Increasing energy demand and recent advancements in electrical and distributed generation (DG) technology have made power systems complex. Therefore, the reliability assess-ment is important for efficient planning and operation of distribution networks. The system reliability can be improved with the optimal DG integration and energy management schemes. This work mainly studies the impact of optimal DG planning with an energy management scheme on the reliability of a radial distribution network. Usually, the reliability of a power system is evaluated using the distribution system reliability indices, which are based on load point and customers. The voltage-dependent load model and time-varying load profile for different load classes are included in this work for pragmatic planning. Particle swarm optimization (PSO) algorithm is used to find the optimal site and size of DG units and optimal scheduling of the shiftable loads. The proposed model of optimal DG allocation with energy management is evaluated with a case-based analysis. The modified IEEE 33-bus distribution system is considered in this model to demonstrate the improvement of reliability and operational parameters. Simulation results verify the efficacy of the model.

The article presents the design and implementation of an integrated power converter (IPC) for a switched reluctance motor (SRM) drive based electric vehicle (EV) application. The IPC proposed integrates driving and battery energy storage (BES) charging/discharging functionality. During BES charging mode, i.e., grid-to-vehicle (G2V) charging, the proposed IPC is reutilized as a bridgeless boost power factor correction circuit (PFCC) in cascade with a bidirectional DC-DC converter (BDDC). Similarly, during BES discharging mode, i.e., vehicle-to-grid (V2G) charging, the proposed IPC is reutilized as a BDDC in cascade with a single-phase voltage source inverter. Thus, with the proposed IPC, the BES can be charged/discharged at AC grid voltage. The proposed IPC also supports DC fast/vehicle-to-vehicle (V2V) charging wherein the host EV via the integrated BDDC can charge/discharge a receiver EV of higher or lower BES voltage rating than the host EV. In addition, during G2V, V2G and V2V charging, the charging current flowing in phase winding/s when reconfigured as charging inductor/s results in a zero-torque production. Detailed theoretical analysis and experimental verification on a prototype 4-phase SRM are presented to evaluate the proposed IPC's driving and BES charging features.

Growing electricity demands combined with drastic environmental changes have led to the penetration of renewable distributed generations (DGs) close to the load via the adoption of microgrids. However, the intermittent nature of solar based DGs complicates the protection of hybrid microgrid system. Integrating the microgrid system with battery energy storage system (BESS) ensures the reliability of power supply during dual operating modes. The role of BESS during the maximum and minimum demand scenarios has been discussed for grid-connected mode. Further, a reliable fault detection classification scheme using Discrete Wavelet Transform (DWT) and Linear Discriminant Analysis (LDA) approach has been proposed for hybrid microgrid network integrated with BESS. The proposed scheme has been validated for fault and no-fault cases and found effective for varying fault locations, fault inception angles, and fault resistances in both the microgrid operating modes.

The charging infrastructure for Electric Vehicle (EV) has major demands in recent years. Considering Solar Photovoltaic (PV) as the input reduces dependency of Power Grid. This literature presents Modified Z-Source Inverter (MZSI) that provides boosted output to charge the battery through charging unit and supplying to grid. The dc-ac conversion stage is reduced from multi stage to single stage with the help of Z-Source Inverter (ZSI). In this article, three ports such as PV has input source, Grid and Battery charging unit are considered as output ports with MZSI as a converter. Multiple ports has been created by splitting the capacitors across switches in MZSI for connecting multiple battery charging unit. This topology operates in different modes such as PV to Grid, PV to Battery, Grid to battery and Battery to Grid. In this work, lithium ion battery is considered for the analysis purposes. The results and analysis carried out in MATLAB/Simulink and the results are obtained which shows that multiple vehicles can be charged with this topology.

In this article, a Mixed Norm based LMS control algorithm updated with s reweigh ted zero attraction parameter is implemented for power conversion in a two-stage solar photovoltaic (SPV) system interconnected with the three-phase grid. The boost converter extracts peak power from the SPV array by application of the incremental conductance (INC)-based maximum power point tracking (MPPT) technique. The Reweighted Zero Attraction Mixed Norm LMS (RZA-MNLMS) algorithm estimates the weight component relating to the load, used to estimate the total active weight required for generating gating signals for voltage source converter (VSC). The VSC provides compensation for varying solar insolation and unbalanced non-linear load conditions at the point of common connection, resulting in load-balancing and harmonics compensation along with unity power factor operation. The performance of the suggested control is studied by developing a simulation model in MATLAB Simulink. The simulated model shows satisfactory performance under several abnormal conditions.

Shipboard microgrids must have adequate protection schemes to be more reliable, provide the ability to prevent the spread of outages, and sustain continuous service to customers. The intelligent distance relay that is presented in this paper provides such an adequate scheme. The relay is performed by an Intelligent Electronic Device (IED) based on the IEC61850 communication network. This relay solves a problem that exists in the conventional distance relays of not protecting the whole line instantaneously. The proposed relay is based on a distance protection scheme that has two stages. Firstly, the fault is detected by applying the Fourier Transform algorithm to the voltage and current measurement while measuring the fault impedance, then comparing it with the reach point. Secondly, the fault location is identified by selecting the correct faulty zone. Then communication signals are sent between the relays based on IEC61850 to determine the appropriate time for isolating the fault. A 550 V DC zonal shipboard microgrid is simulated in MATLAB/SIMULINK environment to apply such a technique. The results prove the accuracy and efficiency of the proposed relay in protecting the whole line.

Recently, with the rapid adoption of electric vehicles (EVs) for modern transportation systems, an accurate forecasting of speed and torque is an utmost priority. As permanent magnet synchronous motors (PMSM) are an integral part of such EVs, hence this work has undertaken an effective forecasting of speed and torque of such motors. To showcase the efficacy of the proposed deep learning architecture for an effective speed and torque forecasting policy, this work adopts the dataset as formulated by University of Paderborn incorporating the effects of various factors like ambient temperature, coolant temperature, stator temperature etc. Gaussian copula based synthetic data generation have been used in this paper which effectively showcases an enhancement in model performance. This work shows a critical comparison between the proposed deep learning architecture along with some machine learning models, which further promotes the efficacy of the proposed forecasting policy.

As the need for accurate readings from the usual digital meter is increased in undeveloped countries the importance to involve modern technologies in this kind of meter also increased. Therefore, a power line energy meter PLEM is proposed in this paper which describes the design and implementation of this project. PLEM depends on its idea on different parts (microcontroller/ Arduino, Ethernet shield, adapters, and simple SCADA system) to give the efficient reading for the power consumption that can be consumed from different buildings and send these readings over the transmission lines using power line adapters to the main building where controlling and examination of the data will be easier to make as an example to the ministry of electricity.

Indonesian people need to know about the calorie information of the street food. One of effective ways to get that is using image-based calorie estimation technologies. However, there are two limitations. First, the problem of occluded food and second is the low R Squared value in measurement using linear regression model with area feature. This research proposed the Mask R-CNN model for amodal instance segmentation task to get the complete object shape and multiple linear regression model with area, perimeter, length, and width to predict the food weight. This research proposed Indonesian street food dataset that has six classes. There are 1646 images of the dataset and total instance of each food are 644 bakwan, 812 bolu, 918 cireng, 679 serabi, 711 tahu, and 766 tempe. The number of data point in multiple linear regression model is 230 bakwan, 200 bolu, 250 cireng, 240 serabi, 230 tahu, and 230 tempe. The proposed multiple linear regression model has the highest R Squared score in all classes with the average R Squared 0.80425. Mask R-CNN ResNeXt-101-FPN in amodal instance segmentation task reaches the best F1 Score. In occluded scenario this model gets F1 Score 0.821 in IoU threshold 0.85. In non-occluded scenario the model gets F1 Score 0.994 in IoU threshold 0.9. Even though the F1 Score is high, there are some false detections and the bad segmentation quality. In calorie prediction, the proposed model is not reducing MAE score in some classes due to the segmentation quality and food characteristic.

Despite growing concerns about biodiversity loss and the scarcity of fossil fuels, alternative energy sources are expected to take the lead in the world's energy landscape in the future. CHP systems (combined heat and power) combine electricity and heat energy into a single unit, increasing overall efficiency and lowering carbon emissions. CHPED (combined heat and power economic dispatch) problems are regarded as a difficult and nonlinear power system engineering challenge. Many solutions to this difficult problem have been proposed in recent years. In this article, the author proposes a new optimization algorithm. The Rao-I algorithm, which is metaphor-free and algorithm-specific, is used to solve the CHPED problem. The algorithm is tested on two different systems, and the results are compared to those of other well-known techniques to demonstrate that it is superior at dealing with real-time problems.

The algorithm is tested on two different systems, and the results are compared to those of other well-known techniques to demonstrate that it is superior at dealing with real-time problems.","PeriodicalId":283298,"journal":{"name":"2022 Second International Conference on Power, Control and Computing Technologies (ICPC2T)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134296937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
