Using Cossembler for Rapid Prototyping of Co-simulations for Power System Operations

Improved modeling and simulation of power and energy systems has become increasingly important in the face of energy transition. The main challenge is to capture the complexity that heterogeneity of technologies and uncertainty of renewable resources bring along. One approach to improve simulation modeling capabilities, that relies on reusing existing expertise and legacy tools, is a so-called combined simulation (co-simulation). In this approach, well-established tools are combined together resulting in simulation environments with greater capabilities. In this paper, we introduce a new co-simulation rapid prototyping tool called Cossembler (which stands for Co-simulation assembler), whose main benefits are high usability and a variety of potential application domains that could be addressed by it. The paper further presents two use cases which illustrate Cossembler capabilities.
