Abstract

We present a holistic approach of modeling complex energy systems (MOCES). It follows the need for multi-domain
models and appropriate tools for the design and evaluation of new concepts and ideas related to the upcoming Smart Grid. As an adequate approach, MOCES is capable of modeling physical systems as well as the mainly event-driven behavior of interacting entities and feedback loops across the domains. In addition, it covers timescales from seconds to days. Contrary to other approaches following an agent or co-simulation concept, MOCES is monolithic, based on the modeling language Modelica. To meet the requirements imposed on a simulation tool, we use the possibility to enhance Modelica within its language specification. The basic idea of MOCES is to extend the physical model of each entity by a connected representative in a parallel simulation. To show the feasibility of the concept, a simulation example investigates the benefits and drawbacks of local energy markets.
