The proverb “Health is Wealth” means a healthy man is rich. We live in a society that values high quantity and low quality of food. This is where pesticides playa significant role. They increase yields and the number of times a particular crop can be grown on the same land. Pesticides are potentially toxic to humans and can have chronic health effects, depending on the quantity and ways in which a person is exposed. The use of pesticides to produce food should comply with good agricultural practices. Farmers should limit the amount of pesticide used to the minimum necessary to protect their crops. Here in this paper, a method to protect the crops and an E-Farmers market has been developed. The amount of pesticides used on a particular crop determines the pesticide content with which the fruits or vegetables have been grown. The solution described in this paper determines the pesticide level by measuring the pH of the soil which varies with an increase in the use of pesticides. This measured value is updated in the E-Farmers app through the cloud and is compared with a pre-loaded value which is the minimum value of pesticide requirement for a particular crop. Based on the result obtained it displays if the product is fit for consumption or not. This will also help to eliminate the third-party dealers as it establishes communication between the farmers and the customers.

Presently, vehicle to grid (V2G) technology has gotten a lot of recognition, because a big number of electric vehicles are progressively getting into the market. The electric vehicles (EV) which are plug-in electric vehicles that may act either as a source or as a particular electric load and these can be utilized as a storage device on the go to help with load balancing in the grid and to allow the opportunity for the non-conventional energy source integration. The vehicle which is proficient for V2G offers the support of reactive power, regulation of active power, stability, and reliability. The V2G is capable of unidirectional or bidirectional power flow. This technology includes the DC-DC bidirectional converter and AC-DC bidirectional converter which will share the common DC bus. The V2G technology implementation in the power grid will face many challenges and can be avoided by implementing it in the micro-grid. The battery technology, bidirectional charger, and power flow from V2G and G2V are discussed in this review.

This manuscript introduces a control scheme for grid interactive photovoltaic inverter system. For designing a control system for grid interfaced converters voltage and current sensors are required. The control strategy introduced does not uses a voltage sensor for measuring the grid voltage thereby reducing the sensor count. Reducing the number of sensor is more economical as it reduces the overall cost and increases energy efficiency and also the system reliability. A sinusoidal signal integrator is used for generating the reference voltage signal for grid voltage estimation unit. A proportional + resonant controller is designed to dictate the output current of the grid interfaced inverter. The objective of the current controller is to regulate the power flow between the photovoltaic source and the grid and to make the output current injected into the grid harmonic free. The control scheme introduced is assessed under a variety of operating scenarios to which it can be subjected when the solar inverter is working on a grid interfaced mode. The simulation results confirm that the control scheme estimates the voltage under all operating conditions and the proportional resonant current controller demonstrated excellent response by mitigating the injected current harmonics and enhancing the power quality.

The grid connected Photovoltaic (PV) systems have attracted significant attention in the recent years, thus, the reliability of grid-connected inverters has become a major concern. Any kind of failure at the inverter side may severely affect the output power leading to instability at the grid end. To improve the system availability and reliability, an inverter fault diagnostic mechanism becomes imperative. This paper proposes novel Support Vector Data Description (SVDD)-based fault detection technique for grid connected single-phase PV Inverters. It possesses the ability to address the problem of anomaly detection. It seeks to find the hypersphere with minimum volume containing most of the relevant fault-free data objects. With the occurrence of fault, the faulty data points will be the outside of the hypersphere. The fault detection and classification algorithm is developed in MATLAB/Simulink environment. The simulation results verify the effectiveness of the proposed technique.

This paper examines the effects of parasitic capacitances of the high-frequency transformer on matrix converter based solid-state transformer (SST) operation. SSTs involve high frequency transformers for isolation. With the increasing trend towards high-frequency operation to achieve higher power densities, the parasitic capacitances of the transformer become prominent. The inclusion of these capacitances modifies the equivalent circuit of the transformer. The current research does not take into account this modification. It is essential to identify the effects of this modified equivalent circuit on the operation of SST for better predictability and reliability. This paper also quantifies experimentally the parasitic ca-pacitances associated with the high-frequency nanocrystalline transformer. The effect of these parasitic capacitances is observed on the transformer input current and output voltage. These system quantities are essential for pulse width modulation of the matrix converter-based SST. A comprehensive examination of these effects is performed which includes the variation of other involved circuit parameters along with parasitic capacitances such as transformer leakage inductance, resistance, connecting wire inductance and resistance. This examination also lends useful insights into high-frequency transformer design for SSTs. The analysis can also be applied to SST topologies which involve high frequency transformer and similar voltage and current waveforms.

Induction motor (IM) drive with open ended stator windings achieves multilevel inversion as an integral part of the load. The open ended configuration is fed with two 2-level voltage source inverters on both sides. The 3-level multilevel inversion with open-ended configuration is achieved by maintaining equal DC-link voltages on both sides of the inverters. The advanced control strategy like predictive torque control (PTC) technique with PI controller was suggested in the literature to regulate the motor speed and to improve the open-end winding IM (OEW-IM) drive performance. In case of conventional PI-controller, the PI parameter tuning is needed. This paper presents a fuzzy-logic speed controller (FLSC) for 3-level OEW-IM drive with PTC technique. The FLSC is used to control the speed of OEW-IM. The simulation results are carried out on a 4-kW OEW-IM. The simulation results reveals that, the FLSC improves the drive performance when compared to the PI-controller.

Traditional power is reliant on fossil fuels, which are slowly depleting and causing environmental concerns. As a result, energy dependency has gradually moved towards renewable distributed generation (DG) resources in the current power distribution system. With the more penetration of DGs, protection of hybrid microgrid network is becoming increasingly complex. In this work, a protection scheme is developed for hybrid microgrid with Discrete wavelet transform (DWT) and Ensemble of k-nearest neighbor (kNN) to perform the dual task of fault detection and faulty line identification. Testing of the proposed scheme has been performed against various internal and external fault scenarios. In terms of accuracy, the proposed scheme outperforms single kNN and linear support vector machine (SVM) classifiers.

For low voltage power generation applications, this paper projects an inimitable high-gain DC-DC converter topology. The proposed topology employs a switched capacitor circuit, H-bridge inverter, boost circuit with anti-series switches and voltage doubler for obtaining the high voltage gain. The proposed topology uses nine switches, one switched capacitor, coupled inductor, voltage doubler circuit for producing high-gain in the output voltage. To achieve high-gain at the output, the proposed converter operates discontinuous conduction mode. For the 50 percent duty cycle of the boost switches, the proposed converter produces a gain of about 25 times. The proposed converter can give output for a wide range of input DC bus voltage. The operation of proposed high-gain DC-DC converter is verified using PSIM software. The paper describes the operation of the proposed high-gain DC-DC converter, including its modes of operation and simulation results.

This paper presents a cascaded five-level inverter which minimize the magnitude of leakage current flowing through the parasitic capacitance of the PV panel. The topology generates the five levels in the inverter output voltage with the help of two switched capacitors. The magnitude of voltage across the switched capacitors decides the modes of operation of the cascaded five-level inverter. The five-level topology can be operated in two modes: buck mode and boost mode. In the buck mode, the maximum value of the inverter output voltage is equal to the DC bus voltage. Whereas in the boost mode, the magnitude of inverter output voltage is equal to twice the DC bus voltage. Apart from the five-level generation, the inverter topology also maintains constant commonmode voltage (CMV) for both the modes of operation. As a result, the magnitude of commonmode current is also minimized. Complete details regarding the operation of five-level inverter, simulation results are presented in the paper.

This paper presents a simulation of a hybrid AC-DC microgrid on the MATLAB/Simulink platform. Each side of the microgrid has one PV generator, while the dc side has a BESS connected. Simulations are done for islanded and grid-supported modes of the microgrid, and the importance of BESS in providing stable voltage in an islanded microgrid is highlighted. A scheme is proposed that employs BESS to limit sudden change in power flow through the main converter due to switching dc loads in grid-supported mode. The scheme requires BESS to inject/absorb power into/from the dc bus as calculated from voltage imbalance in dc side.
