This paper designs a hierarchical control system to improve control performance in a multi-terminal high voltage direct current based on the voltage source converter (VSC-MTDC) transmission system. In this control scheme, the primary control layer employs droop control, while the secondary control layer has developed optimal power flow control (OPF) for maintaining the variation of DC voltage and regulating the active power, and simultaneously minimizing power loss. In the event of a power disturbance or a change in power generation or consumption in the DC system, based on OPF results a new stable droop operating mode is established to stabilize DC voltage variation and regulate active power in the network. A ±400 kV four-terminal VSC-MTDC test network has been developed by using PSCAD and MATLAB simulation tools to assess the proposed control scheme. The primary controller is designed in PSCAD, and the secondary optimum control technique is applied in MATLAB. The results of steady-state and transient operating modes demonstrate that the planned control technique can achieve DC voltage regulation and keep active power, and minimize the power losses in the MTDC system. © 2022 IEEE.

With the widespread application of sensors nodes in power equipment, providing a stable energy supply for these sensors has become a significant challenge. Traditional batterypowered solutions are costly and difficult to install. The development of energy harvesting technology offers a new technical approach to address this challenge. This paper mainly investigates how to enhance the energy harvesting power of Magnetic Field Energy Harvesters (MEH) under conditions where the magnetic field around power equipment is limited. A dynamic control method is proposed to improve the energy harvesting power of MEH. The fundamental idea of dynamic control is to precisely control the MOSFETs in the rectifier, dynamically adjusting the switching times of the energy harvesting interval to be symmetric around the peak current of the primary side, thereby significantly enhancing harvesting efficiency. This method is particularly applicable when the magnetic core enters the soft saturation region, causing the energy harvesting interval to be less than T/2. Experimental results show that under constant voltage load, dynamic control effectively adjusts the energy harvesting interval, maximizing the current extracted during this interval, thereby effectively increasing energy harvesting power. Compared to passive rectification, active rectification under dynamic control increases the energy harvesting power by 76%, and the power factor of active rectification is 1.7 times that of passive rectification. The research findings provide important theoretical support and practical significance for the application of magnetic field energy harvesting technology in sensor nodes.

Currently, a large number of community integrated energy systems operate independently and lack coordination and cooperation with each other. On the whole, the complementary coupling potential between energy production and consumption has not been fully explored, which is not conducive to the efficient utilization of clean energy. To solve the above problem, this paper proposes an optimal scheduling model of community integrated energy system considering integrated demand response and carbon tax. Moreover, based on cooperative game theory, this paper adopts the Sharpley value to achieve fair and reasonable distribution of cooperation profits. The case study results indicate that the energy sharing model proposed in this article can achieve better economic benefits.

Robust optimization approach (ROA) is conservative in tackling the uncertainty of renewable energy (RE) in unit commitment (UC). To deal with this problem of ROA, adjustable uncertainty set (AUS) is proposed and it is a subset of the maximum uncertainty set of RE. However, there exists operational risk of load shedding and RE curtailment in the scenarios where the generation of RE exceeds the AUS. In this paper, demand response (DR) is scheduled to determine the AUS. It reduces the conservativeness of ROA and meanwhile guarantees there is no operational risk. The safe operation of UC is guaranteed in the AUS and DR is used to compensate the RE’s uncertainty when RE is out of the AUS. Through the introduction of the auxiliary constraints and variables, the original UC problem formulation is transformed to a mixed integer linear programming problem and solved by commercial solvers. The proposed method proves effective in IEEE 6-bus and 118-bus systems. Simulation results show that the proposed method reduces the operational cost of UC, and its effectiveness is improved with more participation of DR.

With the extensive utilization of Intelligence Electronic Devices (IED), the modern smart substation is regard of a typical Internet of Things (IoT) system. The process-layer network in smart substations, which carries the measurements and control signals, needs to operate reliably in the face of unforeseen failures and external malicious attacks. In this paper: i) a mathematical framework for the process-layer network, attacks, and signals is modeled;ii) fundamental network performance limitations from system-theoretic and graph-theoretic perspectives are characterized;and iii) A DLL-based Router Scheme (DRS) is designed to ensure the network performance for the effective operation of IoT. Finally, we validate our design through a series of cases, and the results show that the designed DRS is effective to smooth the network performance. © 2022 IEEE.

With the inertia improvement ability, Grid-forming Converter (GFC) can be implemented in large-scale power system to improve instability issues. Although with these advantages, increasing connections of the distributed renewable resource also gives a chance of attack which can be accomplished via supervisory control and data acquisition system by controlling their converters in remote/physical ways. Thus, the objective of this paper is to solve the False Data Injection Attack (FDIA) instability of the GFC renewable integrated system which is barely studied in these years. The mechanism of the adverse effect of attacks on GFC is analyzed by combining its small signal model with the FDIA model. In advance, a novel control strategy considering the power system’s spatial structural features and temporal consistency is proposed to defend against FDIA based on dynamic state estimation. Meanwhile, the adaptive adjustment factor and singular value decomposition are introduced into an improved cubature Kalman filter to deal with the data mutation and matrix error caused by attacks. The simulation on IEEE 30-bus system and full real-time experiment on RT-LAB verification test platform are carried out, and the results show that the proposed voltage control strategy has a superior performance to mitigate the impact of FDIA. © 2023, The Authors.

To realize the economic optimization dispatch of PSMG (Photovoltaic Storage Micro-grid), considering the stochastic influence of multiple uncertainties, this study formulates a day-ahead optimal dispatching strategy of PSMG with the minimum comprehensive operating cost as the objective function. Firstly, the source-load uncertainty is dealt with by scenario generation using the Monte Carlo method and k-means clustering algorithm. Then the peak shaving ability of the system is enhanced by the introduction of flexible loads, and the scheduling flexibility of the photovoltaic storage system is increased by the integrated demand response increases the scheduling flexibility of the photovoltaic storage system. Finally, simulation results show that the scheduling scheme can prompt the source-load to participate in peak shaving and valley filling at the same time, increase the new energy consumption capacity of the photovoltaic storage micro-grid, and effectively improve the economic and social benefits of the micro-grid.

The Qinghai-Tibet Plateau contains the most abundant clean energy such as hydropower, wind and solar in the world. However, it is very difficult to add overhead transmission lines on the ground due to the complex geographical environment. The large-capacity tunnel cables which is less affected by the earth surface environment, may play an important role on the energy transmission in such area. Based on the cable thermal circuit model, the electrical-magnetic-thermal multiphysics coupling of the cable is modeled in COMSOL Multiphysics. The parameter changes of the material during the temperature rising process, the influence of different ventilation conditions and different current-carrying capacities on the changes of the cable temperature field are quantitatively analyzed. The results show that the proposed model is valid in certain conditions. The research on the current carrying capacity and thermal effect of tunnel cables is of great significance for the transportation and consumption of large-scale clean energy resources.

To realize the dual carbon policy, the goal of energy saving, and emission reduction, it is important to develop ways to better promote the low carbon economic operation of energy systems. Therefore, this research proposes an optimal operation strategy considering the electric-gas-cooling-heat demand response. Considering the demand response of each participant, an integrated energy system model with photovoltaic, wind energy, and traditional grid as energy supply. Also, electric energy, natural gas, cooling, and heating subsystems with co-production are established. With minimizing the overall system operation cost and optimizing environmental protection, the improved particle swarm optimization algorithm is used to solve the multi-constrained objective optimization problem. Finally, the optimized model is tested. The results from this study show that the energy system under cogeneration can find a balance between economy and environmental friendliness, and provide a reference for the subsequent energy supply configuration. © 2022 IEEE.

To achieve the economic operation of a multi-energy micro grid under multiple uncertain environments, this study introduces a novel two-stage robust scheduling approach, encompassing both day-ahead planning and real-time adjustments. First, the multi-energy micro grid day-ahead economic dispatch model is constructed based on the prediction scenarios, and integrated demand response is considered to increase the flexibility of the system. Afterwards, the strategy is adjusted in the real-time phase, considering the uncertainty of energy production and consumption. The Column-and-Constraint Generation algorithm is employed to resolve the above two-stage issues effectively, and the optimal economic operation strategy of the MEMG is obtained. Finally, a case study demonstrates the economy and robustness of the proposed methodology.
