High Voltage dc (HVdc) transmission systems have gained increased popularity as a flexible and efficient power transmission option with higher grid controllability. Widespread adoption of HVdc systems for interconnecting power systems and integrating large renewable energy generation facilities such as wind farms, has forced the power system to undergo a transition from a predominantly ac system into a hybrid ac-dc system, specially in the high voltage transmission grid. This paper attempts to provide an overview on the role of Voltage Source Converter based HVdc(VSC-HVdc) systems within the evolving power system as a grid services provider. Special attention is paid to discuss the impact of Grid Forming converter control approach on the provision of such services through VSC-HVdc systems.

Solid-state transformers (SSTs) can provide various advanced functions to support the stable, flexible, and resilient operation of modern power grids. To enhance the power rating and the controllability of SSTs at the distribution substation level, a hybrid SST (HSST) is proposed recently where the line-frequency transformer (LFT) is combined with the SST to process the major power flow while the SST section supports advanced grid control functions. In this paper, the voltage regulation and the power flow regulation control functions of HSST are developed by using discrete-set model predictive control (MPC). Various test cases are designed and validated in the PLECS environment.

Ransomware attacks are one of the most dangerous cyber-attacks which can disrupt the operation of photovoltaic (PV) systems and incur an enormous economic loss. This paper introduces a ransomware security threat modeling method that identifies potential vulnerabilities, threats, and impacts of ransomware attacks targeting a PV system. The security threat modeling consists of three steps: 1) system identification, 2) threat modeling that finds existing vulnerabilities, 3) attack modeling that designs attack profiles to succeed ransomware attacks, and 4) penetration testing that performs authorized cyber-attacks and analyzes impacts of the ransomware attack profiles using a real-time hardware-in-the-loop (HIL) PV system security testbed.

Providing fast frequency regulation by means of energy storage systems is currently considered as a viable solution to low-inertia issues, caused by power electronics-interfaced generators. In particular, hybrid energy storage systems, composed by more energy storage technologies having different power and energy ratings, can optimally support the frequency regulation. A supercapacitor/battery storage system, for example, can exploit the supercapacitor dynamic active power response for synthetic inertia control, while the battery can provide primary and secondary frequency regulation. However, the optimal energy management of hybrid energy storage systems during transients needs to be addressed further in literature. In this paper, a State of Charge (SOC) feedback control scheme is proposed, that adjusts the active power output reference depending on the state of charge, avoiding excessive stress on the components and limiting the state of charge excursions. Control system parameters are optimally tuned minimizing a weighted multi-objective function in the solution of an optimal control problem. Test results adopting different weights are presented and discussed.

Smart solid-state Transformer (ST) is an emerging technology that targets to modernize the electricity grids and to facilitate the integration of low carbon technologies (PV, EV charging station and storage). The ST performances in terms of services provision, reliability, cost and efficiency, are depended on its architecture and topology, besides the advanced control strategies. The modular architecture has the advantages in reliability, maintenance and scalability in the medium voltage grid applications. This paper comprehensively analyzes and compares the modular multilevel converter solutions for ST, based on the literature and industry survey, highlighting the advantages and disadvantages for each topology. Based on the position of dc/dc stage, the ST topology is classified into two different types. Particular focus has been given to the dc connectivity provision at different voltage level, the required number of building blocks, scalability and fault tolerance.

With the increasing penetration of power converters-interfaced resources in the modern networks, the electricity grids may suffer from the electromagnetic interference (EMI) issues, which result in the voltage surges and transients, threatening the reliable operation of the adjacent sensitive devices. In this paper, the EMI performances of the back-to-back converters, taken into account the impacts of switching frequency, operation modes (uni-direction and bi-direction), and passive filter (common mode filter and decoupling filter), are investigated and analyzed. The common mode equivalent circuit of the power converter is presented in this paper to explain the propagation path of the EMI between the inverter and rectifier. The field measured results are presented to clearly show the EMI performances of the commercial power converters.

The Smart Transformer (ST) is a solid-state transformer with control and communication functionalities, interfacing medium voltage and low voltage (LV) grids. The ST-fed grid has high potential to optimize power system and avoid or postpone the reinforcement of distribution networks. However, with the increasing utilization of power converters, the challenges in terms of system stability are encountered. To better understand the problems, this paper firstly develops the models of ST LV converter and grid-forming as well as grid-following converters used in the LV grid. Then, the stability of a ST-fed grid with different types of converters is studied by considering the effect of line impedance. To address the stability issues, a robust control strategy is proposed for the ST LV converter. Simulation results are provided to validate the effectiveness of the proposed control scheme.

This study proposes the voltage control strategy for distributed energy resource (DER) in islanded AC microgrids (MG). Typically, AC MG can maintain a constant voltage at the point of common coupling (PCC) as well as perform power-sharing among the DERs. However, linear controllers have several restrictions such as slow transient response, poor disturbance rejection capability etc. Therefore, this study presents an FCS-MPC for a DER with effective voltage regulation capability. The investigated work demonstrates excellent steady-state performance, a low computational burden, better response under transients and have low switching frequency as compared to linear control. First, the benefits of FCS-MPVC for single DER has been studied, then the same topology along with droop control is employed for multiple DERs in AC MG to serve the load. Droop control shows improved power-sharing among the DERs. The performance of the proposed control technique is demonstrated through MATLAB/Simulink simulations for single DG and AC MG under linear, non-linear loading conditions.

An extended use of renewable energies and a trend towards increasing energy consumption lead to challenges such as temporal and spatial decoupling of energy generation and consumption. This work evaluates the possible applications and advantages of hybrid energy storage systems compared to conventional, single energy storage applications. In a mathematical approach, evaluation criteria such as frequency, probability of power transients, as well as absolute power peaks are combined to identify suitable thresholds for energy management systems on a multi-timescale basis. With experimental load profiles from a municipal application, an airport, and an industrial application, four categories, clustering similar roles of the VRFB and the SC, are developed.

The use of renewable sources has attracted large interest in the area of electricity due to environmental issues that have affected the Earth. Brazil has great potential for solar electricity generation, which has been used by some public and private institutions. In this context, the inclusion of photovoltaic energy as an alternative source in the Brazilian mix has gained considerable prominence in recent years. The main purpose of this work is to present studies that aim at providing high power for an isolated load, through the application of a photovoltaic (PV) system connected to an inverter based on the three-state switching cell (typical acronym: 3SSC). This case shows itself as an interesting alternative because of the advantage of reducing the current levels of semiconductor devices by using a mixed multi-port PS-PWM, phase shift and delta-sine modulation control technique. The proposed system will be implemented in the PSIM software and the results and specifications will be discussed throughout next sections. Furthermore, there is a brief evaluation concerning ongrid operation, also considering the implementation of a cascaded boost converter (with Maximum Power Point Tracking - MPPT) to the above mentioned 3SSC inverter.
