It is envisioned that a fleet of electric vehicles may provide auxiliary means for frequency and voltage regulation to improve the power quality and the stability of the power grid. This emerging technology is especially important for microgrid because of the volatility of power generation and consumption in a microgrid due to its diverse and sometimes unpredictable power sources and distributed load. In this work, the intelligent electric vehicle charging control for reduced cost and improved stability of microgrid is formulated as a constrained optimization problem. In order to capture the uncertainties in a microgrid, a discrete-time Markov Decision Process is adopted to model the dynamics of the system. Value iteration and policy iteration are used to solve the problem, and simulation results indicate that the resulted action policy made state transitions towards the stable states, thus scheduled electric vehicle to provide auxiliary regulation services to stabilize the system.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"19 1","pages":"662-667"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83257490","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}

To confront this challenge, electric utilities and telecommunications operators have proposed the use of a hybrid wireless access network, referred to as a hybrid SG network, which is a combination of both public and private access networks. The public access network is leased by the electric utility from a telecommunications operator, where the network carries both Human-to-Human (H2H) communications traffic and SG communications traffic. On the contrary, the private access network is owned by the electric utility to exclusively deliver the SG communications traffic. However, a key issue in hybrid SG networks is how to efficiently partition the SG traffic onto public and private access networks. In this paper, we propose a unified analytical framework, based on a queuing system, to evaluate the performance of hybrid SG networks under different policies for the partitioning of the SG traffic. By using this framework, expressions for several performance metrics are derived and used to compare between two basic partitioning policies, referred to as load-based and traffic-based. The analytical framework is validated by simulations of a wireless network model using real-world SG traffic profiles from the Ausgrid Smart Grid Smart City project and shown to agree well with the simulations.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"6 1","pages":"380-385"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82044482","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}

However, there are currently no large communication networks using medium voltage power line communication. In this paper we evaluate the performance of the IPv6 routing protocol RPL designed for networks with low-power devices and lossy links on PLC links in a medium voltage scenario. For this purpose the embedded OS Contiki networking stack has been extended on the MAC and networking layer. To capture realistic conditions, we implemented a SINR (signal-to-noise+interference-ratio) model of the MV PLC channel for the COOJA network simulator. This enables us to investigate latency, success rate, control traffic for a partly meshed medium voltage grid simulation scenario based on the grid layout of a local utility. Thus we provide a benchmark to evaluate networking protocols for monitoring and control applications for smart grids. Based on the evaluation results, we can identify application scenarios where RPL is suitable as well as some of the systems's constraints and drawbacks.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"79 1","pages":"446-451"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81339708","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}

In this paper we consider the use of Smart Metering data for Distribution State Estimation (DSE), and compare the effectiveness of daily data collection strategy with a more frequent, half-hourly SM data collection strategy. We first assess the suitability of using the data for load forecasting at Low Voltage (LV) transformers, and then use the forecast for DSE. The outputs of DSE indicate a whole system's real-time status which can be used to make effective decisions for grid control. Our statistical test results show that the use of the half-hourly collected SM data significantly improves the load forecasting accuracy. However, the DSE results show that neither data collection strategy alone is sufficient to estimate a system's status accurately, and both require additional real-time measurements, with significantly fewer additional measurements points required if the data is collected half-hourly. This research offers a unique DSE perspective which will provide evidence towards a more comprehensive specification of the SM data collection frequency if it is to be used for smart grid operational support.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"23 1","pages":"517-522"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83569729","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}

At the same time, the control overhead in normal operation should be limited and not interfere with the data traffic. Hence the routing protocol for such networks has to trade-off these two conflicting goals. One of the candidate routing protocols for Smart Grid networks is the IETF IPv6 routing protocol RPL which was designed for low-power and lossy networks. It strives to consume little bandwidth and energy with its traffic overhead and to be under-reactive to network changes. This design choice was made because in many of the technologies envisioned for such networks the bandwidth is scarce and the link quality may vary. Fluctuations should not trigger unnecessary instabilities, thus the system was designed to have inertia before deciding to modify communication paths. However, this robustness is in direct conflict with the agility that is required for fast recovery in case of communication failures. In this article we investigate the behavior of the local repair failover mechanism, then we propose and evaluate simple options to minimize the recovery time.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"292 1","pages":"248-253"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86583503","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 uncertainty of the EV arrival, the intermittence of the renewable energy, and the variation of the grid power price are taken into account. In each period, the station determines the number of charging EVs during this period. Meanwhile, it also chooses the amount of renewables used for charging (the rest amount of energy will be purchased from the grid). The goal is to minimize the mean waiting time of EVs under the long-term constraint on the cost. We formulate a stochastic optimization problem, in which the charging EV number sequence and the allocated renewable energy sequence compose the two-dimensional optimization variable vector sequence, to investigate this scheduling problem. We derive the formal solution of the problem. Specifically, we prove that the optimal variable vector can be successively obtained: the optimal number of charging EVs is the solution of a reduced stochastic optimization problem and the greedy renewable energy allocation is optimal for given number of charging EVs. Finally, based on theoretical analysis, we propose two strategies for the problem and we investigate the proposed strategies numerically.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"20 1","pages":"596-601"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86633758","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}
