The use of special conductive clothing during transmission line maintenance work on the passive side of a double-circuit line can protect the worker in the event of an accident. Recently, methods have been developed for the testing of such clothing, including annual inspections. However, the resistance of certain parts of the clothing (e.g. gloves) can be greatly increased due to wearing. Our investigations have extended to a more detailed study of conductive gloves, using a garment-body model and assuming induced current switching, we present the results of different scenarios. The study suggests that, in the event of an accident, some currents can flow through the human body depending on which part of the worker's clothing is touching the wire.

The high penetration of distributed renewable energy resources (DERs) and various fast increasing direct current (DC) loads significantly facilitate the development of low voltage DC (LVDC) systems. Novel power electronic devices further provide opportunities for the flexible interconnection of alternating current (AC) and DC networks. However, there is still a lack of international standards concerning DC power quality. In addition, it is not clear whether the relevant power quality research applies to the LVDC systems. In this paper, a definition of the DC power quality issues is given based on the existing IEC and IEEE standards and codes and the detailed reasons for the typical DC power quality events. Then, the correlation between DC power quality phenomena, which plays an essential role in the formulation of DC power quality standards, is illustrated and quantified. Moreover, the influence on DC ripple, DC unbalance and oscillation with AC/DC interconnection is analyzed. The resulting comparative study in this paper provides a reference for formulating the definitions and constraints of LVDC power quality issues, which could strongly support the future DC power quality standard enaction.

Due to increasing penetration of renewable energy-based distributed generation (DG), conventional distribution networks are transformed into their active form, where microgrids are considered fundamental building blocks. Optimal placement of DG units is the primary step towards microgrid planning. Optimally placed and sized DGs can reduce the total power losses in distribution networks by localizing the power supply to loads. In this paper, a DG optimal placement method by minimizing the total power losses is proposed, where Brute Force search algorithm and Backward Forward Sweep method are used to solve the optimization and load flow problems, respectively. IEEE 33 bus radial distribution test system is used to validate the proposed method in MATLAB. Several case studies are conducted, dispatchable and non-dispatchable DGs and capacitor banks are used in the optimal placement and sizing. The proposed method is proved to be effective by comparing with an existing method.

Since communication channels of microgrids (MGs) are prone to environmental noises, control signals used in distributed control architecture will also be polluted. To solve this challenging task, noises in communication channels need to be considered in distributed control of MGs. In this paper, distributed noise-resilient fixed-time consensus-based secondary control of hybrid inverter-based AC/DC MGs is proposed to achieve autonomous power sharing, frequency synchronization, and voltage restoration simultaneouly. One major benefit of the proposed fixed-time control is that the converging time is indeed independent of the initial condition. Thus, the settling time can be elaborately designated off-line according to specification requirements. To demonstrate the effectiveness of the proposed method, simulation studies under MATLAB/Simulink environments of a 6-bus hybrid inverter-based AC/DC MG are performed. Scenar-ios under load variations, communication channel with additive noise, and plug-and-play operations of distributed generators are investigated. Comparison studies with other variants of distributed consensus control are also investigated to demonstrate the effectiveness of the proposed distributed secondary control.

Coal fill level in coke ovens is very important in the production of coke. A well charged oven is key to the efficiency of the process and undercharged coke ovens result in a massive lost in the volume of produced coke in time. There is no common method to measure the fill level of ovens in coke plants more than visual inspection or just assuming that the volume of coal in the charging cars will be the precise for the process, this often result in undercharged ovens. This paper presents a system based in a wireless capacitive sensor capable of withstand the high temperatures of an oven, usually above $boldsymbol{600}^{circ}mathbf{C}$, and measure the coal fill level of the full length of the oven. The paper also shows results collected in various coke plants worldwide.

This paper develops a survivability-based protection for three phase permanent magnet synchronous motor drives against severe dynamic events. The proposed protection is based on defining a survivability index * PMsM that is expressed in terms of power changes resulting from a dynamic event, which is experi-enced by the protected motor drive. The index *PMSM establishes an accurate measure to detect, identify, and respond to dynamic events that a three phase permanent magnet synchronous motor drive may not survive. The validity, effectiveness, and accuracy of the survivability-based protection for three phase permanent magnet synchronous motor drives are assessed through simulation and experimental testing. Assessment tests are carried out using a 10hp laboratory three phase permanent magnet synchronous motor drive under various dynamic events. Assessment results demonstrate the efficacy and responsiveness of the survivability-based protection to unsurvivable dynamic events, and its ability to prevent damage to different components of a three phase permanent magnet synchronous motor drive.

This paper presents an enhanced adaptive fourth order generalized integrator with frequency locked loop (EAFOGI-FLL) based control that improves the power quality of a solar photovoltaic system (SPVS) in grid-connected mode (GCM) and standalone mode (SAM), ensures seamless operation, makes the grid currents sinusoidal and, also eliminates DC offset. It ensures unity power factor (UPF) operation of the grid to minimize line losses. The control maintains the point of common coupling (PCC) voltages sinusoidal in GCM and SAM even in the presence of nonlinear loads. The FLL enables effective frequency tracking with grid frequency variations and makes the system adaptive. The SPVS is run in maximum power point tracking (MPPT) mode in GCM and, with an improved control in SAM to ensure power balance. The system is analyzed using a developed simulink model in different conditions.

Cybersecurity has become a crucial consideration in critical power system applications such as automatic gener-ation control (AGC) due to the increasing use of information and communication technology. The existing research literature includes several descriptions of threats from either physics-based or pure cybersecurity perspectives. A holistic cyber-physical security assessment method is necessary to guide future decisions regarding AGC organization. This paper develops an analytical risk assessment method for integrity attacks on AGC communication while considering the cyber-physical causal chain. Attack occurrences and detections are modeled as stochastic events, while considering their physical impact and modeling accuracy of mitigation measures. The results provide a holistic cyber-physical security assessment and recommendations for securing the AGC system against compromised communications.

An automatic bus transfer scheme (ABTS) is a conventional method of supplying power to a load by safely transferring motor loads to an alternate healthy source if the primary source fails. State-of-the-art bus transfer schemes can be improved significantly by using intelligent electronic devices (IEDs) and communication standard IEC 61850 to supply uninterrupted power to customers. In this work, an intelligent distribution bus automatic transfer scheme (IDBATS) is proposed, which leverages the use of generic object-oriented substation event (GOOSE) messages. The scheme prevents the power transformer from overloading, and it can be implemented on a substation regardless of the network configuration and load demand. Since the protection logic is kept in the master IED, the scheme can include any new transformers added to the substation network. The IDBATS scheme was validated on a 230 kV/34.5 kV distribution substation by conducting a hardware-in-the-loop simulation using real-time digital simulator (RTDS).

This paper presents the hybrid simulation technique to efficiently analyze the impact of high PV penetration on the distribution system. The proposed approach utilizes the multi-domain simulation capability of Matlab/Simulink software to simulate the tested system in the Electromagnetic Transient (EMT) and Phasor domains. The detailed switching models of several PV inverters are modeled in the EMT domain, while the rest, including other PV inverters and the grid, are modeled in the Phasor domain. An interaction method is proposed to handle data transferring between EMT and Phasor sub-systems. The modified IEEE 13-node distribution grid with several units of a two-stage single-phase smart PV inverter is used to validate the proposed technique. Several transient studies are carried out to analyze the accuracy and efficiency of the proposed hybrid method and compared with the full EMT model. Simulation results show that the proposed approach significantly reduces the computation time and retains sufficient accuracy as compared to full EMT model.
