Storage influence in a combined biomass and power-to-heat district heating production plant

摘要: Abstract The increasing penetration of wind and solar electricity becomes challenging for grid operators. Interconnecting electrical thermal networks through the Power-to-Heat concept brings flexibility to while supplying a significant renewable source District Heating (DH). In present paper, we study DH production plant composed biomass generator, heat-pump heat storage in French energetic context. We assess techno-economic performances this system using Mixed Integer Linear Programming (MILP). A multi-objective parametric optimization method is applied size available quantity biomass, maximum CO2 content minimum energy ratio (REnR) as e-constraints. Our analysis shows that without strong constraints, pump daily are used. For limited amount available, also show investing an inter-seasonal necessary reach high REnR. comparisons, assessed with Danish German electric mix. then verify sizing stage results on operational non-linear numerical simulator. With methodology, it possible evaluate impact MILP modelling level detail obtained results. An error 5.1% trajectories here given system.
