Press release:

The combustion of fossil fuels prevailing in the energy sector has adversely contributed to the climate change. Due to that, the future energy generation mix is expected to comprise a high percentage of renewable energy sources (RESs), such as wind and solar power. Given the fluctuating and uncertain nature of such RESs, the future electricity grid will require more flexibility. As a result, policy makers are seeking smart and cost-effective solutions for successful RESs integration. This dissertation probes the potential benefits offered by demand response (DR), sector coupling and their tandem for efficient RESs integration and carbon emission mitigation in various sub-sectors of the energy system.

To accomplish this objective, this dissertation focuses on control strategies and optimization frameworks targeting micro-networks to full national scale system, to regulate the load according to the intermittent energy production thereby optimizing energy payments, carbon emissions and share of RESs. The significance of current electricity and district heat tariffs is also analyzed. The proposed models combined with system planning solutions provide an insight into the load increment and decrement capabilities offered by the collaboration of DR and sector coupling with respect to the power balance and associated costs.

The results of the dissertation are a necessary guide for policy makers, system operators and energy prosumers to compare the economics, feasibility, and effectiveness of available carbon emission reduction strategies.
