The presented work focuses on the introduction of thermal cover factors and the assessment of their interaction with the electrical cover factors. Cover factors are used to quantify the mismatch or non-simultaneity of local production and consumption of electricity and heat. First, the electrical cover factors are redefined to include the losses related to the storage of electricity and other inherent losses. Thereafter, similar thermal cover factors are defined. This allows the assessment of the self-consumption and self-generation for locally generated heat by means of e.g. heat pumps. In this paper, a case study focuses on a net-zero energy building. Net- zero energy buildings require an increase in distributed energy resources (e.g. photovoltaic systems). To minimize the impact of the resulting bidirectional power flows on the distribution grid, demand side management and storage (thermal and electrical) are often mentioned as solutions; i.e. increasing the self-consumption of locally produced electricity. The building in this case study is heated by means of a heat pump. The case study is used to demonstrate the use of the thermal cover factors, as well as the interaction between electrical and thermal energy flows. ispartof: pages:997-1007 ispartof: pages:997-1007 ispartof: CLIMA 2013 location:Prague, Czech Republic date:16 Jun - 19 Jun 2013 status: published |
