Power management of PEV using linear programming with solar panels and wind turbines in smart grids

A high generation of solar panels and wind turbines is able to increase voltage magnitudes of electricity grids, whereas uncoordinated procedures of recharging several plug-in electric vehicles (PEV) have capability to decrease them. Accordingly, this paper proposes a novel decentralized algorithm of power management to reschedule charging and discharging events of PEV over appropriate time slots of energy generation and consumption to maintain voltage profiles within their limits. A linear programming model of optimization is utilized to coordinate bi-directional power flows of charging and discharging PEV batteries, while considering solar panels and wind turbines in smart grids. Simulation results of 7 scenarios show that the proposed strategy is able to maintain voltage profiles of power grids within their margins by charging and discharging PEV batteries over specific hours of energy generation and consumption. The proposed algorithm of power management prevents PEV batteries from being overcharged or deeply discharged by keeping their state of charge between upper and lower boundaries. Therefore, the proposed technique has capability to increase PEV hosting capacity of distribution networks without significant upgrading requirements.
