Description
Summary:The increasing use of fluctuating generation plants like wind turbines and solar power systems, makes new demands on the existing power grid. These are considered to be essential for low-voltage grids. Based on the latest request from the German Federal Government for a progressive improvement of the heat insulation of the residential building stock the impact of a comprehensive passive house standard is analysed. Seeing that, a prediction for the future perspective of natural gas grids and district heating grids throughout Germany in 2050 has been done. Regarding this context the role of decentralised combined heat and power (CHP) as well as heat pumps increases [1]. In connection with enlarged thermal storages, their specific application can add a substantial contribution in combination with an aimed electricity supply of 100% renewable energy. The rational use of these and other supply systems is investigated within a basic virtual power plant model.
