In this paper, novel minimum ampere per torque strategy of induction machine drive including iron loss phenomena is presented. Generalized formula for optimal distribution of current vector, by means of exploiting the torque generation capability, is developed, which takes into account the effects of magnetic losses within the controller. Modeling of iron losses is done by considering the classical approach of inserting active resistance in parallel with the magnetizing branch of induction machine equivalent circuit. Verification of the proposed optimal algorithm is performed through the simulations of the vector controlled induction motor model with included iron losses.

The security concerns are a very important aspect of the Software-Defined Networking (SDN) concept since the security is not a built-in feature in the architecture. The decoupling of the data plane from the control plane has created completely new loopholes specific to the SDN. Using Link Layer Discovery Protocol (LLDP) for topology detection in SDN brings some of these new specific vulnerabilities, such as link discovery attack in the southbound interface. The problem concerns every implementation that uses the LLDP-like packets for link discovery. Network Configuration Protocol (NETCONF) together with YANG (yet another new generation) modeling language, used as a southbound interface (SBI) in the SDN can help to defend off this attack. This paper proposes the specific usage of NETCONF protocol and modeling abilities of the YANG language. The given enhancement will enable the network controller to recognize the link discovery attack threats.

This paper is a study on a single input dual output non-isolated DC-DC converter topology, its design, and its control strategy. This topology has the benefits of low switching stress, reduced passive component sizes and high efficiency. A closed-loop control system has been designed based on a small-signal model derived in order to regulate the output voltages along with the capacitors’ voltage balancing. SPICE based simulation is carried out for analysis. Scope of this converter in the application in grid connected systems with simultaneous battery charging is also analyzed.

The monitoring of wireless networks is one of the important aspects to ensure the reliability, stability, and performance of the service they provide. However, monitoring can be a challenging task, especially in the case of Low-power Lossy Networks (LLNs). LLN networks are designed with low power usage in mind and they are typically much more constrained than conventional computer networks. For instance, nodes found in LLN networks are typically battery/solar-powered, mounted with short-range transceiver, constrained storage space and memory, low computational power, and run a custom operating system (OS). This paper presents the approach of the LLN network monitoring. For proof of concept, a wireless network is formed in the experiment, consisting of VESNA sensor nodes. Nodes are mounted with IEEE 802.15.4 compliant radio chip and loaded with custom embedded Contiki-NG configured with channel hopping protocol stack (6TiSCH) for communication. To monitor LLN infrastructure, the experiment gives an example of integrating existing state-of-the-art technologies, such as MQTT for machine-to-machine (M2M) communication, and Zabbix for data visualization. Results of the experiment are given as Zabbix graphs that show various readings from nodes.

Currently, the leading manufacturers of integrated circuits produce Sigma-Delta ADCs, focused on the application as a part of a measurement channels of power quality (PQ) instruments. The magnitude response of such an ADC is determined by a built-in digital filter, usually with an cascaded integrator-comb (CIC) filter structure. However, the magnitude response of this filter (from the point of view of the low-pass filter function) do not have the required parameters: the filter has a slope of the magnitude response (MR) in the passband and a relatively large bandwidth between passband and stopband. In this article, two variants of the method for correcting the Sigma-Delta ADC magnitude response which is a part of PQ instrument measurement channel are considered. The first approach involves the application of a single corrective digital filter that compensates the Sigma-Delta ADC passband ripple and reduces the bandwidth between passband and stopband. The second approach involves the application of two corrective digital filters, one of which compensates the ADC passband ripple, and the other one reduces the stopband frequency. Both options considered assume the application of Matlab built-in functions. The methods for calculating the coefficients of the correcting filters are considered for both approaches. By the application of simulation modeling, the characteristics of the PQ instrument measurement channel, which contains the CIC filter and the compensating filter, are obtained. The possibility of modeling the PQ instrument measuring channel in the Simulink software package is considered. The features of modeling of the blocks of the CIC-filter, filter-compensator and data format conversion for the case of the PQ measurement channel are analyzed.

Electrical power systems throughout the world experience an unprecedented transformation. One of the main motivation for this is a transition from conventional power generation technologies towards renewable energy sources (RES). This transformation has numerous positive effects on power systems, environment and social engagements on a global level. However, poorly planned and allocated RES add complexity to power systems operations and can cause numerous challenges. This paper investigates some of the most common parameters used in the RES grid integration process. In particular, the impact of different PV penetration levels on energy losses and transformer current loading in a PV predominated power system are presented. The analysis is performed in DigSILENT® Powerfactory software using quasi-dynamic analysis on a modified IEEE 14 bus system. The results demonstrated that the energy losses could be reduced until the critical point of PV penetration. After the critical point is reached, the energy losses start to grow rapidly. The current loading of the transformers also tend to reduce with the increase in PV penetration until the critical point and rapidly grow after the critical point. In conclusion, results presented in this work demonstrate the importance of appropriate RES integration planning and analysis, which remains an important engineering task.

The power electronics and many other systems applied to power networks have undergone significant transformation and maturation in the last three decades. Although further advancements are possible and expected, currently the convergence towards feasible paradigms is of great importance for researchers. Hence, besides the overview of the novelties and trends in the development of smart grid-related systems, this paper presents the feasibility and effectiveness analysis of the emerging smart grid systems. Most notably, systems enabling novel approaches to how energy is produced and consumed, but also stored and traded with were addressed. The mentioned analysis is loosely based on what is usually defined as PESTEL analysis - several technical and nontechnical aspects of importance for the development and implementation of the mentioned emerging technologies and concepts were regarded. The investigation was conducted from the perspective of both developed and developing countries.

This paper considers a stand-alone wind energy conversion system (WECS) designed for dc load supply and battery charging. An indirect rotor-field-oriented (IRFO) control scheme is applied for the wind turbine (WT) driven induction generator (IG). High level of agreement between the actual IG and the IRFO controller is ensured by including the IG stray load and iron losses as well as the magnetic saturation in the control algorithm. Within the considered IRFO controller, the reference flux is adjusted to achieve minimum IG losses. Similarly, the WT speed is controlled to ensure maximum WT power at different wind speeds. To achieve this, it is essential that the actual WT speed closely tracks the reference and that it is robust to disturbances in the system. The proposed hedge algebra (HA) speed controller is here for the first time experimentally implemented within a WECS. Its performance is evaluated over a wide range of wind speeds by using a 1.5 kW experimental setup with the DS1103 controller board (dSPACE). To avoid speed sensor, the rotor speed is estimated by means of the model-reference-adaptive system. The obtained results show superior performance of the HA controller in terms of overshoot, settling time, and disturbance rejection in comparison with a conventional PI controller.

Existing system for registration of electric energy consumption is based on the application of commercial power meters and/or measuring groups at each load/consumer. National standards stipulate that the power meters register active, and measuring groups register both active and reactive energy. These requirements give a correct picture of consumption in systems where linear loads dominate. Unfortunately, the needs of electric energy consumers have significantly changed in recent years, so the number of nonlinear loads has increased remarkably. Non--registration of distortion component of power causes losses in power system that are proportional to power and number of nonlinear loads. Measurement results of the consumption of different types of modern loads have confirmed our presumptions. Modification of built-in power meters and measuring groups is proposed, so that it easily fits into the existing system.
