State estimators have conventionally filtered out so-called bad data or outliers, but in recent years a number of attacks and mitigation mechanisms have been proposed involving deliberate injection of bad data. In this paper, we introduce a constrained attack mechanism which will be feasible where the communication channel for measurements is authenticated and integrity-protected. We demonstrate that re-ordering of measurements is sufficient to cause errors in state estimation or preventing convergence and propose an algorithm to introduce such attacks. Based on this, we introduce two security metrics to quantify the effort required for sparse and minimum magnitude re-ordering attacks, respectively, in the form of security indices based on the assumption of the adversary's full or partial knowledge of previous measurement vectors. We demonstrate success by presenting the Mean Square Error (MSE) for the attacks described and also evaluate the attack model for both the standard IEEE-14 and 30-bus test cases.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126088095","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 method uses Multi-resolution morphological gradient (MMG) algorithm to operate on three phase voltages and currents at target DG location. The result of MMG algorithm is used to compute norm of the three phase voltage and current. The ratio of these norms (voltage and current) are used to obtain a norm ratio index for each phase. Norm index for Islanding detection is obtained by summing the norm ratio index of each of the three phases. Norm index is found to be very effective in detecting island in distribution system with distributed generation integration.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126469881","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 the feasibility of integrating a battery energy storage system (BESS) into a renewable energy park was investigated. The energy park consists of three wind turbines with a total generating capacity of 6MW and 2MW of solar photovoltaic panels. A maximum power export limit of 5 MW to the grid is enforced. The optimal size of the BESS was calculated to maximize the profit made by the energy park through participating in the electricity spot market. To do this, a linear optimization model embedded within a net present cash flow approach was developed. Optimal size of the battery storage capacity and optimal power rating of the inverter for different battery costs assumptions were examined.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127486471","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 topic is relevant in the context of increasing level of power electronic based connections, e.g. wind and solar power plants, HVDC, etc., and due to the increasing development and use of PMU measurement based applications. For this study, several test cases were developed and assessments based on criteria defined in IEEE C37.118.1-2011 standard were made. In the study, three PMU units from different manufacturers were tested and respective results are presented in the paper. It is shown that in general the influence of higher harmonics to PMU measurement accuracy is modest or nonexistent but care should be taken as the exact characteristics of different PMUs is not always available or known.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133682138","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}

Because they require power levels greater than the usual equipment and remain connected for long periods during recharges, EVs can affect the quality of the power supply. In addition, some vehicle brands have the Vehicle-to-Grid (V2G) functionality, which is the possibility of returning the energy stored in the battery to the electric grid. Characterizing these behaviors will allow the Electric Power Distributors to understand the operation of these technologies connected to their networks and to plan the necessary adaptations so that it supports a massive penetration. In this way, this work aims to identify the impacts of these EVs on the power quality. The study was carried out from an extensive set of measurements realized in commercial EVs and in real use.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130819855","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}

Although load forecasting has been extensively studied over the past several decades, the scientific community has not yet paid much attention to industrial load forecasting. The electricity demand of factories depends on many factors, of which some are uncommon or not as important in the classical load forecasting models. For instance, the scheduled processes and work shifts are very important to forecasting short-term industrial loads. In this paper, we offer some insights into modeling industrial loads. We develop a set of multiple linear regression models for an Italian factory that manufactures transformers. The proposed models outperform two other benchmark models for forecasting industrial loads 24 hours in advance.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133103421","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 proposed approach is designed as a multi-step process, where coherent areas are identified and the estimation of aggregated states are obtained using phasor measurement units (PMUs) and non-linear Kalman filter. The wide-area controller is then designed to improve both first swing and post-fault damping stability of the system using available controllable assets in the network, such as FACTS devices. The simulations are performed on the simplified and full model of the Australian national grid, and the controllers have been designed and applied on the available Static Var Compensators (SVCs) in the network. The results show that wide-area controlled SVCs can improve the first swing stability and damp the post-fault oscillations of the Australian network which results in improving the utilization of available transmission network and the overall system security.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133210944","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 power fluctuation process caused by a disturbance is divided into three stages, namely before, during and after the disturbance, and the dynamic equation for each stage is established and the variation of the state point is derived in this study. Based on the theory of the distribution of impact power in the power systems, the change of the tie-line power of a two-area interconnected power system after a disturbance is analyzed. After a disturbance, the tie-line power takes on damped oscillation of inter-area oscillation mode, and the steady-state power value is determined by the total inertia time constant of the generators in both areas. Meanwhile, the expression of power fluctuation, which is similar to the step response of a second-order system and the formula for the peak power during the first power swing are derived. The peak power is mainly determined by the ratio of total inertia time constants of the two-area power system's units and the damping ratio of the inter-area fluctuation mode. The result effectiveness of the proposed equations is verified by the simple system simulation method and the analysis on the generator-tripping contingency of the North China Power Grid and Central China Power Grid interconnected system. The study's conclusions are helpful for operators and engineers to master dynamic characteristics of power fluctuation on AC tie-lines of two-area interconnected power systems. The study provides the scientific basis for arranging operating schemes and control measures of interconnected power systems.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132059112","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}

Particularly when the recent emergence of distributed energy resources is considered. Planners need to ensure that the addition of these resources to distribution systems will not result in violations of feeder limits, and be aware of the point at which system upgrades or management schemes need to be considered. The work in this paper employs a three-phase optimal power flow formulation to determine generic feeder hosting capacities for load and generation. Various hosting capacities are assessed, with the purpose of providing distribution system planners with critical information regarding the limits of their feeders. The formulation detects locations that may be troublesome, and defines the limiting factors of the feeder.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"73 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113983830","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}
