The application of DC microgrid is increasing due to the elevation of renewable energy (especially solar energy) practice. Increasing reliance on the DC microgrid seeks more reliable or faultless operation for impeccable control over the DC grids. The concept of reliability enhancement is at its verge since none of the electronic devices can be operated forever. Therefore, the idea of fault tolerance in the presence of redundancy has emerged. This paper proposes the review on fault phenomenon and reliability of the power electronics converters from various aspects such as performance, application, efficiency, etc. Different fault-tolerant schemes reported in the literature have been critically reviewed, compared, and explained in detail to have insight into the prominent solutions. This paper aims a bridge between the inference of reliable and fault-tolerant ability of power electronic converters for DC microgrid`s application. The ability to diagnose and intimate such faults in real-time has also been discussed in addition to various fault-tolerant converter topologies.

The increase in power demand has given rise to invest in renewable energy sources which are much better than conventional sources of power. But the renewable power sources such as wind, PV are variable in nature which affects the power quality of grid. Hence, the power system is required to make balance between power demand and generation. In order to improve the stability the PID controllers are used. But these are fixed gain controllers. So, to overcome this issue, AI techniques must be used. This paper presents the hybrid renewable energy system with wind, PV and Fuel cell connected to the grid. The PID controller is employed with the system whose parameters are tuned with Particle Swarm Optimization technique. This optimization improves the stability of the system. The modeling and simulations are done in MATLAB and results are observed for better performance under variable loading conditions.

Use of Versoria as a cost function for adaptive filtering is a recent method in signal processing. By maximizing the generalized Versoria function, the steady state misalignment can be eliminated and computational efforts can also be reduced. The paper proposes use of maximum Versoria criteria (MVC) for evaluation of active and reactive power component of load current, for generating the reference signals for DSTATCOM for power quality intensification of the power grid. MVC algorithm also shows robustness against impulsive noises present in the power grid. The paper shows the implementation of MVC control algorithm for DSTATCOM to elimination the harmonics, reactive power compensation and load balancing. The algorithm shows satisfactory performance for the control of DSTATCOM.

This paper presents the planning of a grid-connected microgrid model and analyzes its economics using HOMER Pro software. A case study at the location of Thapar Institute of Engineering and Technology (TIET), Patiala (Punjab) in India considering grid-connected PV and battery storage systems has been presented in this work. The analysis of the result shows the impact of a grid-connected PV system with battery backup on the overall cost of energy. Also, the role of solar irradiance on the overall output of the PV source has been highlighted by comparing the cost of energy while considering the global horizontal irradiance (GHI). The result shows that the cost of energy varies in an inverse manner with the variation in GHI. This paper shows important aspects in the planning of microgrid on the basis of the location of DERs, resource availability, load profile of consumers, cost of energy, the capacity of DERs including its capital and maintenance cost.

In this paper a line voltage sensorless predictive Direct Power Control (DPC) technique for three-phase Active Front End (AFE) rectifiers without inner loop PI controllers and Phase locked loop (PLL) is presented. The proposed predictive power control technique is based on the Virtual Flux (VF) concept and direct power control philosophy. The introduced technique has combined features of predictive technique for better response as well as a virtual flux concept as an inherent filtering. Therefore, it improves reference voltage generation which is further utilized by Space Vector PWM (SVPWM) technique for generation of the pulses. In this manner, the estimation of reference voltages from the proposed approach reduces the power errors, power ripples and Total Harmonic Distortion (THD) in line current. SVPWM provides the constant switching frequency therefore EMI filter designed is easier. In the proposed approach no PI controllers in inner control loop is required, therefore it does not need any tuning effort. Also, the sampling frequency requirement for the proposed technique is lesser to follow the IEEE standard-519. The experimental laboratory results demonstrate that the introduced technique provides independent control of real and reactive powers with better power quality performance than the existing VF table based DPC.

In the Energy management System (EMS), economic dispatch is an important issue. Economic dispatch optimizes the per unit cost of generation. The economic operation of thermal plants with wind integration is proposed in this paper. Dynamic economic dispatch (DED) problem has been solved using quadratic constrained programming by CPLEX solver in General Algebraic Modelling System (GAMS) software. The effect of wind integration has been studied on the economic operation of thermal units considering first test system. First Test system consists of three thermal units and second test system consists of six thermal units. A day ahead wind forecasting and demand forecasting have been considered for analysis. Finally first test system with wind integration for a day ahead has been taken to illustrate the effectiveness of proposed method to solve DED with wind integration.

Use of distribution generation (DG) system in large scale is becoming an encouraging scenario for electric power generation. For this purpose, three-phase voltage source inverter (VSI) carried out a major role to link between DG and grid. The inverter must be operated smoothly and stay connected during voltage sag or any kind of disturbances takes place. Till date, several control strategies have been invented and also implemented in different systems globally to maintain the healthy operation of the inverter. This paper proposes an alternative method to control the voltage source inverter of grid-connected solar photovoltaic (SPV) system. The proposed work is focused on an alternative inverter control process based on a synchronously reference frame phase-locked loop (SRF-PLL). A modified dual-loop feedback control strategy has been introduced and implemented in the proposed system to show effective control of a three-phase grid-connected voltage source inverter. All the simulations have been carried out and verified in MATLAB/SIMULINK environment.

Evolution of Phasor Measurement Units (PMU) improves the power system estimator’s performance. PMUs are widely use in transmission systems and by considering its contribution there, it is expected that in future it will be used in distribution networks. First and foremost step towards implementation of micro-PMUs in distribution system is to determine optimal location of µPMUs. Since PMUs are generally used in transmission systems so mostly algorithms related to optimal placement (OPP) are not considered the radial structure of distribution network. In this piece of work, Traditional Depth Search Algorithm and a Proposed Modified Depth Search Algorithm are adopted to solve judicious µPMU placement problem. Proposed Methods are tested on 40 and 85 IEEE radial distribution feeder, randomly integrated with distributed energy resources. Results obtained indicated that proposed algorithm overcomes the drawback of depth first search algorithm of not providing optimal solution.

High penetration of renewable energy could lead to minimizing the greenhouse gas emissions and petroleum dependency of a country. To achieve this, an optimized renewable energy integration model is required. Hybrid Renewable Energy System (HRES) is an integrated model of renewable energy generation and the load. Therefore, this model will depend on the renewable energy resource availability of a concerned geographical area and its local demand. There are many models to integrate renewable energy into an electrical grid. Among them islanded models without a grid connection are developed in rural areas due to their self-contained nature. These hybrid renewable energy systems usually have solar and wind energy as their primary energy source where a diesel generator is used as the backup supply. To integrate renewable energy, the integration model should be precisely designed. This paper discusses the renewable energy integration models in-depth from the view of distributed generation and micro grids. Different hybrid renewable energy systems were compared and assessed to evaluate their inadequacies and limitations. Future challenges and remaining issues are also discussed.
