Many new technologies are being introduced to the electrical power grid at the distribution voltage level. These technologies include electric vehicles (EVs), distributed generation, and battery energy storage systems (BESS) This thesis investigates how these various technologies can be harmoniously integrated into the electric grid. Therefore, a modeling environment that can simulate scenarios involving the above technologies in durations from hours to years was created. This modeling system is modular so that any feeder configuration can be simulated by the user and each module has individual user defined parameters or curves that define their operation. Optimum economic dispatch, stability enhancement, renewable generation smoothing, and peak-shaving algorithms were implemented into the modeling environment. With the use of the built in algorithms, or custom input, the simulation tool produces the necessary electrical and economic values to fully evaluate the systemâ€™s feasibility. Other algorithms created include renewable generation smoothing and stability enhancement.
