In the three-phase four wire system of the low voltage side for the distribution grid, the phenomenon of asymmetrical and uneven single phase load were very common, causing unbalance in certain network. When unbalance exists, the system will have a larger line loss and the unbalanced loads can result in efficiency reduction of power energy and voltage quality decline. And then the safety and stabilization of power system in the low-voltage distribution grid will be directly affected. Therefore, based on the problems above, combined with the characteristic of the low voltage distribution grid in the three-phase four wire system, a three phase load unbalance automatic regulating system for low voltage distribution grid is designed. The system is composed of intelligent phase change controller and phase commutation switch. Based on the relevant theoretical analysis and experimental research applied in the system, the results show that this system can reasonably reduce load imbalance, improve power system performance, economic and social benefits.

Microgrids (MGs), which can operate either interconnected or isolated from the bulk grid as one controlled entity, are low voltage distribution networks comprising various distributed generators (DGs), storage devices and loads. This paper proposes a particle swarm optimization (PSO) method for solving the economic dispatch (ED) problem of a MG power system. Vehicles plugged into the MG can be used as mobile storage devices, which supply power to the MG system when the load is in the peak. The experimental results show that the plug-in electric vehicles (EVs) can improve the economic of the MG system.
