Improving the energy efficiency of residential buildings is of paramount importance to reduce CO2 emissions and hence to achieve a climate-neutral building stock - the objective of the German government for 2045. Thereby, a focus on the existing building stock is needed, as regulations for new...

Forecasting hourly electricity prices and their characteristic properties is a core challenge for energy generation companies and trading houses. The short-term marketing and purchase of electricity is usually managed with standardized products traded on different markets and with specific...

The integrated provision of energy among various energy sectors plays an important role in the process of decarbonisation of large energy systems. An important pillar is thereby the decarbonisation of the heat sector, where nowadays still a large percentage of heat supply originates from...

The German government aims at a climate-neutral building stock by 2050 to reach the goals defined in the Climate Action Plan 2050. Increasing the energy efficiency of existing buildings is therefore a high priority. For this purpose, investments of private homeowners will play a major role since...

The ongoing transformation process towards a low or even zero emission energy system is facing a steadily increasing complexity, notably through variable renewable energies and sector coupling. At the same time, the necessity for long-term decisions associated with high capital costs remains....

Growing shares of renewable energy sources (RES) in the electricity system increase the need for flexible balancing of supply-dependent feed-in of RES and time-varying demand. Besides flexible, conventional technologies and demand-responses, storage is an important option. Through the use of an...

With the increasing amount of volatile infeed from renewable energy sources the need for flexibility becomes more and more urgent. This holds especially for the distribution grids where critical load situations caused by high local renewable infeed occur increasingly often. Therefore, demand...

We develop an analytical model to derive the competitive market equilibrium for electricity spot and reserve markets under stochastic demand and uncertain renewable electricity generation. We then derive the welfare-optimal provision of reserves. At rst-best, cost of reserve capacity is balanced...

The share of solar energy in German electricity generation has increased strongly over recent years. This is largely due to guaranteed feed-in tariffs together with decreasing prices for solar panels. Residential PV systems play a decisive part providing households with a possibility to...
