Considering the notable share of the residential sector in the electricity demand market along with renewables growth, potential impacts of the residential solar and batteries on the stability, power quality and operation of the power grid should be taken in account. In this paper, we develop optimization equations based on two different rating policy in California and South Carolina (SC) to investigate the effect of the different electricity tariffs on a residential customer’s load profile in presence of the solar panel and Electric Vehicle (EV). EV trip is simulated through an imaginary load profile based on EV consumption rate. Also, we propose a new rating policy to overcome the issues regarding to the current tariffs. Results show that customer’s load profile is highly sensitive to electricity tariff and the algorithm of EV connection to the grid. This sensitivity allows us to regulate tariffs in favor of both sides, customers and utilities.
