The squirrel cage induction motor direct torque control main problems due to torque and large stator flux pulsation. In this an improved model predictive direct torque control algorithm considering multi-step delay compensation is proposed. At each sampling moment, predict the stator flux linkage and torque at the next moment under each voltage vector. The optimal voltage vector deviation from the stator flux linkage reference value and torque reference value are selected as the minimum objective function. Aiming at the problem of one-shot delay in digital control systems, a multi-step predictive delay compensation measure is studied. Simulation shows that the algorithm can effectively reduce torque and stator flux pulsation, reduce current harmonic distortion, and solve the delay problem in digital systems.

Nowadays, active power filter (APF) is the most popular device for harmonic compensation. This paper presents the soft computing techniques for compensation of currents harmonics using a shunt active power filter (SAPF). The method includes a 3-phase supply system with a current-controlled voltage source converter (CC-VSC) having an input coupling inductor and output tank capacitor for a self-supported DC bus. The performance of the active power filter can be enhanced by using soft computing techniques such as artificial neural network (ANN) controller and gravitational search algorithm (GSA) for generating control signals of the SAPF. The current reference is calculated to compensate source current THD with synchronous reference frame (SRF) technique with proportional integrator (PI) controller. From the result, it is evident that both the soft computing techniques reduce the computational time & fast convergence which improves the filter performance during the transient period and makes it self-tuned. The proposed structure is simulated using MATLAB/Simulink and subsequently experimentally verified. The presentation of the system is originated to be suitable for numerous features of power quality enhancement structure.

Class 5 flexible aluminum conductors are not common in cable manufacturing industry due to insufficient study on cable joints and connectors. The table of ampacities for aluminum conductors at 110 °C in AS/NZS3008.1.1 standards are also not available as a reference guide for electrical system designers that restricts the installation of aluminum low voltage (LV) cabling system to operate at 90 °C of conductor maximum operating temperature where 110 °C cables are permitted in Australia. In this paper, the cable ampacities of various LV Class 5 flexible aluminum cables at maximum operating temperature of 110 °C are calculated using IEC60287 and AS/NZ3008.1.1 standards. The calculated ampacities from the formula presented in clause 4.4. of AS/NZS3008.1.1 are verified by using the 6kA inductive current generator to determine the suitability for use. The joint temperature between cable and shear bolt mechanical connectors are simultaneoulsy simulated using the calculated ampacities to determine the suitability of mechanical shear bolt connectors when the coefficient of thermal expansion of material is considered. The observed differences between the calculated and measured values demonstrate the relevance of formula used in determining the current ampacity at 110 °C conductor temperature in free air.

In the near future, the digitalizing world will continue to improve and the need for DC based devices will be increased beyond doubt. Today’s electrical grid is strictly dependent on AC-DC rectifiers. Each conversion process means additional power losses and signal quality deteriorations for the network. In addition, networks which are fed by batteries and renewable sources such as solar panels, and wind turbines are suffering from conversion-based power losses. In this respect, the idea of switching to DC on the low voltage side of the networks has become an intriguing subject. In this study, the applicability and efficiency of the low voltage direct current (LVDC) concept for low voltage distribution systems is discussed and a sample LVDC distribution system is analyzed. In this operational residential application electrical transient analyzer program (ETAP) is employed for comparison of different voltage levels such as 110 V DC , 250 V DC , 320 V DC and conventional 220/380 V AC . As a novel approach different DC voltage levels are compared with typical AC system in detail. Comparative analysis is conducted for safety regulations, voltage drops, current carrying capacities, power consumption and harmonic calculation of the proposed system. In this respect applicability, possible drawbacks and future aspects of LVDC systems are interpreted.
在不久的将来，数字化世界将继续改善，对基于直流的设备的需求将毫无疑问地增加。今天的电网严格依赖于交流-直流整流器。每个转换过程都意味着额外的功率损耗和网络信号质量的恶化。此外，由电池和可再生能源(如太阳能电池板)以及风力涡轮机供电的电网正在遭受基于转换的电力损失。在这方面，在电网的低压侧切换到直流的想法已经成为一个有趣的主题。本文讨论了低压直流(LVDC)概念在低压配电系统中的适用性和效率，并对一个低压直流配电系统进行了实例分析。在这个可操作的住宅应用中，电瞬变分析仪程序(ETAP)用于比较不同的电压水平，如110 V DC, 250 V DC, 320 V DC和常规220/380 V AC。作为一种新颖的方法，对不同直流电压水平与典型交流系统进行了详细的比较。对系统的安全规程、压降、载流能力、功耗、谐波计算等进行了对比分析。在这方面的适用性，可能的缺点和LVDC系统的未来方面进行了解释。

This paper proposes a new and simple method to incorporate three-phase power transformer model into distribution system load flow (DSLF) analysis. The objective of the present work is to find a robust and efficient technique for modeling and integrating power transformer in the DSLF analysis. The proposed transformer model is derived based on nodal admittance matrix and formulated by using the symmetrical component theory. Load flow formulation in terms of branch currents and nodal voltages is also proposed in this paper to enable integrating the model into the DSLF analysis. Singularity that makes the calculations in forward/backward sweep (FBS) algorithm is difficult to be carried out. It can be avoided in the method. The proposed model is verified by using the standard IEEE test system.

The active power filter has proven to be an effective method for attenuating harmonic currents generated by non-linear loads as well as for compensating reactive power. This paper presents a comparison study between two control methods associated with a shunt active power filter based on eleven-level type cascaded inverter. The first method is based on the conventional PI regulator and the second is based on the predictive current controller. The eleven-level type cascade inverter has more advantages relatively to the two-level inverter; among them: better total harmonic distortion, reduced semiconductor switches ratings and reduced switching losses. The performance of the APF is tested by simulation using Matlab/Simulink. The predictive controlled the APF associated with the multi-level inverter shows more performances and efficiency compared to the conventional control algorithms.

This paper investigates optimal PID controller tuning using Particle Swarm Optimization for frequency control in the microgrid system. The proposed microgrid composed of renewable sources like wind turbine generation and solar system with diesel engine generator and storage systems such as the battery, flywheel, aqua electrolyser, and fuel cell. The microgrid based on renewable energy sources face different challenges in operation and stability due to the stochastic nature of solar radiation and wind speed that depend upon the weather conditions. Among these challenges the frequency and power deviations are affected by the sudden unbalance between generation and load which require a suitable and an adequate regulation. The main objective of this study is to reduce the frequency and power deviation by the use of PID controller optimized using particle swarm optimization due to its simplicity and flexibility to overcome this kind of issues. The simulation results show the better performances and robustness of the proposed controller against the disturbances in load and generations in comparison to using Genetic Algorithm.

This paper presents the direct torque-controlled induction motor drives (DTCIMDs) based on a retrofit 44-pulse rectifier (44PR). A 22-phase polygon autotransformer (PA) is designed to supply the rectifiers. The above structure improves the power quality standards in the power grid and complies with the requirements of the IEEE-519 standard for different loads. Besides, a power factor close to one is obtained for a wide range of DTCIMD performance. The results show that the total harmonic distortion (THD) of the input current under variable loads for 44PR is less than 3%.
