Abstract

Co-simulation is an approach where the simulation of both transmission and distribution system gets combined. This approach provides more accurate description of the results which can help the decision making of the operator. Due to increasing rate of decentralization, there is bidirectional energy flow. Thus, getting uninterrupted power supply even under any kind of stressed situation is possible with the help of renewable energy sources (RES), distributed generators (DG) and electric vehicles (EV) in the system. EVs can act as a source and load depending on the discharging or charging characteristics. The power in the EVs can be discharged during stressed hours to manage over loading of transmission lines by avoiding line limit violation. The IEEE 30 bus system is considered as transmission system in which IEEE 33 bus system and IEEE 69 bus system as Micro Grids (MGs) are being integrated at three different buses. Load flow analysis is performed for different cases using MATLAB software. The reduction of MVA flow in the transmission line is observed when it is managed using RES integrated in transmission system while DGs and EVs present within the microgrids.
