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.

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.

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.

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).

The smart electric grid with enhanced renewable energy (RE) integration is facing the inherent RE uncertainty and intermittency. As one of the widely deployed intelligence electronic devices in the power grid, the Phasor Measurement Units (PMUs) support the requirements of closely monitoring dynamic signals and possibly help with automated control. However, Discrete Fourier Transform (DFT) for estimating phasor for a common fundamental frequency (50/60 Hz) in PMUs is not applicable for capturing dynamic disturbance under non-nominal frequency conditions of the smart grids. The operating conditions of the smart grid are more dynamic than the traditional power grid, and the attenuated phasors can also be produced if it operates at an undesired frequency during oscillations or dynamic events. This paper presents a novel adaptive phasor estimation algorithm based on Wavelet Transform (WT), which utilizes Energy Theory to dynamically switch between the best options to enhance the performance of PMU based applications. The proposed method is validated and tested using Simulink model, and the results indicates that the proposed method has high accuracy and robustness in phasor estimation and industrial applications.

Large-scale integration of distributed energy resources (DER) in the power distribution grid leads to the possible operation of multiple microgrids (MG). DER management system (DERMS) is responsible for the optimal network configuration, dispatch of DERs, and providing appropriate set-points for the DERs. The network of multiple MGs needs to be reconfigured dynamically when extreme events occur in the distribution grid. Reinforcement learning methods are used in various optimal energy management, and dispatch of DERs. Q-routing is a reinforcement learning-based method to discover the optimal path between source and destination nodes. Since in networked MGs, each MG can have multiple boundaries, the Q-routing algorithm is enhanced with a reward mechanism depending on the events in the distribution grid. In this paper, extended Q-routing-based dynamic reconfiguration of a networked MG is proposed including the event-driven TCP/IP communication. Real-time results validate the effectiveness of the proposed framework for various reconfiguration test cases.

This research presents a risk-based energy management system (EMS) for an islanded microgrid, considering each system component's probability of failure (PoF). A scenario-based optimization method has been used to include uncertain events in the problem formulation. The loads are categorized as critical, semi-critical, or noncritical to prioritize supplying the crucial loads when the microgrid's generation is insufficient to meet the load demand. Additionally, the nonlinear power flow equation has been transformed into convex equations, cutting down the computational time. Then the proposed method is applied to the modified IEEE-14 bus system. The result showed that the risk-based EMS reduced the amount of load served than a normal EMS, depending on the PoF of each system component. In addition, the EMS served critical loads first, then semi-critical loads, and practically curtailed all non-critical loads to match the generation and the demand. This successive load curtailment increases the microgrid's likelihood of survival in the islanded mode.

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.

This paper presents a novel high voltage pulse power generator layout that is well suited to dielectric barrier discharge applications. To reach the higher gain, a push-pull circuit with a three-winding transformer is used on the charging side, along with quasi-resonant between the transformer leakage inductance and the capacitor on the high-voltage section. The primary side's two windings and two low voltage switches allow the gadget to generate either unipolar or bipolar high voltage exponential pulses from an approximately low DC source. Instead of a bidirectional switch, a magnet one is employed since it eliminates the concerns of series and parallel connections of semiconductor switches in high voltage side, resulting in a low degree of switching complexity. Hence, In addition to accomplishing the high gain objective, the effort focuses on lowering the number of circuit elements and control complexity in contrast to previous topologies. The generator operates in discontinuous conduction mode, which improves the system efficiency by allowing for the generation of full positive and/or negative waves while it also reduces the conduction losses. The operation phases of the pulse generator are detailed. It is found from the simulation results that the proposed pulse generator outperforms the previous structures in terms of control complexity, number of switches, and flexibility.
