Smart Grid collectively refers to various visions of how energy generation, distribution, and consumption should be managed to overcome many of the shortcomings of today's electricity grids and to sustain our ever more electricity dependent societies. One important enabling component of Smart Grid will be a fine-grained and reliable communications infrastructure that links together the many elements of the grid. Since by definition all these elements are connected to power lines, power line communications (PLC) technology is a natural candidate to build parts of such an infrastructure. In this paper, we consider the use of PLC in low- and medium-voltage distribution grids to connect network nodes (e.g., meters, actuators, sensors) through multihop transmission. In particular, we address the problem of routing of unicast messages making use of the stationarity of nodes. To this end, we motivate and investigate the application of geographic routing protocols and gauge their performance with respect to energy consumption and transmission delay.

In this paper, we propose a distributed agent based supervisory scheme to make Zone 3 relays robust to hidden failure induced tripping, facilitated by the communication network -- soon to become an integral parts of the smart grid. Possible elimination of Zone 3 relays (remote backup protection) has been studied in the recent past and these remote backup relays have been adjudged to be essential for power system protection [23]. Even though Zone 3 relays are often overly sensitive to remote line overloading, and are known to cause unwarranted trips during cascading failure scenarios, they are prescribed as acceptable means for remote backup. Therefore, providing robustness to Zone 3 relays to minimize the risk of erroneous trips, especially when hidden failures [10, 1] make them vulnerable to over reaction, is an important problem. In our scheme, a synchronous grid is populated with agents at each relay, and an agent hierarchy is maintained in master/slave relationship. The communication established between relay agents decreases the probability of erroneous Zone 3 trips thereby preventing them from aggravating cascading failure scenarios, and reducing the probability of cascading blackouts. Unlike other agent based relay proposals, ours is a nonintrusive approach.

Secure system state estimation is an important issue in smart grid to assure the reliability and security. In this paper, the case of a single observation station and Gaussian noise communication channel with an eavesdropper is considered. The channel capacity requirement is studied from the information theoretic perspective. The smart grid is modeled as a linear dynamic system. Then, the channel capacity requirement is studied for the state estimation of general linear dynamic systems and then applied in the system state estimation in smart grid. Numerical simulations are used to evaluate the capacity requirement in typical configurations of smart grid.

Wireless Sensor Networks and Control Systems are an essential part of the Smart Grid. We consider the problem of performing control over large complex networked systems with packet drops. More specifically, we are interested in improving the performance of the regulation of control loops when the communication is made over low-cost wireless networks. In control over wireless networks it is common to use Contention-Free (CF) schemes where no losses occur with the price of low scalability and complicated scheduling policies. In this work we propose a hybrid MAC and control architecture, where a small number of control loops with high demand of attention are scheduled in a CF scheme and well regulated loops are scheduled in a lossy, asynchronous and highly scalable, Contention-Access (CA) scheme. We model and analyze the performance of such system with Markov Jump Linear System (MJLS) tools and compare it with other architecture types. Performance is evaluated using a quadratic cost function of the state.
无线传感器网络和控制系统是智能电网的重要组成部分。我们考虑对具有丢包的大型复杂网络系统进行控制的问题。更具体地说，我们感兴趣的是在低成本无线网络上进行通信时提高控制回路的调节性能。在对无线网络的控制中，通常使用无争用(CF)方案，这种方案不会发生损失，但代价是低可伸缩性和复杂的调度策略。在这项工作中，我们提出了一种混合MAC和控制架构，其中在CF方案中调度少量具有高关注需求的控制环路，而在损耗，异步和高度可扩展的争用访问(CA)方案中调度良好的调控环路。我们用Markov Jump Linear system (MJLS)工具对该系统的性能进行建模和分析，并将其与其他架构类型进行比较。使用状态的二次代价函数来评估性能。

In this paper, we consider a smart power infrastructure, where several subscribers share a common energy source. Each subscriber is equipped with an energy consumption controller (ECC) unit as part of its smart meter. Each smart meter is connected to not only the power grid but also a communication infrastructure such as a local area network. This allows two-way communication among smart meters. Considering the importance of energy pricing as an essential tool to develop efficient demand side management strategies, we propose a novel real-time pricing algorithm for the future smart grid. We focus on the interactions between the smart meters and the energy provider through the exchange of control messages which contain subscribers' energy consumption and the real-time price information. First, we analytically model the subscribers' preferences and their energy consumption patterns in form of carefully selected utility functions based on concepts from microeconomics. Second, we propose a distributed algorithm which automatically manages the interactions among the ECC units at the smart meters and the energy provider. The algorithm finds the optimal energy consumption levels for each subscriber to maximize the aggregate utility of all subscribers in the system in a fair and efficient fashion. Finally, we show that the energy provider can encourage some desirable consumption patterns among the subscribers by means of the proposed real-time pricing interactions. Simulation results confirm that the proposed distributed algorithm can potentially benefit both subscribers and the energy provider.

The harmonization of CIM (IEC 61968/61970) and IEC 61850 standards is a major issue in the interoperability between smart grid devices, systems and applications. This paper describes how Ontology Matching methods, mainly developed for the Semantic Web, can be employed to solve the problems or mismatches that appear in this harmonization. The paper also includes a description of the ESODAT software tool, which processes OWL alignments to translate configuration files from one of the standards (CIM or IEC 61850) to the other one. The tests carried out with this tool proved its ability to solve mismatches that appear in the state of the art. Besides, the solution proposed in this work is based on open source resources and does not require any modification of the original standards.

Currently, several smart grid efforts in US and Europe are gaining momentum. Even if there are different focuses in US and Europe on what is known as the smart grid, all agree on the fact, that standardization is a key issue. Hence, a lot of studies and roadmaps pick standardization in the context of smart grids out as a central theme. The various approaches are concentrating on different core areas, depending on the circumstances in which they were elaborated. However, no overview aligning these approaches exists. This contribution takes all relevant approaches up to now into account, which give concrete recommendations for smart grid standards. The approaches will be aligned, and a set of core standards will be identified to point out the most important fields for future research and development. Furthermore, the IEC TC 57 Seamless Integration Architecture SIA will be introduced and extended by future standards, which were identified as core standards and existing work not yet included in the SIA.

The power outputs of non-conventional renewable sources are random and intermittent in nature. The integration of such sources in large numbers into existing power networks in the future could make the reliable and stable operation of power systems highly challenging. In this paper, the performance of a method based on balancing active power near real time, to reduce power fluctuations produced by renewable sources, is presented. The ability to exchange timely information and availability of adequate energy storage capacity are vital factors that determine the effectiveness of this method. Hence the performance, under varying communication delay and V2G vehicle pool size, of this method was evaluated by the authors. Three indices were defined and used to measure performance. The frequency of power balancing process was also varied during the study to accommodate longer information exchange delays. Results reveal that performance improves as communication delay and the period of control cycle are shortened. It was also observed that beyond a certain size of V2G pool, performance improvement reaches saturation. This indicates that, for a given system, there is a minimum V2G pool size requirement for studied method to deliver peak performance.

Whilst security is generally perceived as an important constituent of communication systems, this paper offers a viable security-communication-tradeoff particularly tailored to Advanced Metering Infrastructures (AMIs) in Smart Grid systems. These systems, often composed of embedded nodes with highly constrained resources, require e.g.~metering data to be delivered efficiently whilst neither jeopardizing communication nor security. Data aggregation is a natural choice in such settings, where the challenge is to facilitate per-hop as well as end-to-end security. The prime contribution of this paper is to propose a secure aggregation protocol that meets the requirements of Smart Grids, and to analyze its efficiency considering various system configurations as well as the impact of the wireless channel through packet error rates. Relying on analysis and corroborative simulations, unprecedented design guidelines are derived which determine the operational point beyond which aggregation is useful as well quantifying the superiority of our protocol w.r.t. non-aggregated solutions.

Dynamic energy pricing is a promising development that addresses the concern of finding an environmentally friendly solution to meeting energy needs of customers while minimizing their electrical energy bill. In this paper, we mathematically formulate the electrical energy bill minimization problem for cooperative networked consumers who have a single energy bill, such as those working in a commercial/industrial building. The idea is to schedule user requests for appliance use at different times during a fixed interval based on dynamic energy prices during that interval. Two different methods are presented to minimize the energy cost of such users under non-interruptible or interruptible jobs. The methods relay on a quasi-dynamic pricing function for unit of energy consumed, which comprises of a base price and a penalty term. The methods minimize the energy cost of the users while meeting all the scheduling constraints and heeding the pricing function. The proposed methods result in significant savings in the energy bill under different usage pricing, and scheduling constraints.
