacitor bank is required which draws current at line frequency.
