Researches have been conducted on the surrogate-modeling for better trade-off between solution accuracy and solving effort in design space exploration. In this paper, a robust method combining the deep-learning technique, image-transfer, with finite-element-modeling (FEM) in the electric machine optimization to accelerate the convergence is proposed. Specifically, a conditional generative-adversarial network is built to learn from the FEM simulated data about the relationship between the geometric drawing input and magnetic field plot output. The learned model can obtain the result 24x faster than finite-element modeling while maintaining the accuracy. This approximation model is then applied as the sample filter prior to the FEM in the genetic-algorithm powered optimization framework. The test done on a V-shape magnet motor optimization shows that closely matched Pareto-frontier can be found by this approach while the computing time is reduced by >50% at beginning stage for acceleration.

In a free electricity market where electricity is purchased on the stock exchange, it is necessary to purchase a corresponding amount of electricity at each local interval. All parties involved have provided electricity for purchase as accurately as possible, and therefore it is necessary to make as accurate a forecast as possible to the next trading interval so that no adjustments should be made as little as possible at the appropriate trading interval. The use of artificial lighting plays a major role in the changes to the consumer pattern curve, where it changes daily from sunrise and sunset, respectively.

An increasing number of fire and electric shock accidents in power sector increases the need for high impedance fault (HIF) detection as the existing over-current relay in the system is not able to detect the HIF state. The HIF detector employing sequence components of current along with voltage is proposed in this paper. The proposed HIF detector composed of two components i.e. current HIF detector and voltage HIF detector, in conjunction with existing distribution network set up. The first component analyzes current sequence components when fault appears in the network whereas later analyzes voltage sequence components. The current HIF detector operates when, significant amount of zero and negative sequence components starts appearing in the network. On the other hand, voltage HIF detector assists the current HIF detector in confirming the HIF state by examining the negative voltage sequence component. The performance of combined detector is evaluated by inducing high impedance fault at different nodes on the IEEE-6-bus radial balanced distribution system. The proposed detector makes use of only current and voltage of the system for HIF detection and doesn't require any additional feature extraction phase. The HIF detector in the proposed paper requires only one unit of sequence converter. Now, sequence components coming out from sequence converter are fed to HIF relay logic which is used in conjunction with existing over-current relay. Hence, this detector is cost effective as compared with the different HIF detectors presented in literature. The proposed method is simulated in a simulation environment. This method is fast and reliable as it detects the fault within one cycle.

Nowadays Liquid Crystal Display (LCD) is an integral part of humans' everyday life. They are used in everything starting from cell phones and televisions to washing machines. Liquid Crystals (LC) have far wider applications, one of them - smart or switchable glass, glass with voltage dependent optical properties which can be altered if specific electrical signals are applied to the glass. Bistable smectic-A (SmA) LCD is one of the most promising devices for smart glass applications due to long term bistability, low haze at clear state, low transmittance at scatter state and low power consumption. Every product that has been developed needs to be tested to verify and validate the design and development processes. To make sure the product is safe for customer, complies with necessary product, product group and manufacturing standards, performs the function it is required to perform. In this paper bistable smectic-A liquid crystal display extended functional testing methodology is presented. As well as the most common defects that appeared during and after the testing are reviewed and analyzed.

Transport sector in Latvia have several challenges: energy consumption decrease, produced CO2 emission decrease, air pollution decrease, reduction of the average age of the car in the country, integration of renewable energy source to replace fossil fuel. Electric vehicles have high potential in the future to help achieve directive 2018/2001/EC targets. This study presents a cost-benefit analysis of electric vehicles, as well as an internal combustion engine with diesel and gasoline. The cost-benefit analysis methodology was developed considering car production, purchase, operating and utilization costs. Environmental aspects such as air pollution, climate change and noise were also taken into account.

X-linked polyethylene (XLPE) cables are widely dispersed in grids of 110 kV and supposed to be used in specific environmental conditions because of its compactness and higher structural durability, resistance, and stability. These conditions may include laying in urban centers and cites or through different watercourses when traditional overhead lines application is impossible or unacceptable. Wherein, XLPE cables require a precise calculation of geometrical parameters of their laying, identification of optimal sheath grounding and phase transposition, etc. For example, close cable spacing may lead to thermal damages of all cores after single-phase short circuits. In its turn, the cable sheath transposition allows transfer capacity increasing, which is critical in grids of metropolises. In this paper, the authors propose a series of case studies and calculations, which allow identifying an optimal solution for three-phase cable line placement.

This paper is devoted to the problem of the phasor measurement units (PMUs) placement for power system state estimation using optimality criteria proposed by the theory of optimal experimental design, such as A-, D-, M-, I-, G-optimality criteria. The high complexity of the task posed limits on the possibilities of solving it by exact mathematical methods only to small scale power systems. The paper studies the possibility to use population-based optimization algorithms (Genetic Algorithm, Differential Evolution, Particle Swarm Optimization, and Ant Colony Optimization). To meet the state observability requirements, the repair procedure is incorporated in the population-based algorithms. This allows to overcome the drawbacks in the existing methods based on the assumption of a priory observability of the power system and to take into account the system contingencies such as the phasor failures, the PMU losses, and the branch outages. We demonstrate the effectiveness of the proposed method in terms of the PMU placement design's efficiency and computation efforts through the numerical simulations on a standard IEEE 118-bus system.

During last decades, due to continuous increasing power demand and advancing technology, microgrid (MG) has become more popular. Renewable energy sources stand itself as one of the power generation sources in such microgrids. This paper introduces a hybrid AC microgrid (ACMG) comprising a storage system, wind turbine, diesel generation (DG), and microgrid control center (MGCC), which was capable of operating isolated or interconnected with main grid. A power control strategy is proposed based on the data received from the MGCC, which improved the power reliability and stabilized the power system during power failure An experimental modeling platform was used to analyze the grid behaviors in MATLAB Simulink. The observed results confirmed that the proposed strategy enhanced the power efficiency and stability in the proposed microgrid.
