This paper examines a combination of the adaptive unscented Kalman filter (AUKF) and the fast upper diagonal recursive least square (FUDRLS) for the parameter identification and SOC estimation processes, respectively. The analysis focuses on on-line applications and the results are compared with previous work.

With efficient exploitation of all the available resources in the grid, many related problems can be solved. The problem addressed in this paper is becoming more and more common in the practice. There is a need to control reactive power exchange between the grids of different voltage levels. This need becomes more pronounced with increasing penetration of distributed generation and cables in the system. But, the cause of the problem can be also a part of its solution. This paper shows that it is possible to control the reactive power exchange to a noticeable extent using the distributed generation located in the grid and the on-load tap changers. The results have been obtained from the analysis of a representative model of Swedish distribution network with installed DFIG wind turbines. While not going deeper into the control strategies, the reactive power boundaries of the system are identified. Critical elements are found for different case scenarios. Solutions on adjustment of reactive power capabilities of the grid are proposed.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"20 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":"125265762","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 VSC-MTDC networks are expected to play an eminent role in interconnecting AC grids, there is a growing need to optimize the placement and design of supplementary controllers in the MTDC converters, in order to maximize their benefit to the connected AC systems. Based on small signal stability analysis of the system, the location of damping controller within the MTDC network is selected according to the eigenvalue sensitivity of poorly damped oscillatory modes. On the other hand, the design of the damping controller is based on Modal Linear Quadratic Gaussian (MLQG) control that uses Wide Area Measurement Signals (WAMS). The results show the ability of the controller to enhance the damping in the system in case of disturbances, as well as to improve the small signal stability by boosting the damping of inter-area modes.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"7 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":"121838314","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}

Conventionally, the optimal number of PMUs in a system is determined based on the system's connectivity matrix under no contingency. This paper considers fault-tolerant PMU placement under single branch failure, using integer programming based methodology. Algebraic connectivity, or Fiedler value, is utilized to identify the worst-case single branch failure in terms of connectivity degradation. The proposed PMU placement accounts for this worst-case and covers a large percentage of other single-branch failures. The resulting placement is compared with that obtained without considering connectivity degradation in terms of the percentages of observable systems during any single branch failure. The proposed PMU placement has increased percentages of fully observable systems in the event of any single branch failure compared to non-contingency based placement, with a reasonable increase in number of PMUs.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"44 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":"133690617","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}

Different from the traditional controller design approach, the mode-based approach assumes that an ESD is equipped with a set of predetermined real-time control modes. Thus, the control objective becomes choosing the best operation mode of the ESD to achieve the best performance at the lowest cost instead of the charging and discharging power levels. As a result, a two-stage algorithm is developed. In the first stage, an economic model predictive control (EMPC) algorithm is used to determine the optimal charging or discharging power. In the second stage, based on the EMPC result, the controller eliminates unsuitable modes and selects the best operation modes among the suitable modes. Residential electricity consumption data collected in the PECAN Street Project are used for testing and validation of the proposed algorithms. Simulation results show that the performance of the mode-based controller is robust and consistent across different residential load patterns.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"25 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":"134278298","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}

Thus instabilities due to, e.g., line overload, occur more often, increasing the risk of failures. A single failure can originate cascading events and finally end up in a blackout. Reactive control actions aim to overcome such failures a posteriori, whereas proactive ones prevent failures, contributing towards a self-healing and self-organizing smart grid. Moreover, the involvement of communication networks into grid monitoring, management, and control introduces an interdependency between these two systems, which increases the risk of instabilities due to propagation of failures from one system to another. This paper gives an overview of detection and mitigation methods of cascading failures in power grids and communication networks and presents the challenges and open questions in managing such failures in interconnected networks.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"222 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":"115534218","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 contrast to conventionally used average voltage source converter (VSC) models for frequency support system studies, advanced MMC models provide a different dynamic behaviour due to their decoupled ac and dc current control. Following the underlying converter and dynamic ac grid models, four different methods for primary frequency support by MMCs are presented in this paper. The individual control designs differ in their required input signals, controller characteristics in terms of proportional or PI structures and potential applications with respect to ac system properties. To prove the overall functionality and to highlight differences in the respective dynamic system responses as well as recovered steady-state conditions after occuring active power imbalances, a comparison using numerical simulations is carried out for a point-to-point MMC-HVDC transmission system connecting two non-synchronous areas.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"154 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":"114165431","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}
