Flexibility applied on ancillary services
Introducing variable distributed generation (DG) will increase the need for flexibility in the grid. The development of a flexible energy system is crucial to realise energy and climate targets and to ensure security of supply in Norway and Europe. To obtain this, flexibility on the distribution level such as battery banks, generation units and dispatchable loads are crucial.
CINELDI aims to develop methods and models for cost effective integration of flexible resources in smart distribution grids, and to develop concepts and solutions for utilizing flexible resources in different market products and ancillary services. To achieve this, different technologies and market options needs to be tested and verified in real environments.
NODES flexibility platform
iFleks, a pilot project concerning price sensitivity is conducted by Statnett, with CINELDI participation in the project reference group.
This pilot aims to understand how variable end-user-prices of electricity affect the power consumption in peak periods, as we expect stronger price signals and smart appliances in the future. The project focuses on household and business costumers in city regions and performs real-life price experiments with them. Participants receive price signals, that they can react to voluntarily by reducing their power consumption and get paid accordingly to the price signal.

A smart grid is not only about using newer, smarter technology such as sensors, machine learning and batteries to increase security of supply and grid flexibility. It is also about the end user, i.e. the customer, and how we consume electricity.
Tariffs may incentivise customers to change their consumption in order to reduce peak loads in the grid and thus reduce the need for investments in the future. To find out which tariffs to choose, CINELDI and Elvia are running the pilot project Active homes, investigating how different tariffs and/or communication messages affect end-user-flexibility, helping Elvia decide on which tariffs to choose for the full roll-out.
Different tariffs have been evaluated. Now, the most promising tariffs are being tested in Active homes.

Grid flexibility and distributed energy production changes the premiss for buying and selling power. CINELDI partner NODES is operating a new marked platform, facilitating optimal use of flexibility in the grid. Linja and Haugaland Kraft both have a pilot project investigating the use of the NODES market platform for local flexibility market.
The flexibility market at Linja will be established at Bremangerlandet to solve local grid capacity issues. A new power line is planned to be finalised in 2022, and the flexibility market will be a temporary solution to solve grid problems.
Haugaland Kraft will investigate the use of a local flexibility market on an island, Utsira, where different flexible resources will be available (flexible load, energy storage and distributed generation). Today the island is supported from the mainland via a submarine cable, and an electric ferry is planned to be charged at the island. The flexibility market will be evaluated as a solution to trade available flexibility to keep a stable power system on the island – also during charging of the ferry.

Optimisation of local balancing with battery
Batteries as voltage support
Together with Skagerak Energi, CINELDI is running a pilot at Skagerak Energilab. The lab is a unique large-scale pilot facility for local generation (PVs) and storage of electrical energy.
It is used for testing different operational modes, including local balancing of load and generation using a battery energy storage system.
We are now planning to test the optimization of local balancing by combining methods for optimal control and prediction algorithms for load and photovoltaic generation. The goal is to give insight into how such systems best can be utilized as a flexible resource providing services to the grid and to external actors.

Under-dimensioned power grids can cause power quality issues for customers and trigger large investments for grid companies. Lyse Elnett is investigating, together with CINELDI, if off-the-shelf battery-systems can be a temporal or permanent alternative to grid upgrades.
In the fall of 2019, a 18 kW, 19,6 kWh battery-system was installed to act as voltage support in a 230 V power grid. We have gained valuable experiences in how the battery system operates and its contribution to reduce slow voltage variations.
In the next phase of the pilot we will investigate measures for voltage regulation adapted to changes in ambient temperature, reduction in voltage response times and increased efficiency of the battery-system.
