System modelling for assessing the potential of decentralised biomass-CHP plants to stabilise the Swiss electricity network with increased fluctuating renewable generation
The CHP Swarm project focused on assessing the potential of decentralised biomass-based combined heat and power (CHP) plants as: a) an electricity grid stabilisation measure to manage an increasing share of intermittent renewable electricity production and b) as a "power on demand" option able to cover shortages of renewable generation over long periods while simultaneously covering heat demand.
It is envisaged that decentralised biogenic combined heat and power (CHP) plants could play a significant role in responding to the challenges facing the Swiss power system by providing more flexibility to balance production and consumption. The potential of this concept was assessed by the development of a CHP swarm model based on detailed technical plant specifications and GIS information regarding the resources and infrastructure, complemented by electricity grid simulation and long-term scenario analysis of the entire Swiss electricity and heat system.
We evaluated the prospects of biomass in stationary applications and grid balancing from an energy system perspective. Bioenergy includes energy from woody biomass (such as forest wood, industrial wood residues, wood from landscape maintenance and waste wood) and wet biomass (food waste, green waste, industrial bio-waste, sewage sludge, animal manure). We enhanced the electricity and heat sectors of the Swiss TIMES Energy Systems Model (STEM), as well as the biomass production and end use pathways. The scenario analysis shows that domestic biomass can contribute 5 – 7% in electricity and 14 – 21% in heat production by 2050.
