A Linear Model for Operating Microgrids with Renewable Resources, Battery Degradation Costs and Electric Vehicles

Abstract

Due to the growth in the use of renewable energies, the implantation of Energy Storage Systems (ESSs) and the use of Electric Vehicles (EVs), there is a need for optimization models to address these issues in distribution systems. An example of this is the operation of a Microgrid (MG) where the operation cost is optimized. Renewable resources such as wind and solar energy and Distributed Generation (DG) are very important in an MG. In addition, the rise of EVs in distribution systems makes their operation more difficult. This work proposes a linear model to optimize the operation of an MG using a linear AC power flow, renewable resources, DG, Battery Bank (BB) degradation costs and EVs applied to the IEEE 37-bus system. For the creation of EVs scenarios, a software application has been developed using Visual Basic®, MS Excel® and @RISK® to generate them using Monte Carlo simulation.
