Peer-to-peer (P2P) energy trading facilitates the trading of a prosumer's surplus generated energy from the Distributed Energy Resource (DER) to the neighbouring prosumer having an energy deficit. Its primary aim is to reduce consumers' energy prices, increase DER owners' revenue and incentivise them for energy trading. Mid market rate, supply demand ratio and bill sharing are the established pricing mechanisms in this paradigm. Despite having wide implementations of existing pricing mechanisms, they fail to provide fair and optimal energy prices. Also, they do not incorporate factors like participating prosumers' conflicting interests; innate human behaviour like fair, selfish, or greedy nature; and their contradictory trading strategies. Game theory determines energy prices by incorporating these factors. It reduces system costs and encourages prosumers to trade in the local electricity market. Hence, various game theoretic models have been proposed for different P2P energy trading mechanisms. However, a systematic study to comprehend the applicability of various models to this trading paradigm is necessitated. It is required with a view to identify and design appropriate price determination models for varying trading conditions. This review paper delivers an overview of P2P trading, fundamentals of game theory, models used for energy price determination and identification of further research directions implementing game theory in this energy trading.
点对点(P2P)能源交易促进了产消者从分布式能源(DER)中产生的剩余能量与具有能量赤字的相邻产消者的交易。其主要目标是降低消费者的能源价格,增加DER所有者的收入,并激励他们进行能源交易。市场中间价、供需比和账单分担是该模式下建立的定价机制。尽管广泛实施了现有的定价机制,但它们未能提供公平和最优的能源价格。此外,他们没有考虑到参与生产消费者的利益冲突等因素;人类天生的行为,如公平、自私或贪婪的天性;以及他们相互矛盾的交易策略。博弈论通过纳入这些因素来决定能源价格。它降低了系统成本,并鼓励消费者在当地电力市场进行交易。因此,针对不同的P2P能源交易机制,提出了不同的博弈论模型。然而,有必要进行系统的研究,以了解各种模型对这种交易范式的适用性。它的目的是为不同的交易条件确定和设计适当的价格确定模型。本文概述了P2P交易、博弈论的基本原理、用于能源价格确定的模型,并确定了在这种能源交易中实施博弈论的进一步研究方向。

Renewable energy (RE) penetration through the concept of microgrids improves the efficiency and dependability of the electrical system. Power electronic (PE) converters with effective control strategies result in a successful interface between RESs and the electrical grid which enables power sharing among RESs, loads and grid. This paper aims to give a comprehensive analysis of the power sharing and power balancing within AC-microgrid and also investigate the essential control strategies operated during islanded (IS) mode and grid-tied (GT) mode. The impact and function of control levels or controllers associated with a particular control strategy in the power management during IS and GT mode are carried out in MATLAB/Simulink environment and hardware in the loop (HiL) implementation (using RT-LAB and OP5600) considering an AC-microgrid configuration with solar photovoltaic (PV) and energy storage scheme (ESS). The outcomes from the analysis illustrate that the power sharing within AC-microgrid is greatly influenced by the selection of designed parameters and performance of the controllers. Also, suitable operation of the controllers ensures proper power balancing throughout the entire operational time in AC-microgrid. Therefore, utilization of the maximum generated power from RESs and accurate power balancing within AC-microgrid are ensured by the precise operation of the used controllers.
可再生能源(RE)通过微电网的概念渗透,提高了电力系统的效率和可靠性。电力电子(PE)变换器具有有效的控制策略,可以在RESs和电网之间建立成功的接口,从而实现RESs、负载和电网之间的电力共享。本文旨在全面分析交流微电网内的功率共享和功率均衡,并研究孤岛模式和并网模式下的基本控制策略。考虑到具有太阳能光伏(PV)和储能方案(ESS)的交流微电网配置,在MATLAB/Simulink环境和硬件在环(HiL)实现(使用RT-LAB和OP5600)中,在IS和GT模式下,与特定控制策略相关的控制电平或控制器在电源管理中的影响和功能。分析结果表明,设计参数的选择和控制器的性能对交流微电网内的功率共享有很大的影响。同时,控制器的合理运行保证了交流微电网在整个运行时间内的功率均衡。因此,通过所使用控制器的精确运行,保证了对RESs最大发电量的利用和交流微电网内准确的功率均衡。

In universal-line, AC-DC buck power factor correction (PFC) converters require high PF and less THD in input current. Due to pulsating input current in the conventional buck and quadratic buck converters, their PFC versions give poor PFC performance and demands increased input filter requirement. This paper introduces two switch-semi quadratic buck PFC converter in intermediate DC-DC conversion state. The salient features of this PFC topology are high step-down gain, smother input current waveform with less ripple content. The average current controlled method is employed, and converter is operated in CCM mode. To verify the effectiveness of this converter for PFC applications, simulations are performed for 110V, 50 Hz supply and for load of 24V,65W. The input current THD and PF are compared with the conventional buck PFC converter for identical input and output conditions.
在通用线路中,交直流降压功率因数校正(PFC)变换器需要高PF和低THD的输入电流。由于传统降压和二次降压变换器的输入电流存在脉动,其PFC版本的PFC性能较差,并且对输入滤波器的要求更高。介绍了两种处于中间DC-DC转换状态的开关-半二次降压PFC变换器。这种PFC拓扑结构的显著特点是降压增益高,输入电流波形平滑,纹波含量少。采用平均电流控制方法,变换器工作在CCM模式下。为了验证该转换器在PFC应用中的有效性,在110V, 50hz电源和24V,65W负载下进行了仿真。在相同的输入和输出条件下,与传统降压型PFC变换器的输入电流THD和PF进行了比较。

In this paper, we present a model for optimizing network routing in a geographic area. Our approach combines heuristic and graph theory techniques to find near-optimal solutions to the problem of connecting all users in the network. The model was implemented in a random scenario, and the results showed that it is effective at finding good solutions to this problem. This work is relevant for planners and designers who are working on network routing issues, as it provides a useful approach for finding solutions that are both efficient and effective. Overall, our model has the potential to aid in the design process for planning networks in a variety of different contexts.

The continuous efforts to enhance transparency and digitalization of the low-voltage grid will impact grid operation and the load distribution of its components. The impact of an increasing share of flexible and controllable devices in the residential sector in conjunction with an ongoing introduction of modern high power devices has not been devoted the attention this topic deserves in the literature. The major share in literature deals with a maximum extend in flexible and controllable devices. This paper expands the agility factor-based method to a wider set of Demand Response programs and analyses the ramp-up of modern newly introduced devices in the residential sector in a reference grid, based on grid data of the city of Hamburg, Germany. Due to this method the loading development can be evaluated and critical grid sections can be selected for further analysis. Additionally, the dynamic grid connection point power limitation based on the agility factor method is introduced as Demand Response program and a possible countermeasure against energy paybacks following variable energy pricing schemes.
不断提高低压电网的透明度和数字化,将对电网运行和各组成部分的负荷分布产生影响。随着现代大功率器件的不断引入,柔性和可控器件在住宅领域的份额越来越大,这一主题在文献中没有得到应有的关注。文学的主要部分是最大限度地运用灵活可控的手段。本文将基于敏捷性因素的方法扩展到更广泛的需求响应计划,并基于德国汉堡市的网格数据,在参考网格中分析了住宅部门中现代新引入设备的增加情况。由于这种方法可以评估荷载的发展,并可以选择关键的网格截面进行进一步的分析。在此基础上,提出了基于敏捷系数法的动态并网点功率限制作为一种需求响应方案,并提出了一种针对可变电价方案下能源回报的可能对策。

Being the innovation, machine learning has indisputably dominated energy consumption prediction from home to the industry all over the world. Many approaches have been acknowledged throughout the past decade to upgrade the energy demand which is not an alien to Bangladesh. Moreover, the energy consumption has been classified according to the convenience for both builders as well as end-users. As a consequence, such analysis has led to short, medium, and long-term consumption concept in forecasting of energy. This paper explores the energy demand analysis using conventional machine learning models for medium-term energy consumption. It also reviews the detail possibilities of energy consumption along with challenges. A forecast of power consumption based on a dataset of a residential apartment for a year has been presented with related parameters and results. Even an anticipated energy management plan has been discussed for Bangladesh.
作为一项创新,机器学习在全球范围内从家庭到行业的能耗预测中占据着无可争议的主导地位。在过去的十年中,许多方法已经得到承认,以提高能源需求,这对孟加拉国来说并不陌生。此外,根据对建筑商和最终用户的便利程度对能耗进行了分类。因此,这种分析导致了能源预测中的短期、中期和长期消费概念。本文探讨了利用传统的机器学习模型对中期能源消耗进行能源需求分析。它还详细回顾了能源消耗的可能性以及挑战。本文以某住宅楼为例,对某住宅楼一年的用电量进行了预测,并给出了相关参数和结果。孟加拉国甚至已经讨论了一项预期的能源管理计划。

Power electronic converters are extensively used in AC/DC, DC/DC, and DC/AC conversion in renewable energy utilization. To protect the equipment in the converter circuits from overvoltages and over currents, surge arresters are placed at various locations for the protection in the converter station. Based on the location, the surge arresters experience particular kinds of complex waveforms as per IEC 60099-9 standard. An automated source that can generate the required waveforms and have better safety features is the need for the proper evaluation of the surge arresters. In the present work, an effort is made to develop an arbitrary waveform generator and a voltage amplifier, wherein the amplifier is developed for complex waveforms for the voltage level of 100V.

This work presents the performance evaluation of a Gallium Nitride (GaN) device for an Electronic Power Conditioner (EPC) that is basically used for powering up amplifiers for satellite and communication systems. From decades silicon (Si) based MOSFETs have been employed for converters used in high and medium-switched mode power supplies. Since Si devices have reached their theoretical device limitation, GaN provides a quite suitable alternative to these devices. In this work, initially, the performance of the basic converters has been verified for GaN devices in comparison with Si devices, and then after simple validation, the focus has been shifted to a much more advanced converter like Phase Shift Full Bridge Converter (PSFBC) which is the main component in most of the EPCs. Moreover, there has been discussion in detail about the thermal performance of the GaN device when it is implemented on a Printed Circuit Board (PCB).
本工作介绍了用于电子电源调节器(EPC)的氮化镓(GaN)器件的性能评估,该器件主要用于为卫星和通信系统的放大器供电。几十年来,硅(Si)基mosfet已被用于高、中开关模式电源的变换器。由于硅器件已经达到了它们的理论器件限制,GaN提供了一个非常合适的替代这些器件。在这项工作中,首先,与Si器件相比,已经验证了GaN器件的基本转换器的性能,然后经过简单的验证,重点已经转移到更先进的转换器,如移相全桥转换器(PSFBC),这是大多数epc的主要组件。此外,还详细讨论了GaN器件在印刷电路板(PCB)上实现时的热性能。
