CPD 14 hours

Special sessions

Power to gas: The missing link for the energy transition?

Organizer(s): Dr. Bedel Laurent, French Alternative Energies and Atomic Energy Commission´╝î; Dr. Shi You, Technical University of Denmark,

The massive deployment of intermittent renewable energies will require the development of infrastructure of energy storage. Power to gas solution offers an electric grid service and a massive energy storage. It also addresses several markets, indeed Power to Gas is a link between the different energy networks. The conversion of electricity to hydrogen (PtH2) and to methane (PtCH4) followed by an injection into the gas grid or stored in tanks allows long-term storage.

This special session aims at bringing together industrial experts, business and technical solution developers, hydrogen and methane end-users and researchers to create the focus and critical mass for accelerating the onset of hydrogen economy by using hydrogen solutions for grid services. The carbon dioxide captured from flue gas, biogas or from atmosphere and converted into methane allows the storage and the transportation of hydrogen for current mature markets.

Papers in this special session are as follows:
  • Introduction to power to gas: Concept, processes, technologies and uses
  • Performance evaluation of methanation reactors for CO2 hydrogenation and application to power to gas
  • HYDEPLOY project: First UK project of H2 injection into the gas grid
  • The Jupiter 1000 Project: First industrial demonstrator of power to gas in France
  • The first step of unlocking the value of using Electrolysers for grid services: understand the technical requirements and the Electrolysers’ abilities
  • Underground Sun Conversion: Renewable gas produced from solar power and water – 1,000 metres underground
  • TheHyBalance project: Demonstrating the use of hydrogen in energy systems

Modelling, control and stability of power converters for renewable energy system

With the rapid growth of renewable energy generation, more and more power converters are put into use, which is being likely to play the leading role in future power system.

The power converters are not only used to transfer the renewable energy (PV, Wind and etc.) to the customized power, but also used to stabilize the power system with various faults. Recently, the power flow in the power system is gradually tended to be controlled through the power converters, such as the prosperous using of HVDC and SST(solid state transformer). In this way, the interconnection of different topologies is taking into common consideration.

The issues of modelling, control and stability of the power converters system are no longer limited to the small signal or linearized system.
There are many technical challenges: lack of standardised modelling method for the interconnected system, useful system approximation of large signal, useful equivalent circuit, inadequate stability and versatile control design, harmonics and oscillations in the interconnected system, reduction of electrolytic capacitor in the interconnected system and etc.

Research is being carried out in both the system and equipment levels of design, modelling, analysis, operation, control and stability of grid connected converters for renewable energy, HVDC, SST and etc.

Papers in this special session are as follows:
  • Unified ZVS strategy for DAB with Triple-phase-shift modulation in boost mode
  • A Novel third-order harmonic currents suppression method based on selective component compensation for cascaded H-Bridge STATCOM under asymmetric grid
  • Modelling and stability analysis of photovoltaic-battery hybrid power system with rapidly changing load
  • Fault operation analysis of DC transformer in PV medium voltage DC power collection
  • Research on three-level inverter for permanent magnet synchronous motor system based on deadbeat control
  • Master-Slave Current Regulation of an LCL-Filter-based Grid-Connected Inverter under Variable Grid Condition
