Power Management Simulation of a Renewable Energy Microrid Using Coloured Petri Nets

Abstract

In this study, an analysis of the energy comsumption and storage was carried out in a microgrid composed of renewable resources (photovoltaic and wind energy generation), consumers and energy storage. For this, a simulation was carried out using Colored Petri Nets (CPN). The study is carried out to seek a feasible dispatch and a maximum storage load so that it does not generate power outages for the end consumer. Demand, supply, storage load, energy balance and grid injection or consumption will be the final results of the simulation to be subsequently analyzed to evaluate the performance of the simulation. Three scenarios is analyzed, without storage, with well-sized storage and with a under-sized storage. The scenario without storage helps to size the storage to prevent grid injection and prevent grid energy consuming beyond the renewable resources to make the system to operate isolated.
