Wind Energy in Multi Energy Systems

Dear Colleagues,

Renewable energy technologies, especially variable renewable energy technologies such as wind turbines and solar PV, are in quick development and will become the dominant power generation sources to replace fossil-fuel-based power generation technology in future clean and sustainable energy systems.

However, the fluctuating and fewer controllability features of variable renewable energy, especially wind power, presents significant challenges to the secured and stable operation of power systems, and affects the economics of the renewable energy power generators since the renewable power may not be fully utilized.

Multi energy systems, which integrate electricity, thermal and hydrogen/gas systems together, can explore the interactions of the different energy sectors to support the subsystems each other. For example, providing the power systems with the flexibility by regulating the heat pumps and electrical boilers in thermal systems, by controlling the fuel cells and electrolyser related to hydrogen systems. Further, the renewable power curtailments may be avoided in similar approaches.

Therefore, it is expected the integrated multi energy systems will be an effective approach of fully utilising renewable energy and supplying the energy demands in all energy sectors, including transportation systems.

The objective of this topic is to provide a forum with a set of publication collections to present the current research activities and trends in the area of wind power in multi energy systems. The scope of the topic may include but not limited to the following contents:

• Flexibility of power systems based on large scale wind power;
• Energy markets and wind power;
• Planning of multi energy systems with wind energy;
• Optimal operation of multi energy systems with wind energy;
• Wind Power to X;
• Wind power and transportation systems.
