Network balancing from large parking facilities and commercial buildings

Alternative title: Nettbalansering fra store parkeringsanlegg og næringsbygg

Awarded: NOK 7.1 mill.

The share of renewable energy is increasing, both nationally and globally. Power from renewable energy is weather dependent, while the shift from fossil energy to use to electricity increases variation in demand. In the project "Network balancing from large parking facilities and commercial buildings" "(NeX2G) we will investigate if energy storage in EV-batteries together with control of energy consumption in buildings can contribute to a more flexible and thus economical energy use. Flexibility facilitates high electricity demand at night and less in the morning and afternoon. Thus, reducing power peaks and need for grid expansion. We use Oslo Airport Gardermoen as a case. At airports, it is predictable how long the car owners want to leave the car parked and thus how long the electric car batteries are available. We will develop a program to calculate the potential for flexibility. That is, a model for optimal use of the energy storage, and which also ensures the car owner a charged battery when the car is picked up. Furthermore, we will analyze economic benefits both socio-economically and privately financially for the players. Price development for two-way chargers is an important factor. We are in the process of buying five two-way DC chargers that will be installed in the parking garage P10 at Gardermoen. Furthermore, we identify energy-intensive equipment such as ventilation systems and water heaters that have the potential for flexibility, where we have independent data that can be used in machine learning algorithms. Optimization models will be used to predict flexibility based on data collected and experience of seamless energy exchange and flexibility services combined. Several alternative options for relieving the power grid (X2G) and thus reducing the need for grid expansion have been proposed in the literature. We will compare costs for our flexibility with other flexibility that can be offered. We will analyze this for the northern European power system with the energy system model Balmorel.

NeX2G is a Collaborative and Knowledge-building Project that will meet societal and industry-related challenges (KSPK). The project will investigate the potential magnitude and economic sustainability of flexibility available to the energy system from long-term parking of electrical vehicles (EVs) and commercial building assets. We will use Oslo airport Gardermoen as a case and work with real time data as basis for detailed and aggregated analysis. Airports are interesting because future power demand will increase substantially and they will in the future have a large pool of parked EVs. Five bidirectional EV chargers will be installed at the airport together with devices to collect real time data on operation and control of chargers and selected building assets. Machine learning algorithms will be used to predict the flexibility based on the collected data and experience with seamless exchange of energy, grid and flexibility services collected. Use of EVs as energy storage requires robust technical solutions, marketplace development, visualization of benefits and possibly policy incentives. Moreover, the comparison of economic benefits for the owner (Avinor) with the socioeconomic benefits and need for policy is crucial for the realisation of X2G.
