In this paper a new electric power structure for solar powered unmanned aircraft system is proposed. The presented topology is a prospective improvement to both Solong and Zyphyr models. The proposed UAS model utilized Zyphry UAS by using ac bus-line instead of dc bus-line to supply the propellers. The system involves PV array, lithium sulfur based energy management system, dc bus-line, inverter,...
This paper presents an investigation on the comparison between the Maximum Torque Per Ampere (MTPA) and the Field Orientation Control (FOC) algorithms for interior permanent magnet synchronous machines (IPMSMs). In particular, this study was carried out on a small-power IPMSM with low salience ratio. Both control algorithms have been implemented in the Matlab/Simulink environment, obtaining promising...
This paper aims to analyze the enhanced performance of grid connected transformerless inverters (GCTI) by the application of novel Wide Band Gap (WBG) devices with modified PWM. Highly Efficient Reliable Inverter Concept (HERIC) is chosen for this study because of its excellent common-mode noise cancellation capabilities and numerous solar photovoltaic applications. HERIC inverter works efficiently...
The purpose of this document is to give a wide-ranging comparison between different photovoltaic (PV) maximum power point tracking (MPPT) methods. The MPPTs considered in this work are perturb and observe (PO), incremental conductance (IC), sliding mode (SM), and fuzzy logic (FL) tracker. A model of MSX 60 solar module and the different MPPTs applied to a boost chopper was simulated by means of Matlab/Simulink...
This study investigates the effectiveness of a time-frequency analysis of photovoltaic signals with transients caused by shading on the solar panel. The prototype experiment for the signals acquisition was performed by simulating the desired disturbances on the photovoltaic panel. In this direction, the signals were analyzed by a scheme called variable short-time Fourier transform, that has a varying...
This paper presents a methodology for optimizing the size of energy storage system (ESS) for maximizing the capture of energy regenerated by a train. Besides, minimization of energy consumption from the substation, in order to obtain a return on investment, has also been explored. A standard structure of rail transit system has been used here for analysis. The optimization process takes into account...
This paper proposes a novel simple adaptive and online approach to estimate the state of charge (SOC) in Lithium Ion (Li-Ion) batteries based on a new model parameter identification method. First, a novel discrete model for the Li-ion battery is developed. This model is the key step in the development of the proposed parameter estimation algorithm. The estimated parameters are used for on-line calculation...
In those electrical systems with an implemented secondary voltage regulation based on the reactive power of traditional fossil fuels power stations, it becomes more important that new renewable sources power plants participate to the voltage control. In this paper it is studied a voltage control for large photovoltaic systems. The control is applied to an actual large photovoltaic power plant. Simulations...
In this paper, the application of genetic algorithm (GA) to energy management of isolated power system is discussed. A method to realize the simultaneous optimization of configuration and operation with emergency generators (EGs) in a hospital is proposed as an example. The simultaneous optimization of configuration and operation needs search of enormous combinations, which is generally considered...

Solar irradiance prediction has a significant impact on various aspects of power system generation. The predictive models can be deployed to improve the planning and operation of renewable systems and can improve the power purchase process and bring several advantages to the power utilities. The irradiance is affected by several factors, such as clouds and dust, and it becomes challenging for physical...
Supporting frequency inside of each generation area as well as keeping proper synchronism condition between interconnected areas are two main challenges for grid operators. In this paper, after analysis of structure of Renewable Static Synchronous Generation unit based on Synchronous Power Controller (RSSG-SPC) for holding and control of frequency, it is shown that how a renewable unit based on SPC...
Short term prediction of energy consumption of residential houses is of increasing interest as self sustainable off grid energy solutions as well as distributed generation and energy exchange grids are developed. In areas with non-temperate seasons, weather conditions induce noticeable changes in consumption patterns depending on the tenant's air conditioning settings and the house's exposure to the...
This paper presents an interfacing system of a photovoltaic (PV) array with an electrical grid based on a dual cascaded inverter. The PV array is connected to the main inverter through a boost converter, for maximum power extraction, while the dc-side of the auxiliary inverter is connected to a capacitor bank. The main and auxiliary inverters are controlled to deliver the harvested maximum power from...
Currently, solar energy is the primary source of energy for space missions. The development of space systems is affected to many fields: the study of space itself, the science of materials and especially the field of energy. Indeed, solar panels are the only non-nuclear means that enable satellites in orbit to be fed continuously. The efficiency of these solar cells increases. Current triple junction...
Electric power grids and complex computer systems have many similar properties of the operation behavior and the structure. A microgrid can be treated as a small electric grid that contains consisted of numerous residential loads, energy storage units, and distributed energy. The goal of implementing microgrids is to supply power to homes even in the event of an electric grid outage. That is, the...
