Abstract:
In this thesis, the problem is "the study of the role of electric vehicles in controlling the voltage and reactive power in the distribution network". Note that electric vehicles are connected to the network by the charger to charge your battery. Also, by choosing the right structure for a charger, which is a two-way charger, in addition to active power control, reactive power can be activated in both self-acting and capacitive modes. Therefore, electric vehicles have the ability to control reactive power and voltage in the network. In the following, the above problem is an optimization problem whose target function is equal to minimizing the cost of energy and voltage deviation from the desired value. It is worth noting that in addition to the objective function of the problem, the constraints of the problem include power transmission equations, electric vehicle equations, capacitor banks, dispersed wind and solar discharges, tapping and technical limitations of the distribution network.
In this case, the cost of energy, the production of wind and solar systems and some of the parameters of electric vehicles is uncertain, so in this thesis, a random scenario model is used. Scenario production by roulette wheel and scenario reduction by return method. Finally, the proposed issue is applied to the 33-bay distributed radial network of the IEEE standard using the GAMS software, and then the proposed project's capabilities are evaluated. According to the obtained results, it can be seen that the proposed scheme has the ability to improve the network indices at a high level.
Keywords: Electric vehicles, Reactive power control, Voltage control, Uncertainty.
