Hybrid Petri nets for modeling and control of multi-source energy conversion systems

This paper proposes an approach of hybrid Petri nets modeling for hybrid renewable energy production systems structured in micro-grids. This approach is original in the sense that it enables to study the behavior of such systems under various reconfiguration constraints in order to fulfill energy demands for customers. The proposed Petri net model allows to considering the discreet events related to the availability of energy resources or to components´ failures in the system as well in the discreet reconfiguration (structural or functional), for control strategies specifications. In addition, an operational research model for cost minimization and availability maximization through reconfiguration is also proposed. The joint implementation of both models should lead to a new approach of design of hybrid renewable energy systems and of their effective cost optimization.
