Four simulations have been done on the selected network; in case of the initial network, network with two distributed sources, network with two distributed sources and capacitive static VAR compensator and with inductive static VAR compensator. It is demonstrated how distributed resources affect the minimum voltage in the network, the maximum voltage in the network, loss o the network and the level of penetration. Adding static VAR compensators it is presented the way that capacitive and inductive static VAR compensators affect voltage conditions, losses in the network and the level of penetration. The minimum and maximum voltages are shown in each case at a moment when distributet sources are in maximum power. Dependance of active and deficient reactive losses in the nework on changing power o distributed sources is demonstrated. The manner in wich penetration level varies depending on the character of the connected static VAR compensator is also demonstrated.
