Improving the interaction between Net-ZEB and the grid using advanced control of heat pumps
Authors: Publication Year: 2013

Design principles in Net-ZEB considers the local energy infrastructure as virtual storage leading to large amount of energy exchange with the grid. Nonetheless, with high Net-ZEB penetration scenarios, such exchange could compromise the effectiveness of Net- ZEB concept in a total energy infrastructure. As the current market trends, heat pumps along with photovoltaics are seen as an emerging energy supply solutions in Net-ZEB buildings, effectiveness of an all-electric Net-ZEB (that is using air-to-water heat pump with photovoltaic) is analysed. Two concrete control cases of energy storage (compared to reference case) to assess Net-ZEB ability to self-consume vs. grid empowerment are studied. Results shows that introduc tion of storage buffer in such concept leads to a flexibility of almost 6 % in self-consumption and 13 % in grid-impact factor and in-turn provide significant manoeuvring space to the demand-supply balance at the grid level.
