PROACT: enabling Pro-Active Maintenance in the grid A pro-active system solution using PQ data and AI for trend forecasts that can be used to avoid severe disturbances, and a WEB-based visual interface. The solution can be integrated with existing DSO/TSO systems and used for trend forecasting for different KPIs (energy, power and disturbance classification). Used […]

Multi-tool visualises grid utilisation rate and consumption patterns A web-based prototype multi-tool based on PR technology that visualizes and forecasts electrical grid capacities and identifies potential flexibility. Showing the power grid’s various levels, this tool is valuable for network planning, operation and maintenance. Combining with data from other sources increases the value further and enables […]

Micro-grid concept improves solar PV harvesting A new modular, scalable and flexible micro grid system was developed and demonstrated, where batteries and a smart controller were used to maximise the use of solar energy. Advanced data analysis was used to verify the functionality in addition to identify opportunities for increased harvesting of solar energy. PR […]

Conservation Voltage Reduction (CVR): a study combining measurement and analysis A study on possibilities to curtail the power use in a grid by reducing voltage levels. CVR enables peak shaving, increases capacity and optimized operation. This requires increased measurements and communication costs, resulting in reliability risks and risk of violating power quality. Since the effectiveness […]

Improved Hosting Capacity: enabling higher levels of renewables Creating higher accuracy than regular theoretical calculations used today, EPR improved the tool for grid operators to assess the capacity for hosting renewable energy. Combining power quality measurement with multi-KPI-analysis, a larger amount of renewable generation can be integrated without an increase in costs or risk. Further […]

Inertia support by wind turbines: a study at Bares wind farm Increasing renewable energy penetration has decreased the grid’s inertia due to the power electronic interface with the grid. In this study, ENERJISA’s BARES wind farm has been modelled in a simulation environment. Each wind turbine stores almost 18 MJ kinetic energy in the rated […]
