This paper proposes a smart charging coordination strategy for electric vehicles (EVs) in a low-voltage (LV) distribution network. The strategy employs an energy management approach that considers the price sensitivity of EV drivers. Three priority groups are specified based on the EV’s state of charge (SoC) level: high-priority, low-priority, and normal-priority. Different time slots for charging are offered to drivers at varying prices, designated as red, blue, and green time zones. The proposed approach begins with a power flow program that checks all constraints before an EV can be permanently placed on a charging node. An objective function is formulated to minimize production costs while ensuring that the constraints on bus voltages and maximum allowed power consumption are met. Simulation results demonstrate the validity of the proposed algorithm in shifting loads while satisfying all network and EV constraints.

The unit quaternion is popular in the representation and control of rigid body attitude systems. However, it is known that two equilibrium points in the unit quaternion attitude formulation represent a single equilibrium point in a rotation matrix in SO(3). This often leads to a non-efficient control effort as the quaternion transients can settle to either of the equilibrium point regardless of the path taken or, even undergo a homoclinic orbit between the two equilibrium points. This behaviour is referred to as the unwinding effect. This paper presents solutions to cure the unwinding effect in unit quaternion parameterized attitude control systems through the use of a switching parameter or a saturation function.
