Nowadays, planning for the optimal use of electrical vehicles and their connection to the power grid has become of growing interest. The load resulting from long charging time requirements of such vehicles would lead to increased load of distribution grid and endanger system security and extra voltage across the distribution grids. On the other hand, the penetration of photovoltaic resources and uncertainty in their generation would affect the quality of consumers’ electricity. In order to solve this problem, the present paper applies the smart load structure with a back-to-back converter for voltage adjustment so that the grid would be able to support the exchange of active power with load-serialized converter. The quantities of active and reactive power in this system are determined using the possible load dispersion and Monte Carlo simulation. The simulation results indicate the efficiency of this method in improving the quality of consumers’ electricity.
