Energy dispatching strategy for micro-grid using hybrid Petri nets model

Autonomous installations supplied by renewable energy sources are usually sized to cover yearly user needs. This involves sometimes an energy deficiency or excess when the need does not meet generation. In case of neighboring autonomous installations, some run into a lack of energy while neighbors provide an energy surplus. Consequently, interconnecting installations via a Micro-Grid should solve the problem. This paper suggests a Hybrid Petri Net (HPN) strategy for micro-grid energy provider in order to make decision on dispatching energy between connected installations. A HPN model combines discrete events (house state) and continuous events (energy flow) to cover the need of some installations by energy surplus offered by neighbours.
