Due to the increase of energy demand by rapid growth of population, it is necessary to modernize the power grid with improved power quality, such that the energy converted by solar PV (SPV) can be transmitted and stored as the excess amount of power in terms of batteries to use at peak load demand. The batteries of the EVs charge at a low level of demand and discharged at peak demand. The EVs can function both as a load and an energy supplier to the SG. The simulation results demonstrate the functioning of interfaced smart G2V system by observing and improving the factors such as power factor, power regulation and elimination of harmonics by constructing a power electronic network which can perform bidirectional power flow and balancing the network using MATLAB/Simulink software. Subsequentially, the improvement of power quality of the integrated system by analyzing power compensation, voltage regulation and harmonics mitigation of the integration system has been examined in detail.","PeriodicalId":129707,"journal":{"name":"2022 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130100428","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}

The temporal fusion transformers (TFT) approach is an attention-based deep learning model with interpretable insights into temporal dynamics. The sequence-to-sequence model processes the historical and future covariates to enhance the forecasting performance. Gated Residual Network (GRN) is applied to drop out unnecessary information and improve efficiency. The proposed method is tested on anonymized data from a university campus.

A typical grid connected solar PV power generation plant consists of the PV array and a DC – DC boost converter. The inductor value in a DC – DC boost converter depends on the input voltage, output voltage, switching frequency and the allowable inductor current ripple. Whereas, size of the capacitor is determined by, the allowable voltage ripple, switching frequency and the output current. The input voltage in a PV system changes with temperature conditions, inductor current and output current change with irradiance levels as well as with variations in load. Therefore, in this research work, a simple and explicit method of designing and analyzing the performance of a DC–DC boost converter based on monthly average values of solar irradiances & temperatures has been presented and through simulation results it has been proved that the designed boost converter integrated with P & O MPPT algorithm & INC MPPT algorithm, yields the desired yearly performance. Monthly average values have been selected rather than seasonal averages with the aim of achieving greater accuracy in the calculated values of inductor and capacitor. A 1.248 MW array has been considered for design of the boost converter.","PeriodicalId":129707,"journal":{"name":"2022 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126790852","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}

This paper examines a LEM of 100 participants from an Australian town, comprising three distinct players; consumers, prosumers with solar photovoltaics (PVs), and prosumers with solar PVs and BESS. BESS investment returns are calculated based on four capital budgeting techniques. Because there is an additional optimised revenue stream through peer-to-peer (P2P) trading-based LEM, the investment returns for residential BESS are better. Better returns mean that LEMs could encourage people to buy and install more BESS. The study finds the investment returns of residential BESS, and performs comparative analysis to prove LEM is a better solution to improve returns. Additionally, the results also show that participants with BESS get maximum reduction in their cost of energy usage.","PeriodicalId":129707,"journal":{"name":"2022 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842616","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}

The transformerless converter operation with high gain makes the converter appropriate for integrating photovoltaic (PV) power to isolated DC microgrid. The common intermediate capacitor reduces the component count and voltage stress on the input side switches; thus, achieving high efficiency at a lower cost. The Proposed interleaved quadratic boost converter is ideal for PV power extraction as it exhibits no input current ripple and has high input current handling capability. A 1000 W two-phase interleaved prototype of the converter is designed, developed, and analyzed to verify its working principle.

The rule-based discriminative approach is adopted to efficiently identify system faults and their type without the need for historical data or specific physical models. The unmanned ship IPS is modeled on the RTLAB hardware-in-the-loop simulation platform, and the DT system is established on Simulink.

In order to ensure that bridge arm current does not exceed the bearing range of modular multilevel converter (MMC) switching devices under AC fault ride through and other scenarios, MMC high voltage direct current (HVDC) system projects are equipped with temporary block (TB) function, IGBTs are protected by suspending the trigger pulse before bridge arm current reaches the maximum safe current of the switch. The structure of high side and low side valve group (VG) in series are adopted in ultra high voltage direct current (UHVDC) system. For line commuted converter (LCC) UHVDC system, the converter is current source type, During normal operation, there is no need to control the voltage balance between high side and low side VG, and after one VG is disturbed by commutation failure, the impact on another VG is relatively small. For MMC-UHVDC system, the converter is voltage source type, during normal operation, the voltage balance between high side and low side VG should be controlled. When a transient disturbance such as AC fault occurs, if one VG is temporary blocked due to bridge arm over-current, and another VG is not temporary blocked or the time of temporary blocked is later, the VG blocked first may tripped due to sub-module (SM) overall over-voltage or bridge arm over-current, and the scope of the accident is expanded, which is not conducive to the flexible and reliable operation of MMC-UHVDC. Therefore, the impact of non synchronous temporary block of MMC-UHVDC VGs is firstly analyzed in this paper, and then synchronous temporary block (STB) function between VGs is proposed, and the hardware interface scheme, STB signal sending and receiving logic, enable conditions and other aspects between VGs are elaborated. Finally, taking kunliulong project, the world’s first multi terminal Hybrid (MTH) UHVDC project, as the application background, a real-time simulation (RTS) test system for control and protection (C&P) system is established. The enable conditions of the STB function are verified. The response and dynamic characteristics of the system under abnormal measurement of bridge arm current, AC fault and VG short circuit fault when enabling or disabling STB function are compared. The simulation results show that the reliability of MMC-UHVDC can be improved by enabling STB function.","PeriodicalId":129707,"journal":{"name":"2022 IEEE Sustainable Power and Energy Conference (iSPEC)","volume":"383 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114000429","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}

Then, the resilience assessment metrics are constructed by analyzing the whole process of the system resilience under an ice disaster. On this basis, a resilience enhancement method under the ice disaster is proposed by using the transfer entropy of power flow to screen the lines that need deicing.
