CheckWatt helped stabilise the power grid

When the Finnish nuclear power plant Olkiluoto 3 had to make a sudden shutdown on 19 November, CheckWatt‘s virtual power plant Currently was one of the balance resources activated, instantly providing the grid with 22 MW as frequency support.

Currently is a virtual power plant that aggregates and coordinates thousands of distributed batteries to act as one flexibility resource. Currently supports grid balance services like FCR-D up/down and FFR but also energy arbitrage and increased self-consumption.

Publication out on Vänersborg bridge

The monitoring work performed by IoTBridge in relation to the railway bascule bridge in Vänersborg, Sweden has now been published in a scientific paper. The paper describes the safety assessment processes and the underlying ideas behind them, the challenges encountered, and the developed monitoring dashboard for visualisation of results.

It also explains how the system assesses the structural health of the bridge and how machine learning algorithms were used to automatically detect damages.

Access the dataset from Vänersborg bridge

IoTBridge is now sharing a dataset related to the damage to the bridge in Vänersborg that was recently detected by the structural health monitoring system. The bridge is a single-leaf bascule bridge carrying railway traffic over a canal. It has been monitored by the system since 2021, continuously collecting data from strain sensors, accelerometers, an inclinometer and a weather station. The cloud-based service developed by IoTBridge was used to survey the bridge, and our routines for damage detection discovered a damage event in March 2023 that led to the bridge’s closure.

The dataset contains sensor data from the steel bridge and is unique in terms of the development and testing of routines for damage detection. It contains readings before, during and after the verified damage.

Long-life power platforms for IoT applications

CNet is participating in the LoLiPoP-IoT project which is aiming to improve the battery lifetime and energy harvesting of wireless sensors that are retrofitted in IoT applications for monitoring purposes.

Consisting of 40 European partners, the project is creating an ecosystem of developers, integrators and users to develop power platforms which consider power/battery life, ease of installation and maintenance. Focus is on three main application areas: Industry, smart mobility and energy efficient buildings with use cases for asset monitoring & tracking, condition monitoring for predictive maintenance as well as environmental monitoring. The development of platforms enables reuse across multiple applications and projects.

CNet leads the specification and requirement work for the 10+ use cases, contributing to the development of use cases for district heating and smart buildings.

Apart from reducing the power consumption of sensors, the project will also demonstrate cost reductions, optimised asset management and improved comfort levels for building occupants.

Stöd energiforskare att samla in data

Vårt dotterbolag Checkwatt deltar i ett Europeiskt forskningsprojekt, EVIDENT, tillsammans med Trinity College i Dublin. Projektet arbetar med att förstå hur individer resonerar och fattar beslut i energirelaterade frågor. Denna studie syftar till att förstå hur faktorer som finansiell kunskap och kunnighet i miljöfrågor kan påverka energibeslut. Genom detta hoppas EVIDENT-projektet förstå hur man kan stödja individer att fatta bättre energibeslut och bidra till åtgärder som främjar energieffektivitet.

Om du vill hjälpa forskarna skulle vi uppskatta om du fyllde denna enkät. Det tar cirka 10 minuter. Projektet kommer lotta ut 6 stycken 350 EUR presentkort på Amazon, till de som deltar i undersökningen.

CheckHealth rolls out hypertension platform

Last week the first swedish patients started using the HSmartBPM platform for management of hypertension. HSmartBPM improves effectiveness of the treatment of hypertensive, or undiagnosed high-risk patients by collecting much more data from different sources and by maximizing the benefits of collected data by sharing of data between related actors such as healthcare experts, patients, nurses and informal caregiver under control of patients, in compliance with GDPR requirements. The platform consists of a connected weightscale, a wearable smart watch with built in blood pressure monitor and patient apps for Android and iOS together with a backend and web apps for clinicians. The Swedish patients are all located in Region Jämtland-Härjedalen, Zätagränd Hälsocentral. CheckHealth has the technical responsibility for the rollout of the platform in Sweden.

IoTBridge develops digital twin for bridge

IoTBridge has developed a digital twin that is connected to a bridge monitoring system. The digital twin replicates the health status of the physical bridge and renders the continous sensor measurements from a real bridge, which is located at Bryngeån in the north of Sweden. Check out their demo video. The Building Information Model of the bridge is available in the digital twin making it possible to study individual construction details and how they are affected by train passages.

CheckWatt expands with wind power

CheckWatt has acquired SM Teknik, a technology company specialising in connecting and controlling wind power stations. After this deal CheckWatt is now monitoring 662 wind power stations with an aggregated installed power of 956 MWatt. These power stations will now be possible to connect to the rapidly growing grid flexibility market in Sweden through CheckWatts virtual power plant Currently.

This makes CheckWatt the largest technology- and supplier-independent player in operation monitoring and aggregation of flexible energy resources on the Swedish electricity market.

AI platform for CHF patients

CheckHealth together with a European consortium has won a procurement for innovative services in the healthcare sector. The CORRAL consortium will develop and deliver an integrated care platform which allows monitoring of environmental, physical and psychological patient-related variables, and continuous analysis of recorded data and care team inputs. The platform is based on an artificial intelligence system providing decision support to the multidisciplinary care tea and the provision of personalized support and education interventions allowing patients with cronic heart failure (CHF) to self-manage their diseases.

The system will be installed in five European countries – Sweden, Greece, Turkiet, Italy and Portugal.
