چکیده :

Growth of the population, the need for electrical energy, convince distribution companies (DISCO) to expand their activities and respond to the increase in demand. Computations of the considered model are executed at various load levels. The cost of Energy Not Supplied (ENS), energy losses, and revenue from the consumers' purchase of energy are affected in the maximizing of profit. Electric Vehicles Charging Stations (EVCS) placement was further scrutinized as a constraint along with Energy Storage Systems (ESS) and Distributed Generations (DG), with an examination of accurate load modeling for the first time in this essay. The obtained results demonstrate the expansion of the distribution system with AC load flow, in which the expansion of substations, lines, and DGs was considered. The results of planning cost, exclusively the construction and development of substations, are estimated to be higher than the cost of construction of DG and restoration of lines. Therefore, reinforcing and replacing the line conductors is the optimal decision for the system. This research deals with the increasing expansion cost by considering the DGs. This model's expertise is stronger than the lack of ESS, and their deployment reduces the energy cost at the peak. With the correct placement of EVCS, it satisfied their energy consumption. Eventually, the result of the study illustrates the profitability of the model.
