Abstract :
In spite of many profitable or advantageous natures of distributed generators (DGs), for power systems, such badly behaved natures of DGs as (1) unstable power output, (2) voltage problem, (3)harmonics, (4)reverse power flow, etc. also exist. Therefore, it has been always emphasized that the unfavorable effects should not exist when distributed generators are connected to the power system. However, in the situation that many distributed generators are connected to a power distribution system, we must utilize them as control resources for the power systems operation. In this paper, voltage control effects of the distributed generators connected to power distribution systems are discussed by using a simple example of a radial power distribution system. Through many simulation cases, voltage control effects for distribution systems are demonstrated.
