The interest in electric vehicles (EVs) is rapidly increasing, and the upward trend seems to continue also in the future. As a result of the increasing energy consumption, the grid infrastructure has to be developed further, and moreover, it is necessary to analyze the network effects of the electric vehicle charging. In this paper, the challenge is approached by an actual case area in Finland and simulated EV traffic. The data used in the simulation are collected by measuring the traffic flow on the road leading to the case area. The objective of the paper is to demonstrate how the grid effects of large-scale electrification of transportation can be addressed, and what data are required to assess the additional charging load in a feasible manner. The data are processed by applying the Monte-Carlo method, and also a sensitivity analysis is performed.

This paper presents an approach that could be adopted as part of electrification strategies in developing countries. It makes use of microgrid designs which can be expanded and replicated in a modular fashion across wide geographic areas. The process of designing such a system is demonstrated with a case study in the state of Bihar in India. Results from the case study allow the costs of electrification by microgrids to be compared with those of extending the grid, and minimum distances from the grid where microgrid systems would be financially preferable to be determined. Taking into consideration the additional benefits offered by microgrid systems such as the ability to provide a highly reliable electricity supply, reduce transmission losses, expand the grid with smart features and facilitate the integration of renewable energies, it presents a convincing alternative to existing electrification strategies in developing countries.

Coordinating independent distributed generators 协调独立的分布式发电机
Pub Date : 2012-10-01 DOI: 10.1109/ISGTEurope.2012.6465735

Developers of distributed generator schemes often wish to increase the size of their generators, in order to make their projects more economically attractive. This work reported the coordination of the operation of independent distributed generators connected to the same circuit, so as to maximise the amount of electrical energy they deliver without exceeding the power limit of that circuit. An Aggregator, owned by the generators, schedules the generators that can be dispatched in times of reduced output of the other generation. The coordination leads to an additional income from the surplus of electrical energy that is able to be produced. The Aggregator runs a cooperative game with transferable utility to allocate this amount, considering the electrical power produced and the type of each generator. The results of a numerical example showed that all generators have an economic incentive to operate in a coordinated manner.
分布式发电方案的开发人员通常希望增加发电机的规模,以使他们的项目更具经济吸引力。这项工作报告了连接到同一电路的独立分布式发电机的协调运行,以便在不超过该电路功率限制的情况下最大限度地提供电能。由发电机拥有的聚合器调度在其他发电机输出减少时可以调度的发电机。这种协调可以从能够生产的剩余电能中获得额外的收入。考虑到产生的电力和每个发电机的类型,聚合器运行一个具有可转移效用的合作博弈来分配这个数量。数值算例结果表明,各发电机组具有协同运行的经济激励。

The hybrid wind-photovoltaic Power Park proposed in this paper is designed to perform multiple tasks while using renewable energies as the principle resources. Even though the renewable energy sources are intermittent and volatile, thanks to the battery energy storage system integrated in the Power Park, it is possible to attain deterministic power exchanges with the grid by an optimized scheduling and online operation strategy. Battery storage is integrated in the Power Park for renewable energy management, providing uninterruptible power supply, probably deferring some network upgrades, fast charging of electrical vehicles, and enhancing the value of the electricity generated by time-shifting delivery to the grid in a smart grid environment. In this paper, it is shown that the Power Park can be scheduled optimally for the mentioned multiple applications. An optimized scheduling program for the designed Power Park is formulated. An online scheduling strategy for the Power Park is also developed. Numerical results justify effectiveness of the developed methods.
本文提出的混合风-光伏发电园区以可再生能源为主要资源,同时兼顾多种任务。尽管可再生能源具有间歇性和不稳定性,但由于电力园区集成了电池储能系统,通过优化调度和在线运行策略,可以实现与电网的确定性电力交换。电池存储集成在电力园区用于可再生能源管理,提供不间断电力供应,可能推迟一些网络升级,电动汽车快速充电,并在智能电网环境中通过时变输送到电网来提高电力的价值。本文的研究表明,对于上述多种应用,电力园区可以进行最优调度。对设计的电力园区制定了优化调度方案。提出了电力园区在线调度策略。数值结果证明了所提出方法的有效性。

Under smart grid environment, islanding detection plays an important role in reliable operation of distributed generation (DG) units. In this paper an intelligent-based islanding detection algorithm for PV and DFIG units is proposed. Decision tree algorithm is used to classify islanding detection instances. This algorithm is rapid, simple, intelligible and easy to interpret. The error rate of this method is reduced by Adaptive Boosting (AdaBoost) technique. The proposed method is tested on a distribution system including PV, DFIG and synchronous generator. Probable events in the system are simulated under diverse operating states to generate classification data set. First and second order derivatives of locally measured electrical parameters are used for construction of 16-dimensional instances. The results indicate that Adaboost technique yields improved islanding detection accuracy. This algorithm is capable of detecting islanding phenomenon under operating states with negligible power mismatch.

The increasing installation of decentralized generators at the low voltage level is rendered difficult through the lack of monitoring and control possibilities at this level. The operation of distribution grids therefore needs to be extended in order to include this grid section. This paper presents a new control strategy based on agents which allows for the decentralized and coordinated management of generators, storage and loads. To implement this strategy, this work introduces distributed automation algorithms which are studied using the electric grid simulation software DIgSILENT Power Factory extended with an external Java/C++ development interface. The algorithms are developed and tested using a steady-state distributed simulation, and first results thereof are presented.

The development of ICT-Architectures for Smart Grids needs to regard requirements from multiple sources. These sources outline architectural viewpoints regarding domains, functionalities, and cross cutting issues like interoperability or security. A reference architecture is developed in context of the European Smart Grid Mandate M/490 which proposes a structure of interoperability layers, domains and zones, called the Smart Grid Architectural Model (SGAM). Such high-level reference architectures are not directly applicable within enterprises due to the differences in focus. Yet, the SGAM-structure may be used to transfer the concepts of the architecture into the enterprise context. For this purpose the methodological framework proposed in this contribution integrates the authors' research approaches. These provide integrated building blocks for enterprise-specific Smart Grid ICT-Architecture development, using the SGAM as the underlying structure.

Load frequency control using distributed batteries on the demand side with communication characteristics 负载频率控制采用需求侧具有通信特性的分布式蓄电池
Pub Date : 2012-10-01 DOI: 10.1109/ISGTEurope.2012.6465886

There has been a rapid expansion of renewable energy such as wind power and solar power in recent years. However, when the generated power flows into a power system the frequency fluctuation occurs by the unbalance of power supply and demand is concerned since the output of wind power or solar power changes every moment. Therefore, this paper presents a new frequency control method of the power grid with a large integration of the renewable energy based generations assuming that distributed batteries are introduced to the demand side. The influence of the characteristics of the information and communication technology on the matching of the power supply and demand is verified in case that the batteries are controlled by the signals sent from the grid side.
近年来,风能和太阳能等可再生能源的发展迅速。然而,当产生的电能进入电力系统时,由于风电或太阳能的输出是随时变化的,因此涉及到由于电力供需不平衡而引起的频率波动。因此,本文提出了一种新的基于可再生能源的大集成电网的频率控制方法,假设在需求侧引入分布式电池。以电网侧发出的信号控制蓄电池为例,验证了信息通信技术特性对供需匹配的影响。

However, when the generated power flows into a power system the frequency fluctuation occurs by the unbalance of power supply and demand is concerned since the output of wind power or solar power changes every moment. Therefore, this paper presents a new frequency control method of the power grid with a large integration of the renewable energy based generations assuming that distributed batteries are introduced to the demand side. The influence of the characteristics of the information and communication technology on the matching of the power supply and demand is verified in case that the batteries are controlled by the signals sent from the grid side.","PeriodicalId":244881,"journal":{"name":"2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128737973","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}
