Abstract :
Featured by its flexible and reliable operation microgrid has a great prospect for utilizing renewable resources. Electric vehicles can also help relieve the burden of energy supply and environment. Battery switch station (BSS) is an important solution to supply energy for electric vehicles. In this paper a new business model of microgrid-based BSS is proposed. According to battery and charger constraints, a new optimal dispatching strategy of microgrid containing BSS or energy storage station (ESS), wind generator, photovoltaic system, fuel cell, micro turbine and diesel generator is given. The optimization is solved by mixed integer linear programming (MILP). Test cases are carried out to illustrate that additional benefits can be realized by utilizing the BSS as the storage device of the microgrid instead of traditional ESS.
