The use of matrix converters (MC) as interfaces between the grid and the traditional doubly fed induction generators (DFIG) in wind power applications introduces high harmonic frequencies of which traditional passive filters may not be suitable for attenuation. This paper analyses the harmonic frequencies generated by the MC and proposes a hybrid harmonic filter (HHF) for harmonic and power factor compensation in the grid side of the MC. The HHF achieved 1.02% THD% of the fundamental 50Hz with little to no impact to the dynamic stability of the MC. The results were simulated and confirmed with MATLAB/Simulink simulation software.

In this paper, we investigate how experts evaluate peer-to-peer (P2P), community self-consumption (CSC), and transactive energy (TE) market models compared to a traditional market model. The different models are evaluated on their capacities to generate different types of values in the electricity market. To facilitate the evaluations, we adopted the Analytic Hierarchy Process (AHP). The AHP is a quantitative multiple criteria decision-making tool facilitating experts to make a difficult choice between various options along a set of distinct evaluation criteria by a sequence of pairwise comparisons. So far, the AHP has not yet been applied in the context of energy transaction markets. Results show that experts prefer the community self-consumption and transactive energy market models because they might be most successful in generating green energy. These results help policy makers to better understand the heterogeneous capacities of the market models.
在本文中,我们研究了专家如何评估点对点(P2P)、社区自消费(CSC)和交易能源(TE)市场模型与传统市场模型的比较。评估了不同的模型在电力市场上产生不同类型价值的能力。为了便于评价,我们采用了层次分析法(AHP)。AHP是一种定量的多标准决策工具,通过一系列的两两比较,帮助专家在一系列不同的评估标准中做出困难的选择。到目前为止,AHP还没有在能源交易市场中得到应用。结果表明,专家们更倾向于社区自用和交易能源市场模式,因为它们可能在产生绿色能源方面最成功。这些结果有助于决策者更好地理解市场模型的异质性能力。

The complexity of energy scheduling problems is increasing due to the energy transition. In recent research, Machine Learning (ML) has shown potential to contribute to the methodology for executing these tasks efficiently and reliably in future. This paper develops and compares three approaches for predicting binary decisions in Unit Commitment problems with network constraints: Two ML predictors using Random Forests and Graph Neural Networks are contrasted with a rule-based approach. On large datasets of realistic synthetic Unit Commitment problems, the performance criteria that need to be met for successful real-word application are evaluated: What is the speedup potential of using the predictions in the process? What is the risk of losing optimality or even feasibility? And what are the generalization capabilities of the predictors? We find that all three approaches have promising potential, each approach having its own pros and cons.

In this paper, the analysis of peer-to-peer energy trading with smart contracts, which are applications run on blockchains, is presented. The software architecture and algorithm of the smart contracts that run on the Ethereum Virtual Machine are mentioned. The smart contracts are applied transactions that guarantee the information of both parties in a peer-to-peer transmission and are verified by the logic structure that operates within itself and do not cause any vulnerabilities in the system. In addition, a software background with an instrument panel in the user interface and offering prices within the framework of the supply-demand relationship is presented. In addition to these, the paper aims to promote decentralisation by integrating renewable energy sources with the framework of peer-to-peer trading methods on a Blockchain.

Cold countries with low irradiance values have typically used utility grid to support solar PV systems. However, the extended option is facing new challenges: the electricity tariffs increase and the expected high penetration of EVs, which can increase the pressure on the grid. In this research, a prototype simulation model of a solar PV-batteries-grid HRES to cover recharge of EVs was developed. The system was simulated in MATLAB®, with a control algorithm based on power balance between EVs load demand-solar PV generation, and the state of charge (SOC) of the batteries. The results indicate the suitability of the simulation model. It can select the appropriate support system according to the control algorithm. Moreover, the two scenarios presented for the case study reflect the importance of the initial SOC, since it will directly affect the availability of batteries for covering electricity shortfalls.
辐照度低的寒冷国家通常使用公用电网来支持太阳能光伏系统。然而,延长选项正面临新的挑战:电价上涨和电动汽车的预期高渗透率,这可能会增加电网的压力。在本研究中,建立了覆盖电动汽车充电的太阳能光伏-电池-电网HRES原型仿真模型。在MATLAB®中对系统进行仿真,采用基于电动汽车负载需求-太阳能光伏发电和电池荷电状态(SOC)之间功率平衡的控制算法。结果表明了该仿真模型的适用性。它可以根据控制算法选择合适的支持系统。此外,为案例研究提出的两种情况反映了初始SOC的重要性,因为它将直接影响电池的可用性,以弥补电力短缺。

Electric Vehicle (EV) charging is classified into two major categories, depending on the type of chargers used. These are referred to as Alternating Current (AC) and Direct Current (DC) chargers. EVs' batteries are charged by an external source of electricity, such as the grid. Achieving the required charging voltage, charging current, and the charging power for the EV batteries requires power electronic interfaced technologies. AC charging requires an AC to DC converter, which is usually performed within the vehicle itself. DC charging, on the other hand, utilises an off-board converter to get DC power. The dynamic behaviour of power systems has changed drastically due to the increased usage of power electronic interfaced technologies. This paper presents different EV integration scenarios into a Nigerian distribution network feeder that serves both residential and commercial customers. The PSCADIEMTDC simulation software is used to investigate the impacts of different charger topologies from a grid perspective. The sizing of an appropriate filter is also proposed to help mitigate harmonic distortion introduced by various battery chargers in the network. The paper results bolster confidence in the ability of EVs and associated charging methods to be incorporated in different nations’ distribution network feeders via appropriate technologies while maintaining grid safety and reliability.
根据所使用的充电器类型,电动汽车(EV)充电分为两大类。它们被称为交流(AC)和直流(DC)充电器。电动汽车的电池由外部电源充电,比如电网。实现电动汽车电池所需的充电电压、充电电流和充电功率需要电力电子接口技术。交流充电需要一个交直流转换器,这通常在车辆内部进行。另一方面,直流充电利用板外转换器获得直流电源。由于电力电子接口技术的使用增加,电力系统的动态行为发生了巨大的变化。本文介绍了不同的电动汽车集成到尼日利亚的配电网络馈线,为住宅和商业客户提供服务。使用PSCADIEMTDC仿真软件从电网角度研究不同充电器拓扑结构的影响。本文还提出了合适滤波器的尺寸,以帮助减轻网络中各种电池充电器带来的谐波失真。本文的研究结果增强了人们对电动汽车和相关充电方法的信心,这些方法可以通过适当的技术纳入不同国家的配电网馈线,同时保持电网的安全性和可靠性。

This paper presents the developed methodology to determine the most optimal solution to generate electricity in Saudi Arabia by conventional power generators. The analysis will consider all parameters and factors in the country that influence the decision-making process such as efficiency, cost, water utilization, greenhouse gas (GHG) emissions, and land use. The methodology utilizes the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which is one of the Multicriteria Decision Analysis (MCDA) methods. This approach can support and assist power generation planning firms to adopt the most accurate generation system anywhere in the world. In this paper, the methodology is applied to Saudi Arabia, as the country has ambitious targets of relying more on environmentally friendly generation; such as renewables, natural gas turbines and nuclear power plants.

This paper suggests the implementation of the partial power converter for PV power processing instead of full power converter for better system efficiency and robustness. Processing a percentage of the total power, instead of processing the full power, improves system efficiency and reduces system cost and size. In this paper, an input parallel output series (PISO) buck-boost partial power converter is presented. The first stage of the system is controlled to ensure that PV panels are operating at the maximum power (MP). And the second resonant stage is controlled to fix the dc-bus voltage. Although the system has five-switches, four of them are operating in zero voltage and current switching, to eliminate switching losses of the system. Converter sharing percentage is adjusted to ensure optimum operation of the complete PV system. System analysis and simulation are demonstrated through the manuscript. Experimental and more comparative analysis will be presented in the final version.
为了提高系统的效率和鲁棒性,建议采用部分功率变换器代替全功率变换器进行光伏发电处理。处理总功率的一部分,而不是处理全部功率,提高了系统效率,降低了系统成本和尺寸。本文提出了一种输入并联输出串联(PISO)降压升压部分功率变换器。控制系统的第一阶段,以确保光伏板在最大功率(MP)下运行。控制第二谐振级固定直流母线电压。虽然系统有5个开关,但其中4个开关工作在零电压和零电流开关,以消除系统的开关损耗。调整转换器共享百分比以确保整个光伏系统的最佳运行。通过论文对系统进行了分析和仿真。实验和更多的比较分析将在最终版本中呈现。

The first stage of the system is controlled to ensure that PV panels are operating at the maximum power (MP). And the second resonant stage is controlled to fix the dc-bus voltage. Although the system has five-switches, four of them are operating in zero voltage and current switching, to eliminate switching losses of the system. Converter sharing percentage is adjusted to ensure optimum operation of the complete PV system. System analysis and simulation are demonstrated through the manuscript. Experimental and more comparative analysis will be presented in the final version.","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116312060","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 study describes the developed method intended for dynamic modelling of a country’s economic and demographic processes related to the transport market, vehicle and fuel consumption. The method of prediction used in this model is artificial life. The situation of energy consumption for motor transport in Latvia is considered. The model being developed examines the factors influencing energy consumption in road transport. The model takes into account the influence of various factors on energy consumption in transport population, income rates, number of vehicles, countries of the region, taxes, economic factors. The energy forecasting model focuses on a set of planning and forecasting practices that take into account micro- and macroeconomic variables. Since forecasting is a scientific study of specific development prospects based on a system of qualitative and quantitative research aimed at identifying trends in the development of desired indicators, it is necessary to compile statistics on micro and macroeconomics. Data from various fields related to various scopes of human activity have been collected and analysed.
这项研究描述了旨在对一国与运输市场、车辆和燃料消耗有关的经济和人口进程进行动态建模的已开发方法。在这个模型中使用的预测方法是人工生命。考虑了拉脱维亚汽车运输的能源消耗情况。正在开发的模型考察了道路运输中影响能源消耗的因素。该模型考虑了各种因素对交通能源消耗的影响,人口、收入率、车辆数量、地区国家、税收、经济因素。能源预测模型侧重于考虑到微观和宏观经济变量的一套规划和预测实践。由于预测是根据一套定性和定量研究系统对具体发展前景进行的科学研究,目的是查明制订所需指标的趋势,因此有必要编制关于微观和宏观经济学的统计数字。已经收集和分析了与各种人类活动范围有关的各个领域的数据。
