- BabelFish (BF) is a real-time data mediator for development and fast prototyping of synchrophasor applications. BF is compliant with the synchrophasor data transmission IEEE Std C37.118.2-2011. BF establishes a TCP/IP connection with any Phasor Measurement Unit (PMU) or Phasor Data Concentrator (PDC) stream and parses the IEEE Std C37.118.2-2011 frames in real-time to provide access to raw numerical data in the LabVIEW environment. Furthermore, BF allows the user to select ‘‘data-of-interest’’and transmit it to either a local or remote application using the User Datagram Protocol (UDP) in order to support both unicast and multicast communication. In the power systems Wide Area Monitoring Protection and Control (WAMPAC) domain, BF provides the first Free/Libre and Open Source Software (FLOSS) for the purpose of giving the users tools for fast prototyping of new applications processing PMU measurements in their chosen environment, thus liberating them of time consuming synchrophasor data handling and allowing them to develop applications in a modular fashion, without a need of a large and monolithic synchrophasor software environment.

- The electric power grids expose highly dynamic behaviors that can be mitigated by exploiting Wide-Area Monitoring, Protection And Control (WAMPAC) technologies. These technologies rely on utilizing the synchrophasor measurements provided by the Phasor Measurement Units (PMUs). The IEEE C37.118.2 standard defines a method for real-time communication of synchrophasor data between PMUs, Phasor Data Concentrators (PDCs) and other applications. This paper describes the Smart Transmission Grid Operation and Control (STRONgrid) library, which serves as a real-time data mediator (i.e. interface) between the IEEE C37.118.2 protocol and applications consuming PMU measurements. The STRONgrid library packages all the necessary components to allow the researchers to focus on the development of synchrophasor applications in higher level programming environments (e.g. LabVIEW).

- Power system studies seldom consider the interaction between transmission and distribution systems. This sort of analysis, however, have been gaining importance due to the progressive growth of renewable energy penetration in the distribution networks. In this context, the current study combines a positive-sequence transmission system model with a three-phase distribution system model. The connection between both systems is attained by a hybrid three-phase to single-phase interface element. The system model is written in Modelica language, and simulated using OpenModelica. A test system is built o top of the IEEE14 test system, where two load buses are expanded into three-phase distribution systems. Results of studied system are validated against the power system simulator, Simulight. Results also renders the presently analyzed hybrid model very promising for complimenting modern power systems studies.

- Traditional simulation tools for power system studies are, in general, shipped with built-in and closed model libraries. Typically, the models' implementation is not thoroughly documented, preventing the user to gain a full understanding of their implemented behavior. Previous efforts from the authors have focused on the development of an open source software library of power system components developed using Modelica: the Open-Instance Power System Library (OpenIPSL), which provides models that can easily be accessed and studied by the user. Recent developments have focused on the implementation of a software architecture facilitating collaborative developments on OpenIPSL. Employing the latest technologies available in the software development community, this paper details the implementation of a continuous integration workflow, providing automated testing and behavior verification of the library's models. This platform seeks to increase the library's stability and to provide more reliable models developed collaboratively by multiple individuals. Moreover, this software architecture only utilizes open source software, which can be hilly tailored to the specific needs of users and other library developers.

Tidskriftsartikel (refereegranskat)abstract
- This article presents an open data repository, the methodology to generate it and the associated data processing software developed to consolidate an hourly snapshot historical data set for the year 2015 to an equivalent Nordic power grid model (aka Nordic 44), the consolidation was achieved by matching the model׳s physical response w.r.t historical power flow records in the bidding regions of the Nordic grid that are available from the Nordic electricity market agent, Nord Pool.The model is made available in the form of CIM v14, Modelica and PSS/E (Siemens PTI) files. The Nordic 44 model in Modelica and PSS/E were first presented in the paper titled “iTesla Power Systems Library (iPSL): A Modelica library for phasor time-domain simulations” (Vanfretti et al., 2016) [1] for a single snapshot. In the digital repository being made available with the submission of this paper (SmarTSLab_Nordic44 Repository at Github, 2016) [2], a total of 8760 snapshots (for the year 2015) that can be used to initialize and execute dynamic simulations using tools compatible with CIM v14, the Modelica language and the proprietary PSS/E tool are provided. The Python scripts to generate the snapshots (processed data) are also available with all the data in the GitHub repository (SmarTSLab_Nordic44 Repository at Github, 2016) [2].This Nordic 44 equivalent model was also used in iTesla project (iTesla) [3] to carry out simulations within a dynamic security assessment toolset (iTesla, 2016) [4], and has been further enhanced during the ITEA3 OpenCPS project (iTEA3) [5]. The raw, processed data and output models utilized within the iTesla platform (iTesla, 2016) [4] are also available in the repository. The CIM and Modelica snapshots of the “Nordic 44” model for the year 2015 are available in a Zenodo repository.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The share of wind power has strongly increased in electricity production, raising several issues concerning its integration to power grids. Unexpected dynamic phenomena, such as oscillatory events around 13 Hz have been recorded in the US by Oklahoma Gas & Electric (OG&E). Such interactions differ from traditional and well studied inter-area oscillations, and the ability to detect them is beyond the measurement capabilities of most of the existing measurement equipment and monitoring tools in Energy Management Systems (EMS) systems. This chapter presents the development and implementation of algorithms for fast oscillation detection, focusing on the aforementioned case. It proposes two solutions for real-time monitoring application that exploits synchronized phasor measurements allowing real-time analysis of sub-synchronous wind farm dynamics. These tools were built as prototypes for real-time application which utilizes Phasor Measurement Unit (PMU) data for enhanced monitoring and control of wind farms. The software tools developed in the chapter serve as evidence of the flexibility offered by non-conventional software development systems for PMU applications which provide unlimited opportunities to conceive new software tools that will aid with the integration and management of renewable resources into power grids.

RaPId: A modular and extensible toolbox for parameter estimation of Modelica and FMI compliant models
- 2016
-
Ingår i: SoftwareX. - : Elsevier. - 2352-7110. ; 5, s. 144-149
-
Tidskriftsartikel (refereegranskat)abstract
- This paper describes the Rapid Parameter Identification toolbox (RaPId), developed within the EU FP7 iTesla project. The toolbox was designed to carry out parameter identification on models developed using the Modelica language, focusing in particular on power system model identification needs. The toolbox has been developed with modularity and extensibility in mind, using Matlab/Simulink as a plug-in environment, where different tasks of the identification process are carried out. The identification process uses different optimization algorithms to improve the fitting of the model’s response to selected criteria. The modular architecture of RaPId gives users complete freedom to extend and adapt the software to their needs, e.g. to implement or link external solvers for simulation or optimization. The compatibility with Modelica models is brought by the use of technologies compliant with the Functional Mock-up Interface (FMI) standard.
