This paper presents the mathematical formulation for the modelling of Power-to-gas devices that has been included in the existing medium term Power System simulator sMTSIM. This is the first step towards the implementation of a linear mathematical model capable to describe the integrated Electricity and Gas Systems. Such kind of tools is fundamental to perform scenario analyses on the future Energy Systems: the path to a completely decarbonized world, in fact, passes through the use of low carbon syngas, produced by Power-to-gas devices. Such devices, consuming electricity to produce syngas, are also useful to reduce the impacts of a large installation of non-programmable Renewable Energy Sources on the Power System. A case study based on a 2050 scenario of the Italian Power System and characterized by a very high share of non-programmable RES generation is also presented to test the upgraded version of sMTSIM.

IEC 60870-5-104 is a widely used protocol in power telecontrol applications and, due to its relative simplicity and interoperability with legacy architectures, its usage is also considered for future control functions managing flexible energy resources. The security mechanisms of IEC 62351 standard can be applied to application and transport layers of IEC 60870-5-104 communications in order to mitigate threats to cybersecurity. In a laboratory environment a scenario has been simulated where the main functions of monitoring and control communications for flexibility management use cases have been implemented and analyzed. Key performance indicators have been identified to support the performance evaluation of the security configurations defined in IEC 62351. A methodology for measuring the indicators has been defined and implemented. Finally, the cybersecurity impact on the performance of communications as a function of the configuration parameters defined in the standard are reported and analyzed.

Recent technological advances made possible the development of devices and integrated circuits operating at frequencies greater than 100 GHz and telco operators, in order to face with the growing demand for bandwidth from users, are increasingly turning their interest to the feasibility of use wireless links also at sub-millimeter frequencies (300 GHz–l THz). This spectral region, also named TeraHertz band, offers greater availability of contiguous bands and is under investigation by international standardization bodies such as ITU and CEPT. The present study intends to provide useful insights to define technical and operational characteristics for 5G applications aimed at land-based fixed services operating in bands up to 1 THz. In this study simulations was carried out to provide an estimation of attenuation levels due to the gaseous component, precipitating events present in the troposphere at the ground level. Furthermore, radio refractivity was also estimated. All results are referred to the Italian territory and for frequencies ranging from 40 to 840 GHz.

In this work, a method based on Deep Learning algorithms is applied to assess the validity of voltage dips. The aim is to clean voltage dips statistics from voltage drops due to the measurement transformers saturation, by analyzing their waveforms. In the proposed solution, the signal processing problem addressed is transformed in an image recognition task. The algorithm adopted is based on a convolutional neural network properly trained on a set of images, extracted from the voltage waveforms monitored in the distribution network by the Italian research monitoring system, QuEEN, managed by RSE. The algorithm answer is Boolean: true or false voltage dip, tertium non datur. The obtained results are compared with those usually achieved by a different criterion, based on the detection of a second harmonic component in the measured voltages, already active in both the QuEEN and the Italian national monitoring system. The performances of the two methods in detecting real events with overlapping saturation are compared referring, in particular, to those events for which the traditional method cannot provide an answer (undefined cases). Their pros and cons are then discussed.

The energy transition is changing the electrical power system. The increasing number of distributed energy resources in the distribution system and the digitalisation of most of the sensors and actuators are bringing the electrical grid to became a Smart Grid. Component and system testing for Smart Grid topics can introduce many challenges. ERIGrid Project tried to Figure out some of the upcoming issues investigating the possibility to expand Smart Grids laboratories potentialities and capabilities by means of research institutes cooperation and Research Infrastructures integration. Different tools for laboratory integration have been developed in the project. Among them a new methodology, called Holistic Test Description, has been developed with the goal to help researchers to clearly identify the test scope and the best test procedure to be adopted. Moreover a new communication tool, called JaNDER, has been developed by Ricerca sul Sistema Energetico (RSE) which is also member of the consortium of ERIGrid Project. This tool allows real time data communication between Research Infrastructures in an easy and effective way enabling a virtual connection between laboratories. These tools have been successfully tested and proved in the Distributed Energy Resources Test Facility (DER-TF) of RSE both by RSE researchers and also external users demonstrating the possibility to largely extend Smart Grid laboratories experimental potentialities. This paper shows some of the developed tools and presents some tests performed in RSE DER-TF that demonstrate how laboratories integration can reduce test set-up timing, optimise laboratory usage and improve the quality of experimental testing activities.

Conventional LCC HVDC system is unable to provide dynamic reactive power and AC voltage support to power system during transient events. This can have adverse impacts on the renewable generation that is connected to the same power system such as wind farms. This paper aims to demonstrate that the Flexible LCC HVDC system can provide dynamic reactive power and AC voltage support to a wind integrated power system. The Flexible LCC HVDC system is able to quickly inject reactive power into the system, reducing the voltage drop and increasing the speed of voltage recovery. This will help the wind farms in riding through the fault. At the same time, due to the elimination of Commutation Failure (CF) in the Flexible LCC HVDC system, it is able to maintain a relatively stable active power transfer as well. Simulation comparisons between the conventional LCC HVDC and the Flexible LCC HVDC based on a wind integrated two area power system have been presented to validate the performance.

Nowadays, the Integrated Power and Energy System (IPES) is no more a marginal part of the ship and the electrical equipment arrangement is becoming increasingly difficult. Indeed, an all-electric cruise ship has 65 km of cable trays and more than 4000 km of power cables to supply all the shipboard electric loads. In this scenario, the cable layout in the cable tray is not considered during the early stage design phase. Nevertheless, different cable arrangements can have undesired effects on the power line parameters. Thus, in this paper a Python code is compared to two different Finite Element Method (FEM) software to assess its effectiveness in calculating the inductance matrix considering the power line arrangement in the cable tray. Secondly, two methods are used to determine the equivalent inductance and evaluate its dependence over the cable layout. It is shown that the effect of cable arrangement in the cable tray on the power line equivalent inductance is not negligible and it should be taken into account in the early stage design phase.

In the framework of energy transition, targets of power system adequacy point out the necessity of specific mechanisms for individuation and remuneration of sources of flexibility. In this outline, the Italian energy market has recently been integrated by a capacity market platform, based on reliability options for expected generation availability at peak, where the demand curve reflects target levels of loss of load expectation. In this paper, a model of Italian capacity market is introduced, whose solution process is based on sequential process of zonal equilibrium. Criticality of data collection for the determination of demand curve, possible capacity bids and zonal interactions are discussed. With the aim of investigating the impact on market solutions and on selected technologies, sensitivity analysis on different factors is carried out.

The Italian demo of the H2020 Osmose project, which stands for Optimal System-Mix Of flexibility Solutions for European electricity, is led by Terna and aims at developing a novel Energy Management System (EMS), which allows managing distributed Renewable Energy Sources (RES) and severe grid congestions. This is obtained by properly coordinating innovative flexibility resources which include Dynamic Thermal Rating (DTR) and Demand Side Response (DSR). The DTR methods proposed under this framework have been developed by Ensiel, a consortium of Italian universities active in power systems research. These solutions include a sensor-based method, based on a self-organizing sensor network composed by cooperative smart nodes deployed along the line route, and a weather-based technique, based on a thermo-mechanical model of the monitored line. The main features of these advanced solutions are described in this paper, and the first experimental results obtained on real case studies are presented and discussed in order to prove their effectiveness.

The main features of these advanced solutions are described in this paper, and the first experimental results obtained on real case studies are presented and discussed in order to prove their effectiveness.","PeriodicalId":6689,"journal":{"name":"2020 AEIT International Annual Conference (AEIT)","volume":"53 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88249299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
