Optimal Use of Energy Storage Potentials in a Renewable Energy System with District Heating

Growing shares of intermittent renewable energy sources in power systems lead to temporal imbalances between electricity supply and demand. Technologies which help to balance the electric grid such as energy storages, demand response or flexible coge-neration concepts are therefore gaining on importance. However, the investigation of these potentials from a system perspective requires a simulation approach that takes into account the interactions between supply and demand side as well as power system stability. While most prior studies utilize either linear optimization models to investigate storage options on a system level, or nonlinear simulation models for power system analysis, the present work utilizes a combination of both approaches.
