This work presents the implementation of Thyristor controlled phase shifter (TCPS) and superconducting magnetic energy storage (SMES) as an effective supplementary control strategy in the interconnected power system (IPS) stability. Dual area traditional hydro-thermal (DATHT) is selected as the investigative IPS model and carried out the analysis for 10% step load disturbance (SLD) in area 1. Fruit fly technique (FFT) based tilt-integral-derivative-filter (TIDN) is enacted for the DATHT system as a secondary regulator. Time delays (TDs) are conceived with the DATHT system to get a more practical investigation and their impact on performance is also demonstrated. Later, the investigation is stretched to the adoption of TCPS-SMES control and the simulation analysis reveals the enhancement in DATHT performance.

Natural dust accumulation on the installed solar photovoltaic (PV) modules reduces the transmittance, thereby degrading the conversion efficiency of solar PV plants. Therefore, proper monitoring and cleaning of solar modules are necessary to ensure the efficient performance of solar PV modules. For new installations, the prediction of performance is needed based on the already installed sight-specific PV plant data. In this work, Machine Learning (ML) algorithms have been used to predict the transmittance of solar PV module surface under the impact of natural dust accumulation over seasonal variations. Annual experimental dataset from solar PV modules surface (low-iron glass) has been utilized to predict the transmittance using ML algorithms such as K-Nearest Neighbour (KNN), Decision Tree, Random Forest, and Ensemble learning (EL) - Gradient Boost algorithm, on three different tilt positions: horizontal, inclined and vertical positions. A detailed comparative analysis of different ML models for different glass positions using performance evaluation metrics has shown that the ensemble learning-based Gradient boost algorithm is the most accurate in predicting the optical performance of solar modules with R2, MAE, RMSE, and MAPE values of 0.99, 0.736, 0.55 and 0.7% respectively. The prediction results obtained in this work claim to be useful for optimal scheduling of cleaning the solar modules to improve the overall performance of site-specific solar power plants.

In literature, the use of passive electromagnetic interference (EMI) filters is extensively researched to not only restrain the common-mode (CM) noise but also the differential-mode (DM) noise. Although the CM and DM chokes are simple to design, reliable, and do not need an auxiliary power supply, they increase the overall volume and reduce the power density of a power converter. Hence, this paper presents a novel integrated choke that offers higher DM impedance than the traditional CM choke by maintaining the same volume, when compared to the traditional CM choke. The calculation of CM inductance, as well as DM inductance of the proposed integrated filter topology, is presented along with a small signal measurement using an impedance analyzer. The proposed EMI filter performance is verified on a three-phase silicon carbide (SiC) fed brushless dc (BLdc) motor.

In 21st century world is dedicated to reduce carbon emission in the environment. For this purpose, it is essential to reduce the uses of conventional sources of energy. To achieve this, the global transportation network is evolving rapidly from traditional to electrical vehicle (EV). As penetration of EVs in market is increasing gradually, energy demand is also increasing which infuse extra load on power grid. Also, the complete dependency on power grid means you also have to buy power even when price is on peak. As the ultimate goal of parking lot owner is to maximize his profit so it is not convenient to buy power from grid when prices are high. To attain more profit, it is required to charge more vehicles that may lead to expand the availability of charging slots but again it is very challenging and not recommended due to strict regulations from authorities for network upgrades. To charge more electric vehicles and to reduce power drawn from the grid, a small-scale energy resource (SSER) is introduced in this study i.e. Solar PV Plant. In coordinated case, preferable source of power is solar. When solar is abundant, EVs are charged by solar power and in result of this power drawn from grid decreases and profit of parking lot owner increases. From the findings, it can be seen that when using solar, power purchasing cost per day is reduced by 64.78$ or 28.5% which shows the significance of using solar as SSER.

This paper makes a proposal for a unified active power filter (UAPF) to reduce the total harmonic distortion (THD) in low voltage distribution networks. Thus, a photovoltaic (PV) generation is used as the UAPF's source, along with a boost converter. A non-linear load is in the seventh bus-bar of the IEEE 13-bar system, which serves as the test bench. discussing the effects of the system's voltage, current, and THD. As a result, the harmonics of the current (THDi) and voltage (THDv) decreased; they were reduced to 6 and 3 percentage points, respectively. The outcomes are within the parameters specified by the ARCERNNR -017/2020 resolution and IEEE 1159 standards.

Power Energy quality is determined by providing users with a service that is effective and meets their expectations. This calls for optimizing the core operations of an electrical power system, such as generation, transmission, and distribution. Energy is essential for the efficient operation of a nation's productive matrix as well as the performance of essential functions in our homes. This document's objective is the analysis and implementation of vector space control in photovoltaic distributed generation inverters on an IEEE 34-bar system with the goal of minimizing total harmonic distortion (THD), which is typically produced by everyday electronic devices connected to the electrical system. This document's premise is to improve the quality of the distribution network. A complete bridge inverter attached to the system's bus-bar number 25 is modulated using the control of six fundamental vectors. Since both modulation strategies in the integrated DG in THPWM and SVPWM improve the stability characteristics of the suggested distribution network, it is concluded that the results obtained are consistent with predictions.

An efficient DC-DC power converter capable of operating for wide input variation is essential for applications involving PV based systems. This is due to changes in irradiation, partial shading, temperature, and many other conditions resulting in large fluctuations in PV voltage. Additionally, the converter should be able to give high steady state gain while operating at minimum input voltage. In this work, a high gain LCLC resonant converter with reduced transformer turns ratio, and high power conversion efficiency is considered for solar photovoltaic (PV) to grid application. The presence of a voltage doubler secondary ensures a reduced turns ratio results in a smaller transformer size and minimizes the transformer parasitic. Frequency and phase shift control based hybrid modulation technique is incorporated to establish high voltage dc bus from wide varying PV source. The converter is analysed theoretically at various operating modes and the performance is evaluated with the help of a 500 W experimental prototype.

With the advent of smart protection devices, the utilities have started giving importance to single/double phase tripping for distribution system and microgrid, for which an accurate faulty phase selection is required. Incorporating more inverter-based distributed generation has increased the complexity for the protection devices to select the faulty phases accurately. The inverter-based distributed generations (DGs) show a different fault behavior compared to traditional synchronous-based machines, making the faulty phase selection difficult for the protection devices. This paper briefs the failure of some existing methods to identify the faulty phase and proposes a solution for the problem with a detailed explanation. The effectiveness of the method is tested on a 5-bus system with two photovoltaic distributed generations (DGs)and the results validate that the proposed method successfully selects the faulty phase.

This paper aims at the dynamic modelling of the Peltier module with cooling load and heat sink. The governing equation for the system is derived and linearized with the induced perturbation to the variable quantities. Laplace transform is applied to the governing equations to obtain the transfer function, which accounts for the dynamics of the Peltier module system. The exact transfer function of the system demands a series expansion of a few terms, which results in a multi-order system with a larger number of poles. So, from an analytical point of view transfer function is reduced to second order system with optimal assumptions. Mathematical derivation is provided for this system which explains the physical essence of the transfer function having one zero and two poles and depends on the operating conditions.
