Optimal Energy Management of an Energy Hub, Integrating Renewable Resources and PHEVs

The commitment of countries to implement environmental conventions increased the usage of renewable energy sources such as photovoltaic modules and wind turbines, and also electric vehicles to reduce pollutant emissions in both of energy generation and transportation sections. High uncertainty at the time, location and amount of charging of electric vehicles causes negative impacts on the power system operation. On the other hand, the dependence of the power output of photovoltaic modules and wind turbines to weather conditions caused installing more storage devices in the energy system. Hence, using the battery of plug-in hybrid electric vehicles (PHEVs) as storage system is a suitable solution for the integration of renewable sources in power systems. In this paper, a new model based on energy hub conception is presented for optimal operation of a grid-connected microgrid that contains renewable sources and PHEVs. The proposed model is developed by GAMS software and the results are evaluated
