Thesis Work - Future Value of Residential Flexibility: Aggregation and Service Stacking Across Energy Markets

At Digital Energy Solutions, we develop Vattenfall's digital solutions that make tomorrow’s energy system more efficient, flexible, and secure. Our work spans technologies such as batteries, e-mobility, solar PV, demand response, automation, and secure IT/OT integration, helping accelerate the transition to fossil freedom.

Residential energy assets such as batteries, electric vehicles, solar PV, and heat pumps can provide flexibility to both customers and the electricity system through participation in spot, intraday, and ancillary-service markets. However, the value of these markets changes over time due to variations in prices, competition, system needs, and market design. As a result, market participation strategies need to be flexible and adaptive rather than dependent on a single service or market.

This thesis will investigate how aggregated residential energy assets can be dynamically coordinated across multiple energy markets to maximize long-term value. The work may include:

Historical market analysis
Development of representative asset and household profiles
Future market scenarios
Optimization and/or simulation modelling
Evaluation of different service-stacking strategies
The analysis will consider factors such as asset constraints, customer needs, market commitments, forecast uncertainty, and operational costs.
