Almost all the sixth-generation (6G) non-orthogonal multiple access (NOMA)-based research assumes a perfect successive interference cancelation (SIC) when it comes to system analysis or planning; this assumption should be supported by advanced schemes that consider the suggested technologies and THz characteristics. The work in this paper proposes an optimized two-user pairing scheme where simultaneous wireless information and power transfer (SWIPT) is adopted with cooperative hybrid-NOMA (H-NOMA) in terahertz (THz) considering SIC imperfection. The aim is to improve the overall performance of wireless THz communication networks including wireless connectivity, resource management, scalability, and user fairness. Hence, thorough studies for a number of SWIPT-NOMA schemes were presented alongside a selection of the best H-NOMA pairing strategy for the served users. We investigated system performance according to SIC manipulation to develop a proper SWIPT-based simplified system. The results showed a remarkable improvement in energy efficiency and spectral efficiency compared to conventional work (NOMA and OMA time division multiple access (TDMA)) by 75%. This promising proposal has a positive impact on reducing system hardware, complexity, and cost while improving signal detection, diversity, and reliability, without the need for complicated techniques such as multiple-input multiple-output (MIMO).

Control design for pressurized water reactor (PWR) is difficult due to associated non-linearity, modelling uncertainties and time-varying system parameters. Extended state observer (ESO) based active disturbance rejection control (ADRC) presents a simple and robust control solution which is almost model free and has few tuning parameters. However, conventional ESO suffers from noise over-amplification in the obtained estimates due to high-gain construction which in turn degrades the noise sensitivity of the closed-loop system and limits the achievable dynamic performance in practical scenarios. To overcome this problem, two recent techniques namely cascade ESO (CESO) and low-power higher-order ESO (LHESO) are implemented for control of PWR. Simulation analysis conducted in MATLAB illustrates the performance improvement obtained over conventional ESO based ADRC. Extensive simulation analysis is also conducted to investigate robustness towards parametric uncertainties.

Recent growth in Electric vehicles (EV) has led to EV batteries being seen as potential energy storage devices and power sources with the advent of vehicle-to-grid (V2G) and grid-to-vehicle (G2V) technology. EV batteries can aid in improving overall efficiency of the system. The paper proposes a V2G/G2V model which consists of a bi-directional grid connected converter, off-board chargers, EV batteries, and filters utilising standard DC charging for effective power sharing, control, and regulation. The control of the chargers decides the priority of the source based on the set threshold level and subsequently integrates with the circuit. The converter processes the signals without external interference like communication links. The V2G/G2V concept is designed, modelled, and visualized in MATLAB/Simulink, and the various results indicate the potential for better energy utilization and energy trade between individual players.

Expanding adoption of electric vehicles (EVs) and broad deployment of charging stations push the limits of distribution grid infrastructure and increase the importance of effective charging coordination. Smart EV chargers with several functionalities and charging coordination solutions that can manage the charging sessions of hundreds of EVs are becoming common, with the increasing risk of triggering significant operational problems in case of cyberattacks. The information exchange between the charging coordinator, distribution network operator, and users is essential in the scheduling of a large number of charging sessions, relying on customer preferences, without violating operational grid constraints. Both the user mobile apps used for charging session reservations and DSO-charging coordinator interfaces are vulnerable to cyberattacks which may cause considerable technical and economic consequences. An important concern is the potential impacts of attacks when a single node or communication link is compromised. This study investigates the impacts of false data injection (FDI) and hijacking attacks on EV charging coordination in case of a single point of failure. Hijacking of one user’s mobile app and FDI attack on the DSO-charging coordinator interface are investigated by simulating a 24-hour scenario with 12 chargers, 34 realistic charging sessions, and an EV charging coordination approach based on each session’s tolerance to delays. The study highlighted considerable negative impacts that could be encountered in case of a single point of failure in EV charging coordination.

The computational burden and the time required to train a deep reinforcement learning (DRL) can be appreciable, especially for the particular case of a DRL control used for frequency control of multi-electrical energy storage (MEESS). This paper presents an assessment of four training configurations of the actor and critic network to determine the configuration training that produces the lower computational time, considering the specific case of frequency control of MEESS. The training configuration cases are defined considering two processing units: CPU and GPU and are evaluated considering serial and parallel computing using MATLAB® 2020b Parallel Computing Toolbox. The agent used for this assessment is the Deep Deterministic Policy Gradient (DDPG) agent. The environment represents the dynamic model to provide enhanced frequency response to the power system by controlling the state of charge of energy storage systems. Simulation results demonstrated that the best configuration to reduce the computational time is training both actor and critic network on CPU using parallel computing.

Although many smart grid authentication protocols have been presented in literature, majority of them remain susceptible to numerous attacks. In addition, some of these protocols are based on computationally intensive cryptographic primitives, which render them inefficient. To address some of these challenges, a protocol based on masked symmetric key encrypted verification codes is presented in this paper. The security analysis carried out shows that this protocol provides message confidentiality, unlinkability, and traceability for malicious network entities. It is also resilient against side-channel and forgery attacks. In terms of efficiency, limited numbers of elliptic curve multiplication and one way-hashing operations are executed during mutual authentication, message signing and verification. As such, this protocol exhibits the least computation and communication complexities in comparison with its peers.

It is very evident that the number of electric vehicles worldwide will increase and that the dominant mobility concept in the future will be at the center of EVs. As a requirement of e-mobility, EVs should be rechargeable anywhere and in any situation, and this will increase EV-based electrification. The effects of EV charging stations on the grid are very important in the increasing electricity demand level and the installation of EV charging stations on distribution transformers (DTs) should be balanced and should not have negative effects on the transformer. This paper aims to determine the number of EV charging stations to be loaded on distribution transformers in an optimized and safe manner. The data of 8361 distribution transformers in the Central Anatolian Region were collected and analyzed. Data verification was completed with data cleansing methods and an effective EV charging station installation modeling was developed. By modeling with three different risk levels, it is possible to determine which distribution transformer will be installed from four different EV charging socket types. The general situation of DTs in the region was determined with the pilot region application. Basic data can be revealed by modeling which region can be improved for the EV infrastructure going forward.

This paper proposes a dv/dt suppression second-order RLC filter for an inverter-cable-high impedance load system. The dv/dt filter placed at the inverter output is designed purposely to minimize excessive voltage overshoot at the load terminal by reducing dv/dt or voltage pulse rise time. A 500 V unit pulse of inverter source is connected over several cable lengths to a high impedance load with a load reflection coefficient of 0.9. Voltage overshoot in terms of the ratio of rise time to propagation time is analyzed and verified by Matlab/Simulink environment. In addition, a new design method for the second-order dv/dt filter is proposed. From the simulation results, the dv/dt filter is able to reduce a high load peak voltage of approximately 950 V to 588.6 V in a 50m inverter-cable-load system, and increase to 1 µs of rise time at the load terminal.

In addition, a new design method for the second-order dv/dt filter is proposed. From the simulation results, the dv/dt filter is able to reduce a high load peak voltage of approximately 950 V to 588.6 V in a 50m inverter-cable-load system, and increase to 1 µs of rise time at the load terminal.","PeriodicalId":441321,"journal":{"name":"2022 4th Global Power, Energy and Communication Conference (GPECOM)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131798107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
