The concept of Integrated Energy Systems (IES) allows the transformation to a resilient energy system with a high share of renewable energies by coupling the energy sectors electricity, gas and heat. Therefore, the flexibility is increased. The energy system should be resilient against fluctuation in generation, consumption and faults. The security of energy supplies must be evaluated with appropriate methods for developing resilient energy systems. Energy system analysis is conducted using both optimization models and dynamic simulation. Especially the dynamic simulation is suitable for stability studies of IES. Not only the stability but also the compliance to nominal values should be investigated with the developed concept of the Resilience Index. In contrast to this, optimization models can only consider the compliance of energy balances. The dynamic simulation of all sectors is performed as one simulation model for the IES of Northern Germany with the mathematical description language Modelica.
