Many countries are experiencing rapidly increasing distributed generation (DG) of renewable energy sources (RES). Electricity self-consumption is currently replacing feed-in-tariffs (FIT) as one main driver of this development. A prosumer, who is a consumer and producer of energy through his own DG,...

Heat pump and thermal storage sizing studies require modelling to ensure capital and operational costs are minimised. Modelling should consider added flexibility, e.g. grid services, sector coupling benefits, e.g. utilising excess wind production, and access to electricity markets, e.g. time-of-use tariffs....
