Abstract <div>The process of designing and evaluating distributed</div> <div>Cyber-Physical Systems (CPSs) is not a trivial task. There</div> <div>are many challenges to tackle such as managing distributed</div> <div>resources, enabling communication between components, and</div> <div>choosing performance metrics to evaluate the “goodness” of</div> <div>the system. Smart Grids (SGs) are prominent representatives</div> <div>of CPSs, a particular type of Critical Infrastructure (CI), whose</div> <div>organizational model is becoming more distributed and dynamic.</div> <div>Due to this paradigm shift, new control and management mechanisms</div> <div>need to be identified and tested to guarantee uninterrupted</div> <div>operation. However, novel approaches cannot always be tested</div> <div>against real networks as the economic cost and risk can be</div> <div>high. In contrast, modeling and simulation techniques are viable</div> <div>evaluation mechanisms that support the continuous evolution of</div> <div>CIs. In this paper, we present an Open Source time-discrete</div> <div>simulation software, called HOLEG, that models and evaluates</div> <div>SGs. The software is based on the Holon analogy, a bioinspired</div> <div>approach that enables systems resilience through flexible</div> <div>reconfiguration mechanisms. The presented software provides</div> <div>features that enable the integration and execution of optimization</div> <div>algorithms along with their evaluation. To demonstrate HOLEG,</div> <div>a case study is presented where a heuristic algorithm is implemented</div> <div>to minimize wasted energy while preventing network</div> <div>destabilization.</div>
