This paper proposes a dynamic characterization of OLED aging process. The OLEDs are characterized by a very low dynamic resistance as well as a strong capacitive behavior. Moreover, the OLEDs are very sensitive to over-currents. Thus, the OLED control system should be precisely designed to drive the device. The aim of this study is to establish a dynamic electrical model illustrating the OLED characterization over time. This model is used to create a control system for OLEDs taking into account its characteristic deviation over time. In addition, the model is used to examine the control behavior using simulation, showing its behavior during both transient and steady-state. Furthermore, it is possible to predict the drift of the control system with aging. This ensures better performance for the OLEDs over its whole lifetime, which in return increases its lifetime. Moreover, the paper presents a methodology to predict the lifetime of the OLED just by measuring the voltage across the OLED at rated current. Finally, the proposed modeling is validated by studying the aging of a commercially available OLED.

The proposed study concerns the implementation of new strategies aimed at saving energy and reducing the global warming through the reduction of carbon emissions. For this purpose, the implementation of synergic procedures, contemporarily applied to microgrid and prosumers, are proposed and validated in the paper. The main implemented methodologies allow the real time management of different energy flows present inside buildings and, at the same time at higher hierarchic level, enable the supervision and control of the energy managed by the microgrid. The proposed general strategy optimizes contemporarily energy exchanges with the public electricity system, local electrical generation, storage and controllable loads. The developed concepts are valid in general, but also for the port systems where the purpose aims at saving energy and reducing CO2 emissions.

The present paper investigates the role of energy storage systems within microgrids characterized by the presence of power plants fed by renewable sources. In particular, the analysis is focused on microgrids where photovoltaic fields coupled with storage batteries are used to satisfy the energy loads of a well-defined area, such as a urban district or a campus. A linear programming mathematical model is proposed to daily manage the microgrid and, specifically, to determine the optimal charging and discharging of storage batteries in order to compensate the variability of loads and of the photovoltaic production. The reported case study is relative to a microgrid located in the North of Italy and the analysis of results refers to a period of one month. Different scenarios are described and the main advantages due to the installation of a storage system are highlighted.

Transmission system operators encounter new dimensions in their business operations in recent years. Huge sets of data are collected in control room and new functionalities are created for both real time and off line operations. Data from lighting detection system in control room will be used in a new way in next to real time manner. Transmission line outages caused by lightning strikes are recognized in precise manner and archived in real time. With detailed value of each lightning, it will be researched how much energy from the strike inflows to substation. Special security perimeter with three kilometers distance from substations will detect strikes. Those strikes, dangerous for equipment inside substation will be examined. Detail model of 110 kV line are modeled and various scenarios are conducted. This study work will give insights about amount of energy inflow to substation and give guidelines for making this process an automated procedure in the future. Results from this work will be used in maintenance business process in company.

As a consequence of the increasing renewable energy sources penetration, Transmission System Operators are facing critical stability challenges, e.g. lack of rotating inertia, frequency regulation and voltage control. In fact, majority of the recently installed renewable power plants are decoupled from the grid and are, therefore, unable to contribute to the grid stability in the case of network perturbations. In the world, wind energy represents one of the most interesting Renewable Energy Sources in terms of new installations. Two main categories of wind turbine exist: fixed speed and variable speed. In the second category, which is the market standard nowadays, Permanent Magnet Synchronous Generator and Doubly Fed Induction Generator are possible technologies. In particular, while the first one is fully decoupled from the grid, the second one is directly connected to the grid via the stator circuit and includes a power electronic converter to drive both magnitude and frequency of rotor currents. Differently from a fixed speed wind generator, the power converter enables the wind turbine to regulate the output power over a wide range of wind speeds to maximize the wind-to-electricity conversion efficiency. With the aim of preserving grid stability, recently connected wind turbines are required to contribute in the frequency and voltage regulation. In detail, the recently applied Italian connection standard for new type D wind power plants (i.e. rated power higher than 10 MW) imposes controllers for providing frequency and voltage support. The paper discusses the positive role that wind generators could have in terms of network stability if recent standards are correctly applied, making use of suitable simulations realized in the DIgSILENT PowerFactory environment. Doubly Fed Induction Generators have been considered, since this technology is currently the most widely used.

This paper proposes an adaptive DC link voltage based bi-directional electric vehicle (EV) charger, which operates in all the four quadrants of P-Q (active-reactive powers) plane. The four quadrants operation of charger enables the, only active (charging/discharging), only reactive (inductive/capacitive) and simultaneous active (charging/discharging) and reactive power (inductive /capacitive) exchange with the grid. This paper also proposes an adaptive DC link voltage strategy for estimating the reference DC link voltage, so that the charger can operate uninterruptedly under all voltage conditions (over voltage and under voltage). The adaptive DC link voltage also helps in minimizing the high-frequency ripple in the grid current. Due to which the total harmonic distortion (THD) of the grid current improves significantly. Because of this, the charger is able to maintain, the supply current THD below 5% in all operating mode. The designed charger operate with 230V, 50Hz single phase supply. The experimental test results captured in both steady state and dynamic conditions, validates the design and control of proposed charger.

This paper proposal is to investigate and understand the performance of the elevator systemr systems to optimize people traffic. Discrete event systems methodology is used in conjunction with heuristic optimization algorithm aiming to find the best scenario/symetric that reduces waiting time in elevators queues. The system modeling considers passive elements (queues) and active (processors/servers). The results show that changes in elevator scenario can shorten queuing time by up to 12.82% and with the optimization scenario 31,83%.

A Four-level Inverter system is presented in this paper, which employs a Space Vector Modulated Quasi-Z-Source to obtain high-boost inversion for PV applications. Unlike the conventional Multilevel Inverters, such as Neutral-Point Clamped (NPC) and the Cascaded H-Bridge (CHB) configurations, the proposed inverter uses only 19 power semiconductor switching devices and three Quasi-Impedance networks. It is also shown that by employing level-shifted carrier modulation, one can achieve higher shoot through duty ratio, enhancing the boosting capability of the proposed inverter. The performance of the proposed power circuit is assessed with simulation studies, which reveal its applicability for PV applications.

The work presents the results of a study regarding the impact of Demand Side Management actions on flexible loads distributed at the domestic end-users’ facilities in an isolated low voltage microgrid. Aim of the research study is to evaluate how the implementation of local control actions on the end-user’s side can impact on the operation of the isolated microgrid. The Demand Side Management is applied by each domestic user to optimize the operation of its own resources following well-defined operative steps. The study is carried out implementing a suitable model of the microgrid in Neplan environment, while the daily controlled load profiles of the end-users are evaluated using the Montecarlo approach implemented in Matlab. The results of the study are useful to the DSOs which will face all the issues rising in a fully-automated environment.

This paper deals with a proposed modified ROGI-FLL (Reduced Ordered Generalised Integrator Frequency Locked Loop) based control for a double stage, 3P4W (Three-Phase Four-Wire) grid-tied solar photovoltaic (PV) system. This modified FLL based control extracts the positive sequence components of grid voltages. This FLL based voltage control deals with the grid voltage issues such as voltage distortion and voltage unbalancing. The proposed robust FsLMS (Filtered-s Least Mean Square) based control strategy is used to extract the fundamental active current component of load to generate the reference grid current for DC-AC converter. The proposed LMS based control addresses multiple power quality concerns such as harmonics minimisation, grid currents balancing, and power factor correction. An INC (Incremental Conductance) based MPPT (Maximum Power Point Tracking) technique tracks the crest power, which is used to generate the gating pulses for the boost converter. The VSC (Voltage Source converter) is used to sustain the DC link voltage across the capacitor. The extricated solar PV power is used to feed the real power demand of load and surplus power is injected into the grid. The proposed system is simulated into the MATLABSimulink environment and a developed prototype is realised in the laboratory to validate the proposed control. Test results of proposed system shows satisfactory responses under various dynamic conditions such as varying solar irradiation levels, load unbalancing, grid voltage distortions and grid voltages unbalancing. The total harmonic distortions (THD) of the grid voltages and grid currents are observed well within the IEEE-519 and 1159 standards.
