CheckWatt implements direct frequency control to integrate wind power in energy storage systems

Peter Rosengren 10th May 2022

Technology development provides new opportunities to drive the innovation and the the design of wind farms. CNets spin-off company CheckWatt implements direct frequency regulation for wind power and to enable the integration with battery storage and the option capacity to produce hydrogen.

The SVEF (Sveriges Vindkraftkooperativ Ekonomisk Förening – Swedish Windpower Cooperative Economic Association) has designed an installation to be build north of Ulricehamn.

In the first step three wind turbines from Enercon will be connected to the grid frequency through the new support service FCR-D down, which Svenska Kraftnät introduced on 1st January 2022. This service enables the plants to reduce production within a few seconds if the frequency exceeds the Nordic synchronous range of 50.1 Hz. For owners of wind power this option can generate significant revenue as well as it enables the electrical system to directly utilize a more versatile production environment which enables a more stable operation in general.

CheckWatt enables a 100% renewable energy system through measurement, analysis, visualization and control. CheckWatt’s services offer the following components:

  • Currently – a virtual power plant built from aggregated resources with CheckWatts EMS that supports the frequency of the electricity network and relieves bottlenecks in local networks.
  • IMD – an individual measurement and charging for electricity, water and electric car charging with unique integration to solar power plants and energy storage.
  • EnergyInBalance – a Platform with operational monitoring and visualization for resources with CheckWatt EMS and IMD systems. Also integrated in products of cooperation partners.

Bridge professor’s favorite constructions

Peter Rosengren 21st March 2022

Samhällsbyggarna, an association focusing on the development, building and management of Swedens future society, ran a feature about Raid Karoumi, the Research Director of CNets subsidiary IoTBridge and professor at KTHs department of bridge and steel construction written by Fredrik Hielscher.

An excursion into the fascinating world of bridge constructions and the opportunities new technologies create. Sweden has about 35.000 bridges, a population of constructions that is getting older, some structures over 100 years old, mostly railway bridges. The Swedish Transport Administration’s annual cost for the operation and maintenance of the bridges is around SEK 1.3 billion – a cost that risks increasing rapidly. But new advanced measurement and analysis methods can increase the life of bridges and result in fewer inspections and bridge reinforcements.Sensor-based condition assessment exists already and is used in many of todays products. In modern cars, you get a notifications about changes in the tire pressure, when it’s time to change oil or service the car, issues with system components. It’s the similar with bridges, the technology exists and is ready to be applied to bigger constructions to optimize maintenance and use.

Support of BRIS

Peter Rosengren 18th March 2022

CNet proudly supports BRIS, short for “Barnens rätt i samhället” – childrens rights in society. BRIS is an organization to advocate the rights and living conditions of children and young people in accordance with the UN Convention.

BRIS has daily contact with children and young people via chat, email and telephone. Chat and email can be reached via Bris.se, there is also a forum where children and young people can write and support each other.

The telephone number for BRIS in Sweden is 116111. It costs nothing to call, calls are not visible on the telephone bill and all who contact the organization are completely anonymous.

All requests receive an answer from a trained and experienced curator.

BRIS is member of CHI, (Children Helpline international) which, together with 183 other guides in 142 countries, receives over 14 million calls each year. In addition, the organization is part of Insafe, a European network that works for a safer everyday life for children and young people online.

iBridge presented at Stålbyggnadsdagen 2021

Peter Rosengren 22nd November 2021

John Leander, from CNets subsidiary IoTBridge, presented the project iBridge on this year’s highlight for the steel construction industry, Stålbyggnadsdagen 2021, which was held 28th October in Stockholm.

iBridge aims to develop and demonstrate a full-scale digital instrumentation of bridges. The purpose is to complement manual inspections and to accelerate the industrialization of digital measurement and inspection services. The overall goal is to automate and make available existing knowledge that can reduce the costs for bridge management while guaranteeing safety.

Sweden municipalities alone manage more than 29,000 bridges, in addition to privately owned bridges and bridges owned by Swedish business and industry.

New method to predict life expectancy of machines

Peter Rosengren 1st July 2021

CNets has sponsored a master thesis analyzing a new method to create a health indicator for machines. The master thesis was handed in and evaluated by KTHs School of Electrical Engineering and Computer Sciences (EECS).

The work is based on distance measurements transformed into a vector space through a feed-forward neural network. The neural network is trained using a multi-objective optimization algorithm to optimize criteria that are desired in a health indicator. The constructed health indicator is used as input to a gated recurrent unit (a neural network that handles sequential data) to predict the remaining life of a system in question.

The Master thesis Machinery Health Indicator Construction using Multi-objective Genetic Algorithm Optimization of a Feed-forward Neural Network based on Distance was carried out by Jacob Nyman in the field of machine learning:
