Rule-Based Dispatching of Microgrids with Coupled Electricity and Heat Power Systems

With the extending complexity of microgrid topologies due to the combination of multiple energy resources like electricity, water, steam, and hydrogen, the algorithmic challenges for power dispatch control software increase steadily. Approaches based on mixed-integer programming have strong abilities in modeling complicated dependencies, but come with high requirements on executing control hardware and need special solvers which imply high licensing costs. In this paper, we present a rule-based algorithm for controlling hybrid microgrids that is based on prioritization of buses and components. It can run on small devices and due to its priority-based nature, results can easily be understood and verified by users.
