Abstract:

In railway signaling, operational scenarios are integral to the system modeling process, serving to outline expected use cases and define the behavior of the system, subsystems, and actors within the railway environment. Operational scenarios are a primary source of requirements for developing the train control system and its subsystems. Additionally, the design of operational scenarios can offer invaluable insights for arranging trackside assets and may influence the creation of instructions and operational procedures for railway staff.

Abstract:

The Spanish port system is subjected to a Data Envelopment Analysis (DEA)-Bootstrapping analysis of its operational and financial efficiency to be compared to two other scenarios. One of these presents a port cluster based on the grouping of ports because of their proximity, and the second scenario proposes a port cluster based on seafronts. The analysis is made up of a DEA-Bootstrapping of two inputs and two outputs for both the operational and financial efficiency analyses. The results of the DEA-Bootstrapping analysis show a series of results that favour these two scenarios against the pres

During mission design, the concept of operations (ConOps) describes how the system operates during various life cycle phases to meet stakeholder expectations.

This approach is robust when designing an automated system or a system with a low level of autonomy.

As scenario generation routines often are probabilistic, for example based on sampling, it is crucial that they ensure stable results in the capacity expansion model, so that it is the underlying uncertainty that decides the optimal solution, and not the approximation of that uncertainty in the model. However, it is unclear which operational scenario properties that are important to ensure good results an

Various modelling approaches already exist and in this original paper, four models representing these approaches are compared in two real-world hybrid energy system scenarios. The models, namely TransiEnt, µGRiDS, and OpSim (including pandaprosumer and mosaic) are classified into component-oriented or system-oriented approaches as deduced from the literature research. The methodology section describes their differences under stan

Abstract:

In this paper, we propose a method for the generation of simulated test scenarios for autonomous driving. Based on the requirements of standard regulatory test scenarios, we can generate virtually simulated scenarios and functional scenario libraries for autonomous driving, which can be used for the simulated verification of different ADAS functions. Firstly, the operational design domain (ODD) of a functional scenario is selected, and the weight values of the ODD elements are calculated. Then, a combination test algorithm based on parameter weights is improved to generate virtually simulated

Abstract:

This study examines the integration of wind power plants and the application of Emergency Demand Response (EDRP) in the Unit Commitment (UC) problem in the electric power system, by utilizing the Binary Particle Swarm Optimization (BPSO) method. The UC problem focuses on optimal scheduling of generating units to meet load requirements with minimum operating costs. However, the intermittent characteristics of wind energy cause significant uncertainty in the scheduling process. Therefore, EDRP is applied as an adaptive strategy to change the load demand pattern dynamically, so as to improve syst

Abstract. A model-based tsunami prediction system has been developed as part of the French Tsunami Warning Center (operational since 1 July 2012). It involves a precomputed unit source functions database (i.e., a number of tsunami model runs that are calculated ahead of time and stored). For the Mediterranean basin, the faults of the unit functions are placed adjacent to each other, following the discretization of the main seismogenic faults. An automated composite scenarios calculation tool is implemented to allow the simulation of any tsunami propagation scenario (i.e., of any seismic moment

Abstract To improve the stability and economy of power system operation under the deep penetration of renewable energy, a trilevel adaptive robust optimization model is proposed for the self-scheduling of the multi-energy virtual power plant, which is solved by the column-and-constraint generation algorithm.

With the gradual maturity of the automatic train operation (ATO) system in subways, its application scope has also expanded to the high-speed railway field. Considering that the ATO system is still in the early stages of operation, it will take time to fully mature, and definite specifications of the requirements for system operation have not yet been formed. This paper presents the operational design domain (ODD) of the high-speed railway ATO system and proposes a scenario analysis method based on the operational design domain to obtain the input conditions of the system requirements.

The increased complexity of the transmission grid can endanger the operational security of the grid. Operational risk assessment, a stochastic tool, helps to enhance security. Contingency analysis and its impact quantification are the main constituents of operational risk assessment. In this study, different graphical methods are proposed to visualize operational risk contingency-based detailed results: heat-map and risk-based contingency chart. Through the heat-map, the system operator can determine which contingencies contribute most to the operational risk and would therefore be the most th
