Application of synchrophasor measurements for improving situational awareness of the power system

The paper focuses on the application of synchrophasor measurements that present unprecedented benefits compared to SCADA systems in order to facilitate the successful transformation of the Nordic-Baltic-and-European electric power system to operate with large amounts of renewable energy sources and improve situational awareness of the power system. The article describes new functionalities of visualisation tools to estimate a grid inertia level in real time with monitoring results between Nordic and Baltic power systems

Categorisation of Ancillary Services for Providers

The focus of the work presented here is to raise awareness of how ancillary services within the NordPool area could be of value in supporting the future grid, and who could be the provider of these services. The ancillary services considered here are not limited to the current market, but also services for future market solutions as well as services for fulfilment of grid codes. The goal is to promote the development of existing and novel solutions to increase the utilisation and thus the value of equipment within the power system. The paper includes a techno-economical categorisation of ancillary services, from a provider\u27s perspective, presenting opportunities and competition. Furthermore, procurers of services could utilise this kind of categorisation to identify possible providers or partners. The analysis of the categorisation shows a broad range of possible providers for each service and a broad range of possible services from each provider

Final Project Report of Cloudgrid

The CloudGrid project is done in cooperation between NTNU, IPE, ZHAW, Chalmers and STRI/ABB. The work is split in six work packages where ABB/STRI, ZHAW, Chalmers and NTNU were package leaders. Besides the authors of this report, the following persons contributed to the project: I. Zikmanis (IPE), M. Calder (ABB), M. Javdani (ABB), A. Babak (Chalmers), A. Bahmani (Chalmers), P. Chen (Chalmers), C. Agathokleopus (Chalmers), O. Lennerhag (STRI/ABB), G. Pinares (STRI/ABB), A. Perez (STRI/ABB) and S. Sanchez (NTNU). The cooperation between the parties is established on many levels. Laboratory facilities and field measurements were shared to a certain extent and data sharing through a cloud was accomplished. This has a high significance for future smart grids where data exchange is essential for stable operation as well as short term and long-term planning. The scope of work covers of the work packages covers a broad range of topics, including stability of current and future power grids, ancillary services, energy management as well as multiterminal HVDC links and high power converter design and control

Electric Consumption Assessment using Smart Meter Data and KPI Methodology

In the modern world, many cities make use of state-of-the-art technologies for a diversity of applications. A field with very specific needs is the electric power system that deals with both large entities that govern themselves (grid operators) and the citizens. For both and all actors in between, there is an increased need for information. Steps to provide these data are always taken and several initiatives are ongoing across the world to equip residential users with last generation smart meters. However, a full deployment is still not possible. Considering this aspect, the authors propose KPIs for the specific situation when some information is available from the meters and other sources, but some is not. The study case is based on a residential area occupied mainly by university students and after an extensive measurement campaign the results have been studied and analysis methods proposed
