Short-Term Load Forecasting (STLF) is nowadays a crucial and integral part of the energy production procedure to the emerging technologies for demand side management. The numerous approaches and algorithms proposed take advantage of the advances in information, metering and control technologies to address the challenges of distributed generation and intermittent energy sources on the one hand and the electricity markets on the other. This paper describes a flexible and easily customized, modular toolbox, called Divinus, for electricity use profiling and forecasting in microgrids. Divinus supports algorithms for forecasting and profiling that can be used independently or combined and its architecture consists of several interconnected well-defined components where each one interacts directly with the other. In this work, we have implemented Self-Organizing Maps for profiling and k-Neighbors for forecasting. In order to test the functionalities of the platform, we used electricity consumption data of the TEISTE campus in Evia, Greece from January 2010 till March 2018. From the tests that have been carried out so far, we have observed that the proposed approach yields high accuracy and acceptable mean errors.

Fast trolleybus acceleration causes high power peaks in the overhead network. For this reason, smoothing of power peaks has been a topical issue in the field of electric public transport. In part, this can be achieved through energy storage systems capable of storing braking energy that can be reused during the next acceleration. This paper compares the possibilities to apply mobile energy storage systems for two trolleybus types of standard Škoda 24Tr and articulated Škoda 27Tr. Idealized motion simulations were made in Matlab/Simullnk environment.

By grid optimization, the determination of the size of the fed zone, when per unit cost of electricity delivery - the cost referred to transmitted energy - is minimum, is understood. Per unit cost is a function of substation cost and of fed zone grid indexes: length of the power lines and the amount of their material, losses of energy and of voltages which, in turn, are functions of the fed zone size. The indexes are different for various fed zone shapes. When outlines of a fed zone are not defined topographically, the most profitable shape of the zone is hexagon. However, the square or some other fed zone shape sometimes can be more acceptable due to the location of consumers. These indexes are defined in the paper. Besides, it turns out that, when minimizing the per unit cost of electricity delivery, a binomial of a fed zone main size is insufficient to represent the said per unit cost; it is shown here that a trinomial or even four-term polynomial is necessary to represent the per unit cost of electricity delivery.

Due to the increasing penetration level of microgrids (MGs), it becomes a critical issue for MGs to help sustaining power system stability. Therefore, this paper is aimed at investigating comparison between transient analysis AC and DC Microgrid connected to the grid in case of using Superconducting Fault current limiter (SFCL) at the connection point of Microgrid and grid. When the three-phase-to-ground fault is applied at connection point of Microgrid and grid, the SFCL minimized the oscillating currents and the active and reactive power of AC and DC microgrid to range 20-30%. The transient analysis of AC microgrid is better than DC microgrid except the values currents and the active and reactive power are very high during the fault. The time required to recover pre-fault values of AC microgrid (0.1 sec) is less than those time of DC microgrid (3 sec).

The purpose of this paper is to introduce readers with a proposal of a new approach of permanent magnet synchronous motor with arc shaped stator for wheelchair application. The arc shaped stator allows user to vary motor power and in the same time it’s torque by removing or adding arc shaped modules of the stator. It is an excellent opportunity allowing to adjust motor power according to users weight. In the same time it allows to save money when comparing with the same type of motor with a whole stator.

In this paper, the frequency spectrum of a three- phase induction motor’s stator current on a linear scale is investigated. The broken rotor bar, spatial and grid fed harmonics are taken into consideration. Since the fundamental component of the power supply is always the most powerful component, it makes the spectrum less legible, increases the spectral leakage and makes the logarithmic scale inevitable. In this paper, a Chebyshev filter is used for attenuation of the fundamental component, because of its good transition band and no passband ripples. The current signals are taken from both simulation and laboratory environment and harmonics due to above-mentioned causes are segregated.

A new method for on-line grid impedance estimation is presented in the paper. It is based on an algorithm that requires no measurements from other buses. What is more, in normal operation it does not need to inject any current to the grid at the point of common coupling as it common in active methods for impedance estimation. The paper includes a mathematical derivation of the key equations, simulation results for a simple test system as well as performance evaluation. Laboratory tests are ongoing.

A New L-L and L-2L Multilevel Boost Converter topologies (L-LMBC and L-2LMBC) are proposed for photovoltaic (PV) energy application. Both L-LMBC and L- 2LMBC topologies are designed to provide a viable and effective solution for photovoltaic energy applications that requires a high voltage conversion ratio (VO/Vin) like photovoltaic system to fed MLI (PV Multilevel Inverter System), Electrical Drives (ED), Hybrid Electric Cars (HEC) etc. L-LMBC topology is designed with connecting the Cockcroft Walton (CW) multiplier to an upper L converter of the L-L topology of XY family. Similarly L- 2LMBC topology is designed with connecting the Cockcroft Walton (CW) multiplier to 2L converter of the L-2L topology of XY family. The operation of L-LMBC and L-2LMBC is discussed with mathematical expressions in details. The attractive features of proposed L-LMBC and L-2LMBC topologies are discussed in details. The L-LMBC and L-2LMBC are simulated in the Matrix Laboratory version 2012 (MATLAB-2012) and the result of simulation confirms the operation, functionality and design of the proposed converter.

In this paper, a model predictive control (MPC) based on the indirect continuous-control set (CCS) is proposed for regulating the grid current waveform provided by a PV grid-connected single-phase inverter. It involves a three-level NPC quasi-Z-source (3L-NPC qZS) inverter, an only-string PV array, and a LCL output filter. From a finite set of modulation index values, the proposed indirect CCS-MPC current control selects one of them for an external fixed switching frequency driver based on LS-PWM strategy. An issue regarding cost function composition and modulation index regulation is also proposed for improvement of transient and steady-state responses. Simulations results from a PSCAD/EMTDC model are presented and discussed. Even limited by a fixed switching frequency, obtained results demonstrate: an acceptable accuracy of the proposed system model; and a robustness of the evaluated indirect CCS-MPC grid current method under some external perturbation conditions.
