Renewable Sources and Energy Storage Optimization to Minimize the Global Costs of Railways

Climate change is one of the biggest global issues for humanity these days, and its effect has become more severe. The transport sector accounts for around 30% of greenhouse gas emissions, which need to be decarbonized urgently. Railway electrification is one of the low-carbon solutions, but it still relies on power grids causing carbon emissions. To further decarbonize electric railways, the renewable energy sources (RESs) and energy storage system (ESS) integration scheme for railway traction power network has been proposed. This paper developed the energy management system to calculate the energy flow and global cost. Moreover, contact wire loss and conversion loss were considered. The optimization problem to find the optimal capacity and location of the PV farm, wind farm and energy storage system to achieve the lowest global daily costs was solved by the Brute Force Algorithm. The traction network of the High Speed 2 Railway in the UK has been taken as a case study. Results revealed that the global cost and carbon emissions are reduced considerably with both ESS and RESs installed. In the scenario of the ESS alone, 1.3% of the global cost is saved by capturing the regenerative energy and reusing it. Furthermore, this figure goes up to 10% and 62% when the PV and wind farms are integrated, respectively. When considering all variables, it is found that installing the wind farm is a more economical option than the PV farm. The study also shows that the optimal locations to install the plants and ESS vary by scenario.

Uniqueness of system integration scheme of artificial intelligence technology in fractional differential mathematical equation

Abstract In order to explore the fractional differential equations in accounting informatization financial software, the author proposes a system for fractional diffusion wave equations and fractional differential equations, two numerical algorithms with higher precision are given, and the amount of computation is reduced at the same time. First, based on the equivalent integral form of the time fractional diffusion wave equation, using the fractional echelon method and the Crank-Nicolson method, for the time fractional diffusion wave equation, a finite difference scheme is designed, this format has second-order accuracy in both the temporal and spatial directions and is computationally stable. Numerical examples verify the accuracy and effectiveness of this format. Then when dealing with the initial value problem of fractional differential equations with Caputo derivative operator, convert it to the equivalent Voltera integral equation system, an initial approximate solution is obtained by a low-order method, derive the residual and error equations, the idea of applying the stepwise correction of spectral delay correction improves the numerical accuracy of the solution, at the same time, the Richard Askey integral equation is used to reduce the amount of calculation. At last, the high precision and effectiveness of the new method are verified by numerical experiments. Experiments show that: Starting from the equivalent integral form of the fractional diffusion wave equation, a second-order finite-difference scheme of the fractional-order diffusive wave equation is constructed, through numerical experiments, it is verified that the scheme has good accuracy and efficiency. In numerical solution, discrete integral equations have better numerical stability than differential equations, therefore, the format also has better stability. When taking different fractional derivative indices a=1.5 and a=1.8, it can be seen that the difference format constructed by the author, in the time direction, has second-order precision, as expected.

Uniqueness of system integration scheme of artificial intelligence technology in fractional differential mathematical equation

Abstract At present, various branches of mathematics have developed very mature, but they still lack an internal structural correlation. They are like “islands” in the universe. If we can find the universal conversion relationship of the three basic mathematical structures of geometry, arithmetic and logic, it will greatly expand the field of mathematics. The ultimate goal of mathematics in the past is to pursue its preciseness, while the ultimate goal of mathematics in the future is to pursue its unity. Fractional differential equation is a generalization of integer order calculus. It discusses the theory of any non integer order differential and integral equation. The rise of artificial intelligence technology just provides the most powerful laboratory for the unity of mathematics. To explore the mystery of the brain and achieve the ultimate goal of artificial intelligence technology, the key is to make a major breakthrough in basic mathematical research and find a basic theoretical system describing the mutual mapping and transformation of different mathematical paradigms. The unity of mathematics will undoubtedly become the forefront of the development of mathematics in the future, which will be the core of the research on the new generation of intelligent computer and artificial intelligence technology.

Design of Distribution Automation Master Station System Integration Scheme Based on “n + 1” Architecture

More and more network and provincial companies within the State Grid have adopted the “n + 1” architecture, that is, the deployment of production control at the regional and municipal levels, and the centralized deployment of information management at the provincial level to build the distribution automation master station system. The main station system of information management regional can independently evolve into the distribution cloud main station. In response to the construction trend of “n + 1” architecture, an integrated scheme’ of distribution automation master station system based on “n + 1” mode is proposed, and it is verified and analyzed on the new generation of distribution master station system constructed by State Grid Ningxia Electric Power Company.

At the same time, this construction mode can reduce operating costs, improve the efficiency of distribution network data utilization. At present, this scheme has been applied in Sichuan, Inner Mongolia, Jiangsu and Shanghai Electric Power Company, has a strong demonstration.

Optimal design for double reheat coal-fired power plants with post-combustion CO2 capture: A novel thermal system integration with a carbon capture turbine

The development of post-combustion capture is greatly restricted by its high energy consumption and the thermal efficiency penalty resulting from absorbent regeneration. This study provides novel insights into the design of a thermal system for double reheat coal-fired power plants integrated with full-scale post-combustion CO2 capture. To this end, this study proposed a modified thermal system integration scheme that included an extraction backpressure turbine called carbon capture turbine (CCT) to provide thermal energy for the regenerative heaters and CO2 capture system. A generalized thermal economy calculating framework and a thermal system parameter optimization model was also established to maximize the cycle thermal efficiency for the proposed scheme. A new unit was designed based on the modified scheme, and its parameters were determined by taking a 1000 MW double reheat coal-fired unit as a reference. These parameters were then optimized via dynamic adaptive particle swarm optimization. Compared with a conventional retrofitted unit, the coal consumption and CO2 emission rates of this newly designed unit were reduced by 0.01264 kg/(kW·h) and 0.00423 kg/(kW·h) after the parameter optimization, respectively. An exergy analysis for the proposed system shows that using CCT can efficiently prevent the extraction of steam superheat and the mismatch between the intermediate pressure cylinder exhaust and the reboiler from generating excessive exergy losses.

Radio frequency identification(RFID) is high technology, which can rapidly and real-timely acquisition information and accurately deal with information. And it has broad application prospects in retail, logistics, transport and other fields. Service oriented architecture(SOA) is a service-oriented architecture, which is used to design and realize the loose coupling software.

The SOA is used to realize the loose coupling and integration of RFID data event and application system, and deal with the configuration of the components. At the same time, .NET Remoting technology is used to realize the distribution architecture of middleware in order to ensure the deployment flexibility of middleware. The applied cases of a demonstrative application system, blood management and traceability system are used to illustrate its feasibility and effectiveness of the proposed integration scheme. The enterprise information system integration scheme provides an effective solution for system integration between different enterprises or internal enterprises. It can solve the compatibility between different application systems, and takes on the higher service efficiency, less CPU average occupation and better average response time. This study provides a stable and effective solution for information sharing between enterprises, improves the work efficiency and reduces the whole work management capital, and continuously improves the informatization level of the enterprises.

Robust wavelet-based inertial sensor error mitigation for tightly coupled GPS/BDS/INS integration during signal outages

This paper proposes a robust wavelet-based tightly coupled Global Positioning System (GPS)/ Beidou Navigation Satellite System (BDS)/Inertial Navigation System (INS) integration scheme aiming to improve the overall position accuracy during signal outages. A robust wavelet denoising model based on α-trimmed mean filter demonstrates its effectiveness on noise reduction and gross error elimination of inertial sensor raw data. Thereafter, a robust wavelet-based tightly coupled GPS/BDS/INS integration scheme is proposed, and GPS/BDS double-difference (DD) carrier-phase and pseudorange measurements are introduced to build a 27-state tightly coupled GPS/BDS/INS integration equation. The extended Kalman filter (EKF) has been designed for state estimation, and the inclusion of BDS enhances the satellite geometric strength of the whole navigation system. A field vehicle test indicates the position accuracy of five simulated GPS/BDS outages can be improved by about 7, 16, and 33% for north, east, and up components with the proposed scheme compared to standard integration scheme, and gross errors have been detected and eliminated with the new integration scheme. The authors also find that the BDS phase residual is larger than GPS and satellite dependent in the tightly coupled GPS/BDS/INS integrated navigation system.

System Integration of Electronic Functions in Smart Packaging Applications

A system integration scheme relevant for smart packaging applications is presented. Recent advances in printed electronics, radio frequency identification tag production, and standardization of communication protocols are factors that increase the design freedom for new applications. As in all new technology fields, the first products are expected to appear in the high-cost segment attracting early adopters in the form of niche products. A reasonable assumption is that these products will come from hybridization of different types of technologies. Such a scenario is likely since no technology solution available can provide all features that these types of applications demand. There is a need of standard solutions for hybridization of silicon devices and printed (or foil-type) components. Conductive ink technology is a powerful tool for hybridization and customization of large-area electronics, providing 3-D integration and large-area customization. However, high-performance communication and advanced processing demand the use of silicon. Smart hybridization solutions allow combination of the best from both worlds. This paper analyzes the requirements on hybridization technologies suitable for smart packaging applications and provides design examples on integration of intrusion surveillance solutions for cellulose-based packaging applications. It shows that even though the current hybridization technologies are far from optimal, they can provide a considerable design freedom and system performance.

Group preserving schemes for nonlinear dynamic system based on RKMK methods

In the present paper, the computation for the nonlinear dynamic system is discussed. Firstly the nonlinear dynamic system is converted into an augmented dynamic system in the Minkowski space, which results in the system of Lie type locally. Then Runge–Kutta Munthe-Kaas (RKMK) methods are used to the new augmented dynamic system and group-preserving integration scheme for the augmented dynamic system is constructed, in which the precise integration method is used to compute the exponential mapping. In the process of computation, the numerical schemes are formulated for nonlinear dynamic system directly. The advantages of the method presented in this paper lie in not only its group-preserving character but also in its simplicity.
