Broadband Power Line Communications (BPLC) meritoriously uses the existing power line system as a high speed data communication medium. the power line was initially considered to allocate electrical power in an effective way. Electrical wiring was never intended to serve as a communication medium as it presents a number of unfavourable characteristics; such as varying impedance, signal attenuation, and noise. This paper presents the modeling and analysis for different topologies of the powerline channel of the indoor network using MATLAB software. Also, getting the analytical expressions of the transfer function for the power line channel, to explore the validity of the channel transfer function. We also presented, the impact of peak to average power ratio (PAPR) on the BPLC system by clipping and filtering method on the Orthogonal Frequency Division Multiplexing (OFDM) signal.

The paper proposes a dual output DC-DC converter for electric vehicle battery charging application from the PV source. The proposed converter is derived from modified SEPIC Converter (converter-A) and multilevel boost converter (converter-B) in such way that both converter share common input source as PV. Generally, the voltage of PV is low and series and parallel combination of PV module is not a practicable solution to accomplish high voltage demand of electric vehicle charging station. Therefore, the high gain DC-DC plays a vital in PV integrated electric vehicle charging station from low to high voltage conversion. However, with dual output capability and single switch controlled structure make the proposed converter a superior choice for PV integrated EV charging station. In addition, the same or different rated output can be achieved with proper selection of duty ratio. The working principle with characteristics waveform and mathematical analysis of voltage gain are discussed in detail. The proposed converter is simulated in MatLab 2018a and obtained simulation result proves the mathematical analysis and functionality of the converter.

During recent past, DC natured electrical networks such as a DC micro-grid have received significant attention over their conventional AC driven counterparts. An increasing interest in the renewable, clean, and sustainable power generating sources, natively DC energy storage, and semi-conductor technological advancements led large number of DC equipment are behind this ever-increasing interest in the DC natured electrical networks. Interfacing seems necessary in an electrical network to establish the compatibility between different possible voltage levels available at the generation, energy storage, and loads. Multiport DC-DC converter (MPC) based interfacing is superior over the conventional two port single-input single-output interfacing structure. Motivated by these, this article considers a four-port DC-DC converter (FPC) design, which accommodates fuel cell (FC), battery bank (BB), solar photovoltaic (SPV) system, and DC load at its ports. The presented work formulates linear state-space model of the considered FPC. In this formulation, small signal modeling of the FPC is done from the detailed model of the latter. The process of obtaining a small signal model requires linearization of corresponding large signal models. Finally, the work compares large, and small signal responses of states of state-space model of the FPC.

The aim of the work is to develop a reliable composite DGA (Dissolved Gas Analysis) based method to diagnose single and multiple transformer incipient faults. To achieve this objective a two-stage model is proposed. The first stage of the model is the ANN implementation of Dornenburg, Rogers ratio, CEGB, IEC, and Duval triangle methods. ANN-based implementation is carried out to circumvent limitations of the considered methods. Further, to resolve the conflicts of the first stage diagnosis and to predict the most probable single or multiple faults an intelligent rule-based scheme is developed as the second stage of the integrated model. The idea is to exploit the strengths of the different DGA methods to converge to a more reliable diagnostic method using intelligent integrating rules. The proposed method is found to be more reliable and comprehensive in comparison to contemporary methods.

Nowadays, focus on renewable energy sources (solar, wind, biogas etc.), especially on solar energy is to find the best alternative source of energy due to being hazardous free, pollution free, never end and abundant in nature etc. A photovoltaic (PV) systems (stand-alone, grid-connected or hybrid PV systems) consisting of many vulnerable components like module, connecting cable, fuse, diode, a power conditioning device etc., a fault in any components can lead to degradation of efficiency, energy output as well as the reliability of the overall PV systems, if not prior corrective action takes place. So, Fault detection and it’s ranking for PV systems, especially focus on PV module, because it operates very harsh condition, plays a vital role for the system reliability and safety. In this research work, fault ranking in PV module has been done based on artificial intelligence (AIT) technique. Thus, fuzzy logic is applied to assess the critical fault in the PV module, according to their ranking. Fault possibilities in PV module are expressed by linguistic variables. A consistency agreement method technique has been used for aggregation of fuzzy number, assigned by the experts. The proposed method is best for ranking of occurrence of a fault in the PV module.

Power System State Estimation is used to estimate the states of power system. Conventionally, state estimation is an offline method for visualization of power system states. Microgrid are dynamic networks with rapidly changing scenarios. The offline or static state estimates fall behind the actual states of microgrid. Thus, this paper proposes a real time state estimation for microgrids using synchrophasors. Due to high sampling rates of PMU, the data measured through it provide the means for online visualization of microgrid. The real time state estimation is implemented using PMU in Real Time Digital Simulator (RTDS) environment. The proposed method is applied on a modified 14 bus test microgrid. The results are compared with the static estimation and it has been found that the real time state estimation provide accurate visualization of microgrid states than offline state estimation.

Even phase drives in conjunction with multiphase matrix converter is a smart solution in connecting them to a three-phase source. It reduces the area required to install such drive due to the omission of bulky dc-link capacitor. This work concentrates on a mathematical solution to the equations that pertain to such a converter. Venturini method is taken as the basis of analysis. It is found that a mathematical solution does exist for an even-phase output converter only when the number of inputs is three. The theory is then supported with simulation as well as experimental results on $3 times 6$ Matrix Converter.

Nowadays, Feeder automation (FA) is the fastest growing trend among utilities to enhance the reliability of distribution networks. One of the main applications of feeder automation is automatic fault management (AFM). AFM function comprises sequential steps of fault detection, isolation and service restoration (FDISR) following a contingency in distribution networks. The allocation of automated protective devices such as circuit breakers, reclosers, remote-controlled switches, fault indicators speeds up the FDISR process. A high level of reliability is ensured by utilizing an appropriate combination of these devices but this is limited by cost constraints. Aiming to achieve an optimum reliability level, this paper presents an analytical model that incorporates protective devices, viz. reclosers (${R}$) and remote-controlled switches (RCS) at optimal positions of a radial distribution system. Cost worth analysis is utilized to develop the proposed model. Moreover, in the competitive restructuring and deregulated environment, the main aim of the utilities is to maximize their profit. The objective of the proposed model is developed from the utilities’ perspective, utilizing the profit-based optimization approach. The proposed model is tested on a 58-bus test system employing the mixed-integer non-linear programming (MINLP) optimization technique. Reliability indices have also been measured to explore the level of reliability enhancement achieved by automation. The simulation results have verified the practicality and relevance of the proposed approach in maximizing profit as well as in raising the reliability level.
