In Tactical situation display, lots of tactical information are expressed as symbols with an electronic map. There are various symbols depending on the situation throughout the mission (i.e., planning/operating/debriefing), and coordinate calculation is essential to display them in the appropriate location on the electronic map. Many tactical displays implement appropriate functionality to determine the location of each symbol, but they are affected by the performance of the computer processor. This proposal designs a method to decrease the overall display latency through fast positioning.

demosaicing and denoising of rAW images are crucial steps in the image signal processing pipeline of modern digital cameras. As only a third of the color information required to produce a digital image is captured by the camera sensor, the process of demosaicing is inherently ill-posed. The presence of noise further exacerbates this problem. Performing these two steps sequentially may distort the content of the captured rAW images and accumulate errors from one step to another. recent deep neural-network-based approaches have shown the effectiveness of joint demosaicing and denoising to mitigate such challenges. However, these methods typically require a large number of training samples and do not generalize well to different types and intensities of noise. In this paper, we propose a novel joint demosaicing and denoising method, dubbed Jdd-doubledIP, which operates directly on a single rAW image without requiring any training data. We validate the effectiveness of our method on two popular datasets—Kodak and McMaster—with various noises and noise intensities. The experimental results show that our method consistently outperforms other compared methods in terms of PSNr, SSIM, and qualitative visual perception.

Large scale renewable power plants (e.g., wind farms) are typically equipped with the cascaded H-bridge based Static Var Generator (SVG) for voltage regulation of the Point of Common Coupling (PCC). To enhance its capability in gridfriendly integration and operation of renewable power plants, this paper proposed an energy-type Static-var-generator (ESVG) with grid forming (GFM) control characteristics. First, the energy type SVG's converter typology is presented, then a new type of grid forming control utilizing the distributed energy of SVG's dc capacitor is proposed, having two main characteristics: 1) it achieves autonomous frequency response and grid voltage support similar to the majority of GFM controls;2) it has the self dc-voltage balancing capability, which does not require additional energy management control. The state-space model is also built to assess the small-signal stability of the ESVG system. Finally, an electromagnetic transient (EMT) simulation model of a typical grid-tied ESVG system is constructed in Matlab/Simulink, and simulation results show that the proposed control methods and associated characteristics are valid. © 2023 IEEE.

To achieve a sustainable low-carbon society and stable power supply to local areas, a self-sustaining distributed energy system' is proposed and evaluated. The system consists of multiple stand-alone small grids ('nanogrids') that utilize renewable energy sources and multiple electric vehicles (EVs) serving as power-interchange agents among nanogrids and as means of regional mobility. Two technologies required for constructing the system were developed. The first is 'nanogrid power-flow modeling' enabling quantitative evaluation including electricity loss in general nanogrid power systems including AC and dC nanogrids. The second is a 'powermanagement algorithm' for multiple-electric-vehicle operations using simulated annealing in which power consumption by moving EVs is considered. Also, a simulation environment that enables quantitative evaluation of the proposed system using regional demand data was built. The performance of the system, in the case that three nanogrids were installed in Iwamizawa city, Hokkaido, was evaluated by simulation. According to the results of the simulation (performed for 365 days), as compared to the electricity loss in the case of an AC system, that in the case of a dC system was reduced by 8%. Also, in the case of the dC system, the power supply from external power grids was reduced by 33% by increasing the number of EVs. These results suggest that the higher efficiency of the dC nanogrid system makes it more suitable for regional energy supply. © 2023 IEEE.

The increasing integration of renewable energy reduces the inertia and frequency support capacity of the power system. The issue of frequency stability has become one of the core issues in the security and stability of power system and the efficient consumption of renewable energy nowadays. To improve the performance of renewable energy power station (rEPS), based on the analysis of typical active support control logic and relative performance requirements of rEPS with single energy source (SES), an active support control strategy and coordinated control logic of active power of rEPS with multiple energy sources (MES) are proposed in this paper. The performance of proposed strategy is theoretically analyzed from the aspect of dominant energy source and the effect of the capacity of energy storage. The effectiveness of the proposed strategy and the accuracy of the theoretical analysis of performance are verified by realtime simulation. © 2023 IEEE.

With the construction of new power system, high-capacity renewable energy sources including wind power are integrated into the power system, whose transient response characteristics have a significant impact on the safe and stable operation of both renewable energy sources and power system. real-time simulation has become an effective method to study interaction between high-capacity renewable energy sources and power system because of its high accuracy and reliability, and precise wind turbine real-time simulation model is of great significance in research mentioned above. Therefore, the wind turbine control hardware in loop (CHIL) real-time simulation method is proposed in the paper, whose feasibility and accuracy are also verified by comparing simulation data from CHIL platform and on-site testing data. It's further used in the analysis of large-scale offshore wind farm cluster and connected power system as a practical reference case. © 2023 IEEE.

With the further development of "double high" characteristics of power system, the traditional stability problem dominated by synchronous generator has gradually evolved into a new stability problem dominated by power electronic equipment control. In addition, different types of failure problems can occur in wind power systems. In order to achieve multi-objective coordinated and stable operation of high proportion wind power system, a damping control method with parameters tuning is proposed, which includes the design of filtering link and proportional amplification link. Among them, the key parameters of the proportional link are adjusted. Finally, the feasibility of the proposed control method is verified by simulation tests. © Beijing Paike Culture Commu.
