Despites all of its merits, VSCs have not been favored in very weak grids because of stability issues. Recently, these issues have generated much attention in literature and different solutions are proposed. Among the discussed solutions, the artificial bus is one of the most straight-forward and effective methods, which enable VSC to inject or absorb its maximum nominal power. However, this method is not examined under grid disturbances. This paper studies the impact of severe faults, phase jump and frequency changes and discusses the inherent robustness of the method to fill a serious gap in the literature.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123198559","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 deregulation of the power industry in many countries has magnified the importance of this need. Research in this area has included the use of shallow neural networks and other machine learning algorithms to solve this problem. However, recent results in other areas, such as Computer Vision and Speech Recognition, have shown great promise for Deep Neural Networks (DNN). Unfortunately, far less research exists on the application of DNN to short-term load forecasting. In this paper, we apply DNN as well as other machine learning techniques to short-term load forecasting in a power grid. The data used is taken from periodic smart meter energy usage reports. Our results indicate that DNN performs quite well when compared to traditional approaches. We also show how these results can be used if dynamic pricing is introduced to reduce peak loading.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115989909","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 PNM scheme, OLTC and VR are restricted to only regulate the secondary bus voltages at fixed set-points, while in ANM scheme, control of the secondary bus voltages within the statutory voltage range is allowed, thus providing area-based voltage controls. In this paper, the dynamic model of a 33kV 16-bus United Kingdom generic distribution system (UKGDS) is firstly implemented in PSCAD/EMTDC and validated with a steady-state model, using optimal power flow (OPF)-based technique, developed in GAMS software. Secondly, the OLTC and VR controls under ANM and PNM schemes are developed with discrete tap-changers, and tested considering different load profiles and dynamic loads. The results show that the ANM scheme allows considerable utilization of OLTC and VR compared to PNM scheme, but also may increase the loading of these devices depending on load levels and voltage profile in the power network.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123585977","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}

As the importance of cyber-physical system (CPS) security is growing, various vulnerability analysis methodologies for general systems have been suggested, whereas there has been few practical research targeting the smart grid infrastructure. In this paper, we highlight the significance of security vulnerability analysis in the smart grid environment. Then we introduce various automated vulnerability analysis techniques from executable files. In our approach, we propose a novel binary-based vulnerability discovery method for AMI and EV charging system to automatically extract security-related features from the embedded software.

Therefore, the calculations of real and reactive power for PV inverters are important. In this study, a novel direct power control (DPC) strategy for three-level single-phase grid-connected SVPWM inverters has been developed. In this strategy, the real and reactive power control and SVPWM are considered in inner loop, while a voltage PI controller is used in outer loop to acquire constant output voltage and provide power reference to the DPC. In addition, the MPPT algorithm is integrated into the control strategy to get the maximum PV output. The performance of the proposed method is verified by simulation results obtained using Matlab/Simulink.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122644660","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}

Rather than relying on controllable loads from disparate individual buildings, SunDial uses a Facility Load Aggregation and Management Engine (FLAME) that provides a single point of input for managing the electric loads in multiple commercial and/or industrial facilities. By implementing various demand response strategies, FLAME acts as a virtual energy storage resource, thus increasing the roundtrip efficiency and capacity of the Sundial's coupled battery/load-based storage system. An open standard to support broader utilization of long-duration load shifting as a means to enable grid integration of distributed renewables is also proposed. The SunDial system is planned to be deployed in Massachusetts in 2017–2019 on the National Grid distribution system.

This transition requires increasing the observability and awareness of the interactions between Transmission and Distribution (T&D) grids, particularly to guarantee adequate operational security. As part of the work carried out in the EU-funded IDE4L project, a specific use case, containing PMU-based monitoring functions, has been defined to support the architecture design of a distribution grid automation system. As a result, the architecture can accommodate for synchrophasor applications that provide key dynamic information extraction and exchange between DSO and TSO.

Unlike the traditional power generation methods (i.e. oil and gas), the solar output power is fluctuating and uncertain, mainly due to clouds movement and other weather factors. Therefore, in order to have a stable power grid, the electricity utilities need to forecast the solar output power, so they can prepare ahead adequately. In this work, hour-ahead solar PV power forecasting is performed using Support Vector Regression (SVR), Polynomial Regression and Lasso. The implemented regression models were tested under different feature selection schemes. These features include weather conditions (i.e. sky condition, temperature, etc.), power generated in the last few hours, day and time information. Based on the comparative results obtained, the SVR forecasting model outperforms the other two models in terms of accuracy.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115453759","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}
