This paper introduces the use of Monte Carlo simulations (MCSs) for modeling stochastic behavior of wind speed, irradiance, temperature, load and electricity rate (ER) as well as the availability of PEV. Two methods are introduced. Probability distributions and their parameters are described in the first method which can be use in the future researches. Second method is introduced for MCS to consider the correlation between different databases and the correlation of each interval value with their prior interval value. Recommendations are provided for the first method in the future studies.

The technological innovation of systems in tunnels allows to reach high levels not only in energy efficiency but also in safety, where the legislation requires safety measures based on systematic considerations of all aspects of the system (infrastructure, operations, users, vehicles).In many existent tunnels, some structural safety measures could be implemented only through technical solutions with a disproportionate cost because of difficulties due to old infrastructures, unfavorable orographic situation or tunnels in sequence in wich simultaneously road works could cause a paralysis of traffic with unbearable economic and social costs. Therefore, a new layout of the SCADA system, able to perform a Dynamic Risk Analysis (DRA), has been developed to achieve immediate and effective benefits through the implementation of operational measures in Smart Tunnels in which advanced systems and sensors are installed. DRA can be associated with Energy Management Analysis (EMA) in order to perfectly fits within the "Industry 4.0" new European approach: through low costs it is possible to know real time what happens inside the tunnel, the environmental conditions, traffic data and system status (Smart Production), to apply operational measures in order to ensure the safety required (Smart Services) and to operate in energy saving mode whenever possible (Smart Energy).

The time-domain calculation of electromagnetic transients in multi-conductor lossy overhead lines and buried cables requires the evaluation of the transient ground resistance matrix. For the case of overhead lines, analytical expressions for the transient ground resistance obtained by solving the inverse Laplace transform of Sunde’s formula have been recently presented. This paper presents the expressions obtained by the analytical inverse Laplace transform of Sunde’s formula for the case of buried cables. The results provided by the proposed analytical expressions agree with those given by the numerical inverse transform of Sunde’s formula. The new expressions are adopted for the calculation of the per-unit-length voltage drop in a multiconductor underground line. The voltage drop waveforms are compared with those given by recently proposed time-domain analytical expressions that neglect displacement currents.

This paper presents a service that allows an operational assessment of solar energy systems based on the prediction of climate variables on different time scales, daily, monthly, seasonal or annual. The service is a planning tool building upon the Copernicus Climate Change Services, together with solar models and spatial and operational data of photovoltaic facilities. The added value of this service, as opposed to other systems that can be found on the market, is that it has been developed through an effective co-design with end-users, contributing to mutually beneficial collaboration, making possible to sustain their marketability and value. The proposed service is introduced and tested for automating both spatial and operational assessment of a utility-scale photovoltaic (PV) power plant. Experimental results are presented, which show and address the performance of the entire service.

Recent innovations in Information Technology, Cloud Computing, Big Data analysis, Internet of Things (IoT) and Artificial Intelligence (AI) are enabling technological solutions that were previously unimaginable, or usually available only for big IT companies, with impacts in both industry and services. The demonstrator named Smart Grid Semantic Platform (SGSP) has been created using these technologies integrating several aspects of the management of an electricity distribution network. The services deployed on the platform concern the visualization of the topographic data and electricity grid assets, as well as the processing and displaying of historical data related to the operation of the networks and/or the result of Big Data analysis. This paper demonstrates how useful the synergy is between the standard semantic model of the electric network (IEC CIM 61968) and the historical data of the time series of medium voltage electricity consumption analyzed using a Big Data platform. Specifically it illustrates the realization of a use case about the calculation of a load index of the electric lines.

This work presents a hammerstein adaptive filter based technique for power quality improvement of a three phase grid tied two stage solar photovoltaic system. This system provides the PV power to connected load and surplus energy to the utility. The key objective of this work, is to extract positive sequence components (PSCs) from distorted grid voltages for estimation of unit templates and proposed control extracts load current fundamental component. A feed-forward term for PV source is also introduced for enhanced dynamic response of the system. This system is examined for the conditions of unbalanced load, voltage distortions, voltage swell/sag and variable PV irradiation to prove the efficacy of the control algorithm. The system performance is acceptable and grid currents THD’s are in limits, as suggested by the IEEE-519 standard.

In this paper, a new method for optimal sizing of distributed generation (DG) is presented in order to minimize electricity costs in smart microgrids (MGs). This paper presents a study of the effect of wholesale electricity market on smart MGs. The study was performed for the Ekbatan residential complex which includes three smart MGs considering high penetration of renewable energy resources and a 63/20 kV substation in Tehran, Iran. The role of these smart MGs in the pool electricity market is a price maker, and a game-theoretical (GT) model is applied for their bidding strategies. The objective cost function considers different cost parameters in smart MGs, which are optimized using particle swarm optimization (PSO). The results show that applying this method is effective for economic sizing of DGs.

Visual adaptation demands increased illuminance in the tunnel entrance, which results in an increased number of installed luminaires and power consumption of each luminaire. There are norms that define the required luminance in this entrance zone, which depends on the variability of the daylight on the surfaces that surround the entrance. In most existing tunnels, at the time of their design, there were no proper simulation tools resulting in an over-dimensioned lighting system, thus leading to over illumination and increased energy consumption. The reduction of this consumption can be realized through proper optimization of the pavement or by retrofitting the lighting system with cost effective LED luminaires. However, energy savings can be achieved with proper control of the tunnel’s lighting system, since it is quite common to be organized in a number of active stages. In this paper, a non-cost fine-tuning method for switching the lighting stages according to the traffic weighted L20 luminance is proposed. The method was applied in a real –case scenario, where L20 luminance of the access zone at an existing tunnel was newly calculated. A new luminance demand value for threshold zone was calculated using the traffic weighted L20 method of CR14380. The new transition zone decreasing luminance curves were produced and compared with the existing ones. Thus, a new switching control was proposed and programed to the Supervisory Control and Data Acquisition system of the tunnel. The signal of the L20 meter for a period of two days was used and the corresponding energy consumption was calculated using the proposed switching program. The results have been compared also with a scenario were the existing lighting system was retrofitted with LED luminaires. The fine-tuning method for switching resulted in 26% and 35% energy savings concerning the existed installation with no extra cost while the energy savings by installing LED was 52% and 69% with an additional cost of LED luminaires and the corresponding labor cost for the retrofit.

In this paper, an uninterrupted power supply (UPS) and an isolated three-port bidirectional converter (TPBC) are developed by connecting a three-phase voltage source converter(VSC), a battery energy- storage system (BESS) and a grid-connected boost converter-fed three-phase DC/AC converter through a single three-winding isolation transformer(Tr). This design presents features that are suitable for multiple voltage electrical systems. The three-port power exchange is multi-directional which can be delivered either separately or simultaneously. In consideration of the safety requirements, electrical isolation is achieved between any of the two ports. Besides the power-flow concept, different operating principle stages, power flow equations, small signal model, network simulation model, and control strategy are discussed. Furthermore, the steady-state analysis are evaluated to determine the power flow equations. The control strategy proposed is based on single-phase shift control, with the small signal model for optimized controller design, which can predict the accurate frequency response and obtain a fast dynamic response. Meanwhile, this can be used in many applications of electronic power converters. The simulation results have been provided under various operating conditions, which confirms the effectiveness of the proposed control strategy. The result showed that the power management feature of the system was successful and waveforms are obtained. Finally, theoretical considerations and simulation results for different operating stages are verified by MATLAB / SIMULINK

The continuous growing in environment requirements combined with the proximity of ports to city centers make it necessary to take actions in favor of the site decarbonization. Therefore the electrical distribution grid of port needs to be analyzed and renewed for reducing the CO2 equivalent mass produced. This goal can be reached by using an integrated monitor systems in order to impose a desired power-flow and proper voltages on the different grid nodes. Not only the possibility of supervising the grid but also some notable functionalities are enabled by these innovative systems: for example cold ironing hubs, electrical vehicle recharge hubs, optimization of power generation and storage functionality. In this paper, the Port of Trieste is taken as case of study and possible evolution scenarios will be presented using a mathematical model of the medium voltage power system. Particularly, an innovative real-time hierarchical monitor system architecture will be discussed, while a patched Linux PC will be presented as possible monitor device implementation.
