This paper investigates the performances of PV plant installed in Southern Italy under mutable environmental conditions. This analysis has been performed on a measurement campaign, demonstrating how the performances of the PV system are influenced by the variability of solar irradiance. In fact, the more the irradiance level is high, the more will be the corresponding joule and thermal losses affecting the whole system. This evidence demonstrates the inadequacy of evaluation methods requiring a single instantaneous experimental verification of the minimum efficiency level used, for instance, for functional testing of photovoltaic systems.

Lithium-ion batteries are gaining importance for a variety of applications due to their price decrease and characteristics improvement. A good energy management strategy is required in order to increase the profitability of an energy system using a Li-ion battery for storage. The vast number of management algorithms that has been proposed to optimize the achieved profit, with diverse computational power requirements and using models with different complexity, raise doubts about the suitability of an algorithm and the required computation power for a particular application. The performance of three energy management algorithms based on linear, quadratic, and dynamic programming are compared in this work. A realistic scenario of a medium-sized PV plant with a constraint of peak shaving is used for this comparison. The results achieved by the three algorithms are compared and the grounds of the differences are analyzed. Among the three compared algorithms, the quadratic one seems to be the most suitable for renewableenergy applications, given the undue simplification of the battery aging required by the linear algorithm and the discretization and computational power required by a dynamic algorithm.

Phasor Measurement Units are widely utilized in power systems to provide synchrophasor data for a verity of applications, mainly performed by Energy Management Systems (EMS). Synchrophasors are measured at different parts of the network and transmitted to Phasor Data Concentrator (PDC) at a rate of 30–60 samples per second. The synchronization is done by means of a phase locked oscillator inside PMU which uses clock signal of the Global Positioning System (GPS). In this paper a novel charge pump with an appropriate operation capability in phaselocked-loops is presented. By using this phase locked loop in phasor measurement unit, the total performance of this circuit will be improved. The proposed charge pump uses current mirror techniques in order to achieve a wide range of output voltage to control the oscillator and also has a good performance in a wide frequency range from 33MHz to 555MHz. This circuit is designed and simulated in TSMC 0.18µm CMOS technology. The proposed charge pump only consumes 390µW power in supply voltage of 1.8V at 500MHz and has a maximum current of 16.43µA with an acceptable current matching between source and sink currents. It is also capable to be used in a wide frequency range and low power applications.

This paper deals with energy management in the urban microgrid dedicated to individual and collective self-consumption. This microgrid is connected to the national grid, with a possibility of bidirectional power flow. The studied microgrid consists of some building integrated photovoltaic systems, a community photovoltaic field and a community storage unit. The provided household devices and public services can be classified in three categories, namely as adjustable, schedulable, and critical loads. In this paper, a concept of self-consumption in urban areas is studied and the decision support laws in the management of energy flow are developed and proposed. The paper addresses aspects related to the overall supervision of the system, whose performance depends on the quality of the means of real time communication and information exchange. The study is performed according to a methodology that is based on a load forecasting methodology to develop the Energy Flow Management algorithm, which is validated using an experimental test bench. As contribution, this paper proposes a development of an optimized energy management strategy in an urban self-consumption microgrid based on an intelligent load forecasting method. The results are presented and analysed in this paper.

Hybrid Multi-Level Inverter(MLI) topologies are gaining attention over conventional ones due to their extended applications in the power, industrial and renewable energy sectors. MLIs are optimized which can provide compact size, reduced cost and higher efficiency compared to the conventional types. In this paper, a hybrid structure of novel three-phase seven-level inverter is proposed. This topology is a combination of cascade-connected two-level cells and H-bridge cells with flying capacitors (FCs). The operating principle and the balancing technique for the DC-link capacitors and FCs are also presented. The generation of various output voltage levels using Sinusoidal Pulse Width Modulation (SPWM) is presented. The comparative analysis is carried out to show the number of components in the proposed circuit configuration and their voltage ratings are considerably lower compared to the conventional and recently proposed topologies. The performance of the proposed topology is verified with simulation studies and also in the experimentation. The simulation and experimental results validate the effectiveness of the proposed topology and the control technique.

Although the power electronics converters involved in glass furnace boosting process may be as diverse as require the electric heating system, in tin bath and annealing lehr heating systems a thyristor based AC-AC voltage converter controlled by integral cycle control (ICC) is often employed, distributed over the multiple heating zones. The ICC is widely used due to its multiples benefits such as low transient current, increased reliability and limited harmonic distortion, but noteworthy at low frequency. The goal of this research is to establish an optimal demand response (DR) and power quality (PQ) strategy using a hybrid technique derived from ICC through a straightforward algorithm characterized by a low computational cost that provides successful results for both thermal stability as well as from the PQ and DR point of view.

This work proposes to evaluate the electric power generation capacity that can be produced with the installation of photovoltaic systems on the roofs of the Campus of the Federal Institute of Goiás - IFG. The research is divided into two procedures: I) simulation of four panel mounting configurations and; II) evaluation of the electric power generation capacity of the campuses to supply the consumption and inject the surplus in the network of the concessionaire. Photovoltaic systems are dimensioned according to the useful roof area defined by the shadowing studies. The results of the simulations show that the configurations n° 01 and n° 02 are technically more advantageous having as reference criteria of use of the available area, maintenance, economy and safety. The results indicate that, with the exception of one campus, the other evaluated fields have the capacity to generate photovoltaic solar energy in sufficient quantity to meet the own consumption and also to deliver the surplus to the network of the concessionaire, also making it possible to propose compensation among consumer units.

The following paper encompasses a simple yet novel and robust control strategy to mitigate the adverse effects of Pulsed Power Loads (PPL) in the naval shipboard comprising of AC/DC micro grid. The control strategy is optimally designed for a carefully crafted AC/DC Hybrid infrastructure consisting of Photo-Voltaic (PV) and Hybrid Energy Storage System (HESS) consisting of battery and supercapacitor(SC). The promising nature of the control lies in the fact that any power surge in the DC bus is transiently handled by the super-capacitor owing to high power density whereas the battery ramps at a rate slower than its HESS counterpart. The uncompromising property of the control lies in the fact that it has been taken to account for the battery and the SC dynamics, thus it enhances the lifetime of the battery in addition to it reduces the maintenance costs of the battery. Above all the reliability of the power is further ensured by taking into account a gas powered generator which comes into play when the PV power falls short at the DC bus. The above said philosophy is validated in MATLAB/Simulink with the proper justifications.

In this paper, the switching command is produced by a sliding mode controller so that inverter output current follows the load current. To this end, an appropriate sliding surface for inverter output current is first defined, whereby control law is derived. In grid-connected mode of operation in microgrids, it is desirable that the microgrid meets its local load and does not receive power from the main grid as far as possible. Moreover, the voltage and frequency of the point of common coupling (PCC) are determined by the main grid having high inertia. Hence, in this paper the control strategy is focused on the inverter output current. Furthermore, the performance of the proposed sliding mode controller is compared with that of a PI controller. Also, hyperbolic tangent function is used instead of sign function in sliding mode control approach to cope with the chattering phenomenon. Finally, the results obtained via simulations performed in MATLAB/SIMULINK environment show the superior performance of proposed controller for a variety of load types such as linear and nonlinear load.
