The possible services of batteries are expanding within the scope of transforming electricity networks. In this study, the potential of batteries to increase transformer efficiency is revealed. It is aimed to maximize the transformer efficiency depending on the demand and the installed power of the transformer. Based on this aim, optimization algorithms that can decide on the optimal battery size are developed. The daily charge-discharge cycle of the battery within the scope of transformer efficiency is explained. According to the pilot site studies carried out, up to 22% efficiency increase potential is discovered in a transformer with the battery. Considering this potential, the use of batteries to support transformer efficiency is recommended as a new local service concept.

This paper presents an investigation into overvoltage issues triggered by distributed energy resources (DERs) tripping. The expected voltages are presented from initial planning criteria based on slack bus modelling of the transmission substation. Results demonstrate that transmission voltage fluctuations are exacerbated at weak substation distribution buses. Results are determined through actual system measurements and simulation in the CYME software.

High penetration of renewable energy sources (RESs) may contribute to power system oscillations due to diminished inertia, while communication networks generate time delays that can compromise system performance and induce frequency fluctuations. This paper uses Rekasius substitution to compute the stability delay margin of an islanded micro grid (MG) with virtual inertia (VI) and constant communication delay. For a finite positive time delay, the approach seeks to find all possible purely complex roots of the characteristic equation. The method starts by converting the transcendental terms in the characteristic polynomial into a regular polynomial. After that, the Routh-Hurwitz Stability Criterion is used to calculate the purely imaginary roots with the crossing frequency and stability delay margin. Time delay values at which the MG is marginally stable are estimated for a wide range of proportional-integral (PI) controller gains. Accuracy of results is verified using quasi-polynomial mapping-based root finder (QPmR) algorithm and time-domain simulations in Matlab/Simulink.

Smart building technologies transform buildings into agile, sustainable, and health-conscious ecosystems by leveraging IoT platforms. In this regard, we have developed a Persuasive Energy Conscious Network (PECN) at the University of Glasgow to understand the user-centric energy consumption patterns in an agile workspace. PECN consists of desk-level energy monitoring sensors that enable us to develop user-centric models that can be exploited to characterize the normal energy usage behavior of an office occupant. In this study, we make use of staked long short-term memory (LSTM) to forecast future energy demands. Moreover, we employed statistical techniques to automate the detection of anomalous power consumption patterns. Our experimental results indicate that post-anomaly resolution leads to 6.37% improvement in the forecasting accuracy.

The industrial 18650 li-ion cells have been extensively used in portable devices, electric vehicles (EVs), military applications etc. Especially the state of health (SOH) parameter of the li-ion cells is quite important for these devices or systems in terms of durability and safety. On this matter, the change of internal resistance is used as a feature to track battery SOH. Thus, we comparatively observed both AC and DC internal resistance methods to see which method has strong relationship individually. The results have shown that AC impedance measurement is highly dependent to internal and external status of cell while DC resistance measurements give us more precise results under the limited test abilities such as control of cell internal temperature. This could give advantage for basic battery management modules which cannot be able to handle complex analysis and reach internal status of the cell.

In this paper, fractional order PID (FOPID) optimized with seagull optimization algorithm (SOA) is designed as a secondary regulator for load frequency control (LFC) of the interconnected power system (IPS). However, the efficacy of FOPID is showcased with other integral order type classical controllers. IPS deliberated in this work is a widely used model of dual area hydro-thermal (DAHT) upon laying 10% perturbation of step load on area-1 (10%SLP) for investigation. Further, plug-in-electric vehicles (PEVs) are integrated into area-1 of DAHT for analysis purposes. DAHT responses are enhanced with the integration of PEVs. Later, the control areas of DAHT are incorporated with superconducting magnetic energy storage (SMES) devices to get further enhancement in system stability. Finally, simulation results reveal the superiority of implementing PEVs and SMES coordinated strategies for improvement in frequency regulation.

This article presents an efficient control strategy based on a Tilt-Integral-Derivative (TID) controller gains to face future problems related to modern power systems. Nowadays, most of the problems relate to the high penetration percentage of renewable energy sources (RESs) to the power grid. The studied system is a composite of the two-area interconnected power systems. Each area is served by a combination of traditional units (i.e., a thermal unit, a hydro unit, and a gas unit). Furthermore, renewable power penetration has been considered in the two areas to form a hybrid power system. Moreover, a new meta-heuristic optimization algorithm named the weighted mean of vectors (INFO) has been applied to fine-tune the parameters of the proposed TID controller. The proposed TID controller is utilized to support the frequency stability of two-area multi-sources compared to other controllers in previous studies (i.e., PID controller in alignment with teaching learning-based optimization (TLBO) and TID based on interpretative phenomenological analysis (IPA)) under different operating conditions. Additionally, the challenge of high RESs penetrating is proposed to test the TID controller effectiveness in achieving more stability in the targeted electricity network. The investigated simulation results are carried out utilizing the MATLAB/SIMULINK program, and these results elucidate that the proposed TID controller based on the INFO algorithm can enhance the frequency stability effectively while guaranteeing reliable performance considering various perturbations.

This work discusses measurements and modeling of conducted emissions in the time and frequency domain to evaluate the impact of common DC/DC converters existing on DC grids. Variable DC input voltages are used to study the influence of input voltage on the LISN and conducted emissions. The time-frequency domain was shown to provide extra information to assess conducted emissions in addition to the time- and frequency-domain representations. PSIM software was used to model the system, and MATLAB was used to analyze the signals. Short-time Fourier transform (STFT) and spectrogram of the signal have been employed for the evaluation of conducted emissions. According to the results when the input voltage rose, the amplitude of the transmitted propagation decreased. In the future, the findings might be applied to the design of EMI filters.

In this study, the effect of fluid damping on the performance of a 2-pole, 4-kW line start synchronous reluctance machine (LS-SynRM) with different slot opening structures for submersible water pump applications is investigated. Since the submersible pump motors run inside a fluid-filled environment and the fluid viscosity and density differ from the air, it causes an increased damping effect comparing air-filled machines. Hence, a non-negligible damping loss occurs. In this study, the damping effects of the fluids in a 24 slot LS-SynRM for various stator slot indentations are investigated with computational fluid dynamics (CFD) finite element analysis (FEA) to highlight the importance of the fluid damping loss in flooded machines. Results show that the damping loss can go as high as 10% of the motor output power when the stator surface has indentations, and this loss can be cut down to 3.5 % when the surface indentations are eliminated with custom no-slotting wedge structures.

In this paper, an Electric Vehicle (EV) aggregator is included both primary and secondary frequency control loops of a single-area Load Frequency Control (LFC) system via the droop coefficient and participation factor, respectively. Then, its impact on the stability regions in controller parameter space is investigated in detail. The effect of the Gain and Phase Margin Tester (GPMT) coefficients and integrator order of the Fractional-Order PI (FOPI) controller on the stability region are also examined. Finally, MATLAB-Simulink-based studies prove that the EV aggregator contributes positively to the stability regions under the LFC-EV concept.
